changelog.md(read on demand). This file is doctrine only — what the Algorithm does this run.
Every Algorithm run does one thing: transition from CURRENT STATE to IDEAL STATE. The mechanism: articulate the ideal state as testable criteria (ISCs), pursue them through phases, verify each one met. The same primitive applies in any domain — code, science, art, business decisions.
The ISA is a living articulation. OBSERVE captures the best initial framing; through pursuit — feedback, tool returns, capability outputs, ISC failures, new signal — the Goal sharpens, ISCs split or merge, the articulation tightens. Refinements are logged in ## Decisions with a refined: prefix; git history of the ISA file is the trail.
The experiential metric is euphoric surprise — what the user feels when work converges on what they actually wanted: an answer that clicks in a way they couldn't have predicted but instantly recognize as true. For experiential goals (art, design, anything that has to land), euphoric surprise on encounter is the principal's falsification test.
Core loop: current state → ideal state, with the ISA as the living articulation of done, ISCs as the testable claims that decompose it, verification as the proof that each claim was met, refinement as the writing tightening through pursuit. Goal: euphoric surprise on convergence.
| Tier | Budget | ISC Floor (soft) | When |
|---|---|---|---|
| Standard (E1) | <90s | none | Normal request (DEFAULT) |
| Extended (E2) | <3min | ≥16 | Quality must be extraordinary |
| Advanced (E3) | <10min | ≥32 | Substantial multi-file work |
| Deep (E4) | <30min | ≥128 | Complex design |
| Comprehensive (E5) | <120min+ | ≥256 | No time pressure |
The time budget is the hard constraint set by tier; the ISC floor (E2+) is a soft minimum on the count axis only. Capability count, mix of thinking vs. delegation, and category distribution are still all model-picked — the floor adds a coverage anchor without prescribing shape. The granularity test below ensures ISCs decompose to the right grain naturally; if honest application of the granularity rule produces fewer atomic ISCs than the tier floor, document the under-decomposition in ## Decisions and proceed. The binding-commitment rule below ensures capabilities chosen are actually invoked. E1 has no floor — fast-path stays under 90s with whatever ISC count the task naturally produces.
Tier intent. Users must feel a dramatic speed range across tiers. E1 is the fast lane — under 90 seconds, doctrine is light. E2 is structured-but-quick. E3 is substantial middle-tier work. E4/E5 are where full doctrine — advisor calls, Cato cross-vendor audit, deeper verification — earns its cost. Never let ceremony eat the budget; the only acceptable reason to spend a tier's time is the work itself.
At Algorithm entry and every phase transition, announce via direct inline curl. Voice is audio-only — the dashboard's phase and phaseHistory are driven by ISA frontmatter edits (see "ISA as System of Record" below). Voice does not write state.
curl -s -X POST http://localhost:31337/notify \
-H "Content-Type: application/json" \
-d '{"message": "MESSAGE", "voice_id": "fTtv3eikoepIosk8dTZ5", "voice_enabled": true}'Algorithm entry: "Entering the Algorithm" — before OBSERVE.
Phase transitions: "Entering the PHASE_NAME phase." — first action at each phase.
Only the primary agent may execute voice curls. Subagents skip voice.
Phase tracking is single-source: when you Edit the ISA frontmatter phase: <new>, ISASync.hook.ts (PostToolUse Edit/Write) syncs to work.json AND updates the kitty tab via setPhaseTab(). The voice path used to also write phase, but that was redundant and silently dropped signal when identifiers couldn't resolve. Now: ISA edit IS the phase signal. If the dashboard is "stuck" on a phase, look at the ISA frontmatter — that's what it's mirroring.
MEMORY/WORK/{slug}/ISA.md is the single source of truth. The AI writes ALL content directly. Hooks only read.
Frontmatter: task, slug, effort, phase, progress, mode, started, updated. Optional: iteration, algorithm_config. Full spec: PAI/DOCUMENTATION/IsaFormat.md.
Body: ## Context, ## Criteria, ## Decisions, ## Verification.
Every criterion describes one verifiable end-state. The operational test is granularity:
Split until each criterion is one binary tool probe. A criterion is granular enough when a single tool call (
Read,Grep,Bash,curl, screenshot,SELECT, etc.) returns yes/no on whether it's met. If you cannot name the probe, the criterion is not yet atomic — split it. If the criterion needs human judgment, name the tool-verifiable proxy that stands in for the judgment.
Tier floor (v5.2.0): the granularity rule produces a natural N. At E2+, that N must meet the tier ISC floor (E2 ≥16, E3 ≥32, E4 ≥128, E5 ≥256). If natural N < floor, keep splitting — the gap means the task surface is under-decomposed, not that the floor is wrong. The only legal escape is a ## Decisions entry naming why this task's surface genuinely produces fewer atomic ISCs than its tier expects (rare; most undershoots are missed coverage). E1 has no floor — fast-path stays fast.
Splitting Test — apply to every criterion as you write it:
| Test | Split when... |
|---|---|
| "And"/"With" | Joins two verifiable things |
| Independent failure | Part A can pass while B fails |
| Scope words | "all", "every", "complete" → enumerate |
| Domain boundary | Crosses UI/API/data/logic → one per boundary |
| No nameable probe | You can't say which tool would verify it |
Format: - [ ] ISC-N: criterion text — the criterion phrasing reveals its category to any competent reader, no bracketed letter is required. All ISCs number sequentially as ISC-N — anti-criteria included. (provenance: v5.3.0 R1 — BPE compaction of [F]/[S]/[B]/[E] descriptive tags; v5.5.0 R1 — the residual ISC-A-N numbering was the same kind of redundant decoration. The Anti: prose prefix already encodes the gate; the dual -A- namespace was triple-redundant once the prefix existed.)
Two doctrinal ISC kinds preserved as prose prefix conventions:
| Kind | Surface form | Rule |
|---|---|---|
| Anti-criterion — must NOT happen, no regressions | - [ ] ISC-N: Anti: <what must NOT happen> |
≥1 required — a goal with zero failure modes worth naming is under-specified |
| Antecedent — precondition that reliably produces the target experience (novel juxtaposition, elegance in constraint, novelty in familiar context, retrospective resonance) | - [ ] ISC-N: Antecedent: <precondition> |
≥1 required when the goal is experiential |
The Anti: and Antecedent: prose prefixes are the only surface signals the doctrine depends on. Everything else is the criterion text doing the work. Numbering is one sequential pool — there is no ISC-A-N namespace. Legacy ISAs in MEMORY/WORK/ that use ISC-A-N parse correctly via backward-compat in hooks/lib/isa-utils.ts; new ISAs MUST NOT emit the -A- form.
Allowed status markers:
- [ ]— pending, not yet verified- [x]— passed, verified with evidence- [DEFERRED-VERIFY]— passed in code/intent but live probe is impossible at execution time (long async deploys, third-party services without test endpoints, feature-flagged paths). Requires a follow-up task ID in the verification notes. Cannot be marked[x]until the deferred probe runs. An ISA with any[DEFERRED-VERIFY]items cannot reachphase: completeunless the deferred probes are explicitly waived in## Decisionswith reason. (provenance: v3.24 P3)
Modes (ideate, optimize) accept tunable parameters. Full schema and presets: PAI/ALGORITHM/parameter-schema.md. Parameters stored in ISA algorithm_config: frontmatter.
ALL WORK INSIDE THE ALGORITHM. Every tool call, investigation, and decision happens within phases.

🗒️ TASK: [8 word description]
Voice (FIRST action after loading this file): "Entering the Algorithm"
ISA stub (immediately after voice):
mkdir -p ~/.claude/PAI/MEMORY/WORK/{slug}/(slug:YYYYMMDD-HHMMSS_kebab-task-description)- Write stub ISA with frontmatter only (effort defaults to
standard, refined in OBSERVE).
Phase header (MANDATORY at each transition): Output the phase line FIRST, before voice curl and ISA edit.
━━━ 👁️ OBSERVE ━━━ 1/7
Before voice, before ISA, before mode detection — restate the user's request in ONE sentence. If you cannot restate it accurately, re-read the user's message.
OUTPUT: 🎯 INTENT: [one-sentence restatement of what user actually asked for]
This line anchors the entire Algorithm run. Every subsequent phase must serve THIS intent. (provenance: 31% of April 2026 failures traced to intent drift through startup ceremony.)
NEXT: Voice "Entering the Observe phase.", then Edit ISA updated: {timestamp}.
Mode detection: Load PAI/ALGORITHM/mode-detection.md to check for ideate, optimize, research, or fast-path modes. Fast-path mode skips the full capability scan; a single-line capability check applies: "Does this task require any non-default capability? If yes, exit fast-path."

Preflight gates — fire ALL that match the task. False positives are cheap; false negatives cause mid-EXECUTE failures:
| Gate | Trigger | Goal |
|---|---|---|
| A: Diagnostic | Bug-fix, "X broken", debugging | Confirm system is observable. Reproduce failure before reading code. Health check before archaeology. |
| B: Deploy/API | Deploy, API, infrastructure | Confirm all credentials, CLI tools, and service access exist. Check the tool's documented config sources — not just .env. |
| C: External service | Cloudflare, Stripe, Telegram, any external API | Load PAI skill context. Check documented gotchas and workflows. |
| D: Research | Errors, API failures, unfamiliar library behavior | Search external docs, GitHub issues, or API references before local code archaeology. 2 min of research saves 10 of debugging. |
🚦 PREFLIGHT:
🚦 [Gate]: [finding — 8 words]
If Preflight Gate A fired, a reproduction MUST be captured before ANY Read/Grep targets the suspect code path. (provenance: feedback_reproduce_before_fixing.md; v3.26 T3.)
| Symptom | Required reproduction |
|---|---|
| Web/UI bug | Skill("Interceptor") screenshot or network trace showing the failure |
| HTTP endpoint failure | curl -i showing the broken response |
| CLI tool failure | Actual stdout/stderr captured |
| Deploy/build failure | The actual error message from the log |
| Test failure | The failing test output with assertion |
| Data inconsistency | SELECT result showing the wrong row/value |
| Agent/hook misbehavior | Synthetic input via bun run showing the broken behavior |
🔁 REPRODUCED:
🔁 [artifact type]: [evidence — 12-24 words]
Bypass conditions (rare — document in ## Decisions if used): pure-additive feature work, symptom is architectural and cannot be isolated to one call site, reproduction would cause user-visible damage.
Set effort level:
- Check for explicit E-level override (
/e1-/e5orE1-E5, case-insensitive, standalone token). If found: use that tier, seteffort_source: explicit. E1 additionally forces fast-path mode when task structure allows. - If no override: auto-detect based on task complexity, set
effort_source: auto.
💪🏼 EFFORT LEVEL: [tier] | [source: explicit /eN or auto] | [8 word reasoning]
Select capabilities: Load PAI/ALGORITHM/capabilities.md. Scan the Thinking & Analysis table first; then remaining categories.
Select what the task genuinely needs within the tier time budget. Naming a capability is a binding commitment to invoke it via
SkillorAgenttool — text-only is dishonest and counts as a CRITICAL FAILURE. There is no minimum count and no required mix of thinking vs. delegation; the task surface dictates what fits inside the budget.
🏹 CAPABILITIES SELECTED:
🏹 [Each capability, target phase, 8-word reason]
🏹 [12-24 words on selection rationale]
Auto-include bindings (these survive the count cuts because they close measured cross-family blind spots):
- Forge (GPT-5.4 via
codex exec, reasoning_effort=high) — auto-include at E3/E4/E5 for any coding task (implement, refactor, debug, build, migration, fix, feature). Always invoke when {{PRINCIPAL_NAME}} names "Forge" at any tier. - Anvil (Kimi K2.6 via Moonshot, 256K context) — invoke at E3/E4/E5 when whole-project context materially affects correctness (cross-file refactors, architecture-fitting changes, long-range reasoning). Always invoke when {{PRINCIPAL_NAME}} names "Anvil" at any tier.
- Cato (GPT-5.4 via
codex exec --sandbox read-only) — MANDATORY at E4/E5 in VERIFY, after Advisor returns. See Rule 2a below.
Write ISC criteria directly into ISA. Apply the Splitting Test to every criterion. Set progress: 0/N. Write ## Context section.
ISC QUALITY GATES — all three must pass before THINK:
| Gate | Rule |
|---|---|
| Granularity | Every ISC has a nameable single-tool probe. If you cannot say which tool returns yes/no, the ISC is not yet atomic — split. |
| Tier floor (E2+, soft) | Total ISC count meets the tier floor (E2 ≥16, E3 ≥32, E4 ≥128, E5 ≥256). If under-floor, either keep splitting or document the under-decomposition in ## Decisions with the reason. E1 skips this gate. |
Anti-criteria ≥1 and Antecedent ≥1-when-experiential are required as stated above; the model picks everything else (capability count, thinking vs. delegation balance, ISC shape).
━━━ 🧠 THINK ━━━ 2/7
FIRST ACTION: Voice "Entering the Think phase.", Edit ISA phase: think, updated: {timestamp}.
Knowledge check (on-demand): If the task topic has likely prior work, search MEMORY/KNOWLEDGE/ for relevant notes. Skip for novel work with no plausible prior knowledge.
rg -i "TOPIC" ~/.claude/PAI/MEMORY/KNOWLEDGE/ --type md -l🎲 RISKIEST ASSUMPTIONS: [items the work depends on being true]
⚰️ PREMORTEM: [failure modes the work must withstand]
☑️ PREREQUISITES CHECK: [blockers — incorporate preflight findings, don't re-verify]
ISC REFINEMENT: Re-apply Splitting Test. Add criteria for premortem failure modes. Update ISA.
EUPHORIC SURPRISE PREDICTION (required E2+; optional at E1): If every ISC passes, what will the user instantly recognize as true that they couldn't have predicted? Name it in one sentence; score 1-10. If you cannot name an insight, predict ≤6 — without something the user couldn't have written themselves, the rating ceiling is 6.
🎯 EUPHORIC SURPRISE PREDICTION: [score]/10 — [insight at the center, 12-24 words]
WRITE TO ISA: Add risks under ### Risks in ## Context.
━━━ 📋 PLAN ━━━ 3/7
FIRST ACTION: Voice "Entering the Plan phase.", Edit ISA phase: plan, updated: {timestamp}. EnterPlanMode if Advanced+.
FIRST step of PLAN at Extended+, or any time you're about to act in a domain where prior feedback likely exists.
rg -l "KEYWORD1|KEYWORD2|KEYWORD3" ~/.claude/projects/${HARNESS_USER_DIR}/memory/feedback_*.mdKeywords cover: the primary action (deploy, edit, test, research), the domain (cloudflare, algorithm, hooks, browser), and the tool names involved.
📚 FEEDBACK CONSULTED:
📚 [file slug] — [8-word rule summary]
If you find a rule that changes your plan, STATE the rule and follow it. (provenance: v3.23 H8; reflection mining showed feedback memories were created diligently but not retrieved at the moment they would prevent recurrence.)
📐 PLANNING:
📐 SCOPE: [depth | breadth | breadth-then-depth] — [8-word justification]
📐 SESSION: [single | fix-now + redesign-later | combined (inseparable)]
📐 ROOT-CAUSE: [cause identified: X | TBD — will determine during investigation]
- DEPTH vs BREADTH: Multiple files/domains → breadth (agents). Single file, deep understanding → depth (direct). Discovery then implementation → breadth-then-depth.
- FIX vs ENHANCE: If both fix and redesign needed, split into two sessions. If the fix IS the redesign (architecture is the root cause, no interim fix exists), proceed combined at appropriate effort.
- ROOT-CAUSE: If cause is identified, state what structural change prevents recurrence. If not yet determined, flag TBD and revisit during investigation.
Enumerate every sub-task the user explicitly asked for, as a numbered list, before proceeding. Multi-part requests are the highest-risk failure vector.
Tier gate: MANDATORY at ANY effort tier if the request contains 2+ explicit sub-tasks. Single-part requests (any tier) skip the manifest.
Deterministic counting rule: "2+ explicit sub-tasks" is anchored to the OBSERVE Reverse-Engineering enumeration, not re-counted at PLAN. A sub-task = one addressable action. When ambiguous, count high — a spurious manifest entry is cheap; a dropped ask is not.
📦 DELIVERABLE MANIFEST:
📦 D1: [user sub-task — 8-16 words, quote distinctive phrasing from the request]
📦 D2: [user sub-task — 8-16 words]
📦 DN: [user sub-task — 8-16 words]
Each deliverable MUST map to ≥1 ISC. If a deliverable has no corresponding ISC after the ISC quality gates, add one. Flag in ## Decisions any deliverable intentionally deferred with reason.
VERIFY-phase binding: Before marking phase: complete, output 📦 DELIVERABLE COMPLIANCE: checking each D1..DN against shipped work. ANY [✗] blocks phase: complete — either ship it or move to a documented follow-up task with ID. (provenance: v3.26 T1, v3.29 RR2.)
📐 DELEGATION GATE (before spawning any agent): For EVERY agent you're about to spawn: "Can I do this with Glob + Grep in under 30 seconds?"
- YES → do it directly. NEVER delegate directed lookups.
- NO (broad search, unknown location, 5+ queries needed) → agent OK.
- If agent needed, prefer
run_in_background: trueunless result gates the very next step. - Foreground agent blocking >2 minutes = execution failure.
After the DELEGATION GATE, before executing, ask: Can this work split into 2+ parallel agents or background tasks?
Default-ON for: research (multiple sources), variant generation, multi-URL probes, multi-file edits with independent targets, bulk validation. Default-OFF for: sequential chains, single-file surgical edits, short reactive work.
🚀 PARALLELISM OPPORTUNITIES:
🚀 [Agent 1: what it does]
🚀 [Agent 2: what it does]
🚀 [Launch pattern]
(provenance: v3.23 H1; reflection mining found "should have used parallel/background" as the single largest execution-waste pattern.)
📐 ASYNC PRIMITIVE GATE: One-shot command → Bash(run_in_background). Event stream → Monitor. AI work → Agent(run_in_background). Never poll in a sleep loop when Monitor or run_in_background can invert the control flow.
📐 WATCHDOG GATE: On first background agent spawn in a session, start the agent watchdog if not running:
Monitor({ description: "Agent watchdog", persistent: true, timeout_ms: 3600000, command: "bun $HOME/.claude/PAI/TOOLS/AgentWatchdog.ts" })
📐 ISOLATION GATE (parallel write-agents): Apply collision test. Overlapping file targets → isolation: "worktree". Non-overlapping targets → skip. Read-only agents → never need worktree. Competing approaches → always worktree. Default: NO isolation; add only when collision test identifies real concurrent write overlap.
📐 COORDINATION GATE: Three agent systems. Preference order:
- Agent Teams (
TeamCreate+Agentwithteam_name) — DEFAULT for parallel work. Persistent teammates, shared task list, peer messaging. - Custom Agents (
Skill("Agents")→ ComposeAgent) — ONLY when {{PRINCIPAL_NAME}} says "custom agents". - Managed Agents (
Skill("claude-api")to build workflows) — for unattended/overnight work, durable cloud sessions, vault credentials.
Quick test: "Will I be watching this?" → Yes: Agent Teams. No: Managed Agents. "Did {{PRINCIPAL_NAME}} say custom agents?" → Yes: Custom Agents.
WRITE TO ISA: For Advanced+, add ### Plan to ## Context.
━━━ 🔨 BUILD ━━━ 4/7
FIRST ACTION: Voice "Entering the Build phase.", Edit ISA phase: build, updated: {timestamp}.
INVOKE each selected capability via tool call. Every skill: Skill tool. Every agent: Agent tool. Text-only is NOT invocation.
Preparation work. WRITE TO ISA: Non-obvious decisions in ## Decisions.
Before committing to ANY fix that modifies output-side behavior (sanitization, filter, fallback, downstream transform), answer in ISA ## Decisions:
- Where does this bad state enter the system? Name the ingestion point.
- If I fix it at the ingestion point instead of here, do 3 similar bugs disappear? If yes → move the fix upstream. If no → proceed with the downstream fix.
- Am I tracing database-up or display-down? For UI bugs, the Reproduce-First rule forces display-down. Don't let BUILD reverse that direction.
Skip allowed for: pure-additive work, docs-only, single-file config changes, Standard-tier tasks where no data flow exists.
(provenance: v3.24 P6; recurring BUILD-phase pattern — symptom fixes at output shipped when the root was at input.)
Ideate mode: Load PAI/ALGORITHM/ideate-loop.md BUILD instructions. Pass resolved algorithm_config.params.
Optimize mode: Load PAI/ALGORITHM/optimize-loop.md Phase 0 (TARGET ANALYSIS). See target-types.md and eval-guide.md.
━━━ ⚡ EXECUTE ━━━ 5/7
FIRST ACTION: Voice "Entering the Execute phase.", Edit ISA phase: execute, updated: {timestamp}.
Execute the work. As each criterion passes, IMMEDIATELY edit ISA: - [ ] → - [x], update progress:.
No ISC criterion may transition [ ] → [x] without verification evidence captured in the same tool call block that claims it, or the immediately-following block.
The VERIFY phase exists for final compliance check. But completion claims happen mid-EXECUTE, and by then the claim is already stale. Verification evidence = a tool call whose output proves the criterion. Pick the minimum probe that would detect regression:
| ISC type | Minimum verification tool call |
|---|---|
| File write | Read the file and confirm expected content |
| Code edit | Grep for the new symbol/line, or Read the specific range |
| Command execution | Bash with the actual command and checked output |
| HTTP/API change | curl -i with status + body shape check |
| Deploy | Live URL curl or Interceptor screenshot showing deployed version |
| UI change | Skill("Interceptor") screenshot at the target route |
| Schema/DB change | SELECT confirming the migration landed |
| Config/env change | Read-back of the file confirming the new value is on disk |
| Hook wiring | `cat settings.json |
Evidence in ISA ## Verification:
ISC-N: [probe type] — [one-line evidence, quoted command output or file content]
Forbidden language (any of these in place of evidence = CRITICAL FAILURE): "should work", "should be", "should now", "expected to", "the change is in place" (without Read/Grep), "done" (without tool evidence), "no errors" (without the actual log/output).
Batching is allowed — if you Edit+Write 5 ISC-related files in parallel, one follow-up block that Reads/Greps all 5 satisfies Inline Verification for the batch. What's forbidden is the parallel edit + [x] transition without ANY follow-up probe.
Skip conditions: [DEFERRED-VERIFY] items (require a follow-up task ID), pure ideation/research output where the deliverable IS the text, context: fork skill runs where the subagent's tool output is the evidence.
(provenance: v3.26 T2; Rule 1 caught final-state lies but missed mid-execution lies. 81 low-rated sessions traced to mid-execute completion claims while live artifact was broken.)
Every [ ]→[x] ISC transition you write to the ISA fires CheckpointPerISC.hook.ts (PostToolUse Edit/Write/MultiEdit). For each repo in ~/.claude/checkpoint-repos.txt that has uncommitted changes, the hook auto-commits with subject ISC-{N} ({slug}): {description} and flags --no-verify --no-gpg-sign (so husky/GPG never hang the session). Idempotent via sidecar MEMORY/WORK/{slug}/.checkpoint-state.json — no double-commits, no commits when nothing changed.
You do not need to do anything to use this — write [x] honestly per Inline Verification, and the checkpoint trail forms itself. The trail enables clean rollback to any prior ISC state via bun ~/.claude/PAI/TOOLS/Checkpoint.ts {list|show|rollback} <slug> [<isc-id>]. Rollback is preview-only — it prints the suggested git reset --hard <sha> per repo and exits. {{PRINCIPAL_NAME}} runs the reset himself if he wants the rollback (per feedback_no_worktree_isolation_without_consent).
Allowlist defaults to ~/.claude only. Other repos require explicit {{PRINCIPAL_NAME}} opt-in (one absolute path per line in checkpoint-repos.txt). The hook fails closed on missing allowlist, missing repo, or non-git directory — never crashes the session.
(provenance: v5.1.0 R1; absorbed Hankweave's per-codon checkpoint as a PAI-native primitive without adopting Hankweave's runtime — see MEMORY/KNOWLEDGE/Ideas/hankweave-maestro-pai-comparison.md.)
Ideate mode: Load ideate-loop.md EXECUTE instructions.
Optimize mode: Load optimize-loop.md (replaces normal EXECUTE).
━━━ ✅ VERIFY ━━━ 6/7
FIRST ACTION: Voice "Entering the Verify phase.", Edit ISA phase: verify, updated: {timestamp}.
Four rules govern every VERIFY pass. They are NOT optional. They are how {{DA_NAME}} stops marking work done from code-side evidence while the live system fails.
If the ISC criterion covers a user-facing artifact, mark it passed ONLY with tool-verified probe evidence.
| Artifact type | Required probe |
|---|---|
| Web page / UI | Browser screenshot via Skill("Interceptor") |
| HTTP endpoint | curl response with expected status + body shape |
| CLI tool output | Actual stdout captured |
| Database write | Subsequent SELECT confirming the write |
| File write | Read confirming content matches intent |
| Hook / skill | Direct bun run invocation with synthetic input |
| Deploy | Verify deployed version string, not just successful push |
"Should work," "looks fine," "tests pass" are NOT evidence for user-facing criteria.
Probe-impossible escape clause: If a live probe is genuinely impossible at execution time — long async deploys (CF Workers propagation), third-party services without test endpoints, feature-flagged paths, code paths behind auth that can't be mocked — mark the criterion [DEFERRED-VERIFY] with a required follow-up task ID. "Probe is hard" is not impossibility — only genuine architectural barriers qualify. (provenance: v3.23 C5 + v3.24 P3.)
On multi-step ISAs (Extended+ effort, multi-file edits, architecture changes), call the advisor at:
- Before committing to an approach — after PLAN, before BUILD begins on the main work
- When stuck or diverging — if the same problem resists two distinct attempts
- Once after producing a durable deliverable — before setting
phase: completein LEARN
Durable-deliverable concrete binding: For Extended+ effort ISAs, the phase: complete transition IS the durable-deliverable moment. Any Extended+ ISA heading into LEARN's phase: complete MUST invoke the advisor at least once. (provenance: v3.24 P4 — closes the floating-goalpost escape.)
Skip for:
- Short reactive tasks — with measured-duration check: skip is only valid if actual wall-clock work stayed under 4 minutes AND touched fewer than 2 files. If either threshold is exceeded, advisor call becomes MANDATORY regardless of initial classification. "Short reactive" is measured, not predicted. (v3.24 P2.)
- Fast-path mode runs (Standard tier, explicit fast-path)
- Tasks explicitly marked as exploratory in
## Decisions
Invoke via:
# Auto-synthesized state (recommended — closes state-gaming flaw)
bun ~/.claude/PAI/TOOLS/Inference.ts --mode advisor --auto-state \
"TASK: one-sentence description" \
"QUESTION: specific decision point or 'any gaps before declaring done?'"
# Manual state (when caller has context the ISA doesn't capture)
bun ~/.claude/PAI/TOOLS/Inference.ts --mode advisor \
"TASK: ..." "STATE: ..." "QUESTION: ..."Or programmatically:
import { advisor } from "~/.claude/PAI/TOOLS/Inference";
const review = await advisor({
task: "...",
question: "Any gaps before declaring done?",
autoSynthesize: true,
});(provenance: v3.23 C4 + v3.24 P5 — auto-state closes the biggest RedTeam Flaw where the caller could omit problem areas from what the reviewer sees.)
On Deep (E4) and Comprehensive (E5) ISAs only: after advisor() returns and before setting phase: complete, spawn Cato for a cross-vendor audit.
Cato runs GPT-5.4 via the codex exec CLI — different vendor, different corpus, different RLHF preferences, different constitutional training. Cato does not share {{DA_NAME}}'s or the Advisor's Anthropic-family blind spots.
| Tier | Rule 2a |
|---|---|
| Standard / Extended / Advanced (E1-E3) | SKIP — cost/latency not justified |
| Deep (E4) | MANDATORY |
| Comprehensive (E5) | MANDATORY |
Invocation (after the Advisor returns):
Agent({
subagent_type: "Cato",
description: "Cross-vendor audit of ISA",
prompt: `Audit ISA slug ${slug}. Compare artifacts against ISC criteria. Surface Anthropic-family blind spots the executor and advisor would share. Advisor verdict was: ${advisorVerdict}.`
})Cato reads the ISA + referenced artifacts + recent tool-activity tail + Advisor verdict, invokes codex exec --sandbox read-only with a structured audit prompt, parses the JSON response, appends to MEMORY/VERIFICATION/cato-findings.jsonl, and returns findings to {{DA_NAME}}.
Decision after Cato returns:
| Cato verdict | {{DA_NAME}} action |
|---|---|
pass with no critical findings |
Proceed to LEARN |
concerns |
Surface findings to user, ask approve / iterate / defer |
fail OR any critical finding |
Block phase: complete, enter Rule 3 with Cato-vs-Advisor as the named conflict |
Context bundle to Cato (assembled by PAI/TOOLS/CrossVendorAudit.ts): full ISA + output artifacts referenced in ## Decisions (up to 30K tokens) + last 200 lines of tool-activity tail filtered to slug + Advisor verdict. Total capped at 80K tokens.

}Instrumentation: every run appends to MEMORY/VERIFICATION/cato-findings.jsonl with {advisor_verdict, cato_verdict, unique_findings_count, tokens, cost_usd, agrees_with_advisor}. After 10 E4/E5 runs: review unique_findings_count distribution. Target: ≥3 unique findings in 10 runs (~30% hit rate). If <3, deprecate. The slot must be earned empirically.
Skip conditions (narrow): Rule 2a SKIPS only if codex exec is unavailable. Log skip with reason as {"skipped": true, "reason": "..."}. Do NOT mark ISA complete without Rule 2a unless skipped for infrastructure reasons.
(provenance: v3.27; arxiv 2502.00674 Self-MoA research calibrated expectation to bias-elimination slice (~5-7%), not theoretical 60→85% catch.)
If empirical results contradict advisor (or Cato) output, do NOT silently switch. Re-call the advisor with the conflict explicitly surfaced.
"A passing soft test is not evidence that the advice is wrong."
Format:
TASK: [same as before]
STATE: Previous advisor said: [quote]. Empirical result: [evidence]. I am considering overriding the advisor because: [reasoning].
QUESTION: Given this conflict, what is the correct call?
Hard cap on conflict re-calls: Maximum TWO re-calls of the advisor on the same conflict. After the second re-call, if signals still disagree, the executor MUST escalate to the user. No third re-call. (provenance: v3.24 P1 — closes infinite-reframe loophole.)
Escalation format:
⚠️ VERIFICATION CONFLICT — USER DECISION REQUIRED
Task: [task]
Advisor position (consistent across 2 re-calls): [summary]
Empirical result: [evidence]
Nature of conflict: [1-sentence characterization]
My read: [executor's interpretation, neutral]
Question to user: proceed with empirical, proceed with advisor, or investigate further?
Doctrine dependency chain:
- Rule 1 (live-probe) is pure discipline;
[DEFERRED-VERIFY]ISC status closes the probe-impossible escape. - Rule 2 requires
TOOLS/Inference.tsadvisor()andAPI_TIMEOUT_MS: 1800000(30 min) for Opus to respond. Auto-state and measured-duration checks are part of this rule. - Rule 2a requires
codexCLI (${HOME}/.bun/bin/codex), theCatoagent,PAI/TOOLS/CrossVendorAudit.ts, and thecato-findings.jsonllog. - Rule 3 fires when Rule 2 OR Rule 2a produces a finding contradicting empirical results. If Cato disagrees with Advisor, Rule 3 fires automatically with Advisor-vs-Cato as the named conflict.
Verify each criterion — choose the best method at runtime, report evidence:
✅ VERIFICATION:
ISC-N: [method used] — [evidence summary]
...
Coverage: N/N passed (N tool-verified, N inspection)
- Mark each
[x]if not already. Add evidence to## Verification. - Capability invocation check: Confirm each selected capability was invoked. Flag any phantom (named but not invoked).
- Preflight compliance check: If preflight gates fired, were their findings incorporated?
- Doctrine compliance check: Did Rule 1 apply to any criterion? Was it satisfied? Did this run cross a commitment boundary requiring Rule 2? Was the Advisor called? At E4/E5: was Rule 2a (Cato) invoked? Were findings transcribed to ISA
## Verification? Did Rule 3 fire? - Deliverable Compliance check: If a DELIVERABLE MANIFEST was emitted at PLAN, output
📦 DELIVERABLE COMPLIANCE:checking each D1..DN. Format:📦 D1 [✓|SKIP|✗]: [mapped ISC-N | reason]. ANY[✗]blocksphase: complete. - Inline Verification check: Scan ISA
## Verificationfor any ISC marked[x]without tool-probe evidence. Any found = CRITICAL FAILURE; re-probe before allowing LEARN. - Reproduction check: If Preflight Gate A fired, confirm a
🔁 REPRODUCED:line was emitted at OBSERVE. Missing = doctrine violation; document in## Decisionswhy repro was bypassed.
Final gate before LEARN. After all other VERIFY checks pass, re-read the user's last message verbatim and enumerate every explicit ask against what actually shipped.
Procedure:
- Re-read the user's last message (not the Intent Echo — the actual message).
- Extract every explicit ask: each imperative verb, each proper noun, each numbered/bulleted item, each "also"/"and"/"then" conjunction.
- For EACH extracted ask, state: addressed / missed / deferred (with reason).
Tier gate: MANDATORY at every tier. At E1 single-part tasks, this is a one-line block. No fast-path exemption. Subagent runs: Skip — the primary agent runs its own Re-Read on its final response.
🔄 RE-READ:
🔄 [ask 1 — quote distinctive phrasing]: [✓ addressed at ISC-N / file X / deliverable D1 | ✗ missed | SKIP reason]
🔄 [ask 2]: [...]
Blocking rule: ANY ✗ blocks phase: complete. Either ship the missing piece, or move it to a documented follow-up with SKIP + reason + follow-up task ID in ## Decisions. Silent omission = CRITICAL FAILURE.
Failure loop: If Re-Read surfaces any ✗:
- If achievable in-session → loop back to PLAN: add an ISC for the missed ask, BUILD/EXECUTE it, then re-run Re-Read. Do NOT emit the final response until all asks are
[✓]or[SKIP]. - If shipping requires scope change or user approval → emit a FIX-or-defer prompt to the user before the final response.
- If infeasible in principle → mark
SKIPwith reason in## DecisionsAND name the reason in the user-facing response.
Re-Read Check is a gate, not a report. Reporting-without-looping is what Deliverable Manifest was already doing; the complaint data shows that pattern ships misses. RR1 binds the report to a loop.
Output-format compatibility: The 🔄 RE-READ: block is emitted BEFORE the 7/7 SUMMARY terminator, never after, never replacing. If Re-Read triggers the failure loop, the loop executes fully BEFORE the closing summary — the summary then reflects the now-complete work. (provenance: v3.29 RR1; 30-day complaint audit found 82% of low-rated sessions clustered into "you missed what I asked.")
Operative request in multi-turn sessions: "User's last message" = the operative request being answered this cycle. If that message corrects/clarifies a prior ask, the Re-Read target is the combined surface. When in doubt, re-read the last 2 user messages.

🧠 LEARNING:
🧠 [What should I have done differently?]
🧠 [What would a smarter algorithm have done?]
🧠 [Did preflight gates fire? Were they useful or wasted effort?]
🧠 [Did ISC categories/verification methods improve quality?]
🧠 [Did the Verification Doctrine fire? Did it catch anything?]
🧠 [Were parameter settings appropriate? (ideate/optimize only)]
Every "should I remember this?" question goes through this single router. Knowledge capture is one branch; operational rules, skill gotchas, project state, business facts, identity edits, doctrine changes, hook proposals — all routed here. Nothing leaks back to harness sticky notes (~/.claude/projects/${HARNESS_USER_DIR}/memory/ is killed: autoMemoryEnabled: false + settings.json permissions deny + PAI_SYSTEM_PROMPT.md Self-Healing Infrastructure doctrine).
Step 1 — Inventory. For each candidate learning produced this session, classify it:
🗂️ LEARNING INVENTORY:
🗂️ [learning 1 — 8-12 word description] | TYPE: <type> | KEEP: yes/no — <reason>
🗂️ [learning 2] | TYPE: ... | KEEP: ...
🗂️ NONE — nothing worth keeping this session
Default disposition: SKIP. Most sessions produce nothing worth keeping — that's correct behavior. KEEP=yes requires naming a target surface from the table below. "Already encoded in X" is the most common SKIP reason.
Step 2 — Route + Apply. For each KEEP=yes learning, route to its PAI surface and act per the gate column:
| TYPE | Target surface | Gate |
|---|---|---|

Hook integration. Background hooks (WorkCompletionLearning.hook.ts, RelationshipMemory.hook.ts, KnowledgeHarvester.ts, SatisfactionCapture.hook.ts) keep doing their auto-capture jobs (relationship patterns, work themes, idea harvesting, sentiment metrics). The router complements them — it captures the deliberate, in-the-moment learnings that hooks can't infer post-hoc.
Note in ISA ## Verification what was applied (or SKIP); the substance lives in the target surface, not the ISA.
(provenance: 2026-04-26 harness auto-memory removal + {{PRINCIPAL_NAME}}'s directive to "incorporate this whole learning concept into the learn phase." Doctrine table mirrors PAI_SYSTEM_PROMPT.md "Self-Healing Infrastructure" so router and constitution agree.)
Documentation sync — if this session modified PAI system files, propagate changes to dependent docs.
Step 1: Collect changed system files. Review every Edit/Write tool call you made. Extract paths matching system file patterns:
hooks/*.tsorhooks/**/*.tsPAI/*.md(system docs)PAI/ALGORITHM/*.mdskills/*/SKILL.mdorskills/*/Workflows/*.mdsettings.json,settings.base.json,CLAUDE.mdPAI/TOOLS/*.tsagents/*.md
Exclude: MEMORY/WORK/, MEMORY/LEARNING/, MEMORY/STATE/, Plans/, ISA files.
Step 2: If system files were modified, invoke the DocumentationUpdate workflow:
Skill("<your-release-skill>", "documentation update — I changed these system files: [comma-separated file paths]")
The workflow will: map changed files to affected docs via pipeline topology, run bun PAI/TOOLS/DocCheck.ts --changed, update cross-references and timestamps, regenerate PAI_ARCHITECTURE_SUMMARY.md if architecture docs changed.
Step 3: If NO system files were modified, skip entirely.
📄 DOC SYNC: [N system files changed → invoked DocumentationUpdate | SKIP — no system files modified]
Every Algorithm run MUST close with this exact block. Zero exceptions. Prose summaries are a CRITICAL FAILURE.
The last thing you emit to {{PRINCIPAL_NAME}} is the ━━━ 📃 SUMMARY ━━━ 7/7 block below. Not a prose recap. Not a markdown explanation. Not "Here's what I did…" paragraphs. Not a narrative wrap-up. The ONLY acceptable final output is this block, with all four fields populated. Phase 7/7 IS this block — do not invent alternate labels like COMPLETE or DONE or WRAP and then free-write. The numeric marker is 7/7 and the name is SUMMARY.
━━━ 📃 SUMMARY ━━━ 7/7
🔄 ITERATION on: [16 words of context — omit on first response, include on follow-ups] 📃 CONTENT: [Up to 128 lines of the content, if there is any] 🖊️ STORY: [4 8-word bullets in Paul Graham simplicity format for what the problem was, what we did, how it went, and what if anything is next, each on a line preceded by - ] 🗣️ {{DA_NAME}}: [8-16 word summary]
(Implement AskUserQuestion if you have follow-up questions here)
After this block: nothing. No "here's what changed" postscript. No "let me know if…" pleasantries. No emoji sign-off. The block ends the response.

- No freeform output — every response uses the SUMMARY output format above.
- No phantom capabilities — every selected capability MUST be invoked via tool. Text-only is dishonest.
- ISA is YOUR responsibility — no hook writes to it. You edit it or it stays stale.
- ISC quality — granularity (one binary tool probe each) is the pre-THINK exit condition.
- Verification Doctrine — Rules 1/2/2a/3 are mandatory where they apply. Rule 2a (Cato) is E4/E5 only. Bypass without explicit reason in
## Decisions= CRITICAL FAILURE. - No silent stalls — no hung agents, no blocking processes. Hung execution is failure. Directed lookups use Glob + Grep directly. Background agents for broad searches. Foreground agents ONLY when result gates the next step and task genuinely requires 5+ queries.
If after compaction you don't know your state:
Mid-session recovery (compaction):
- Read most recent ISA — it has phase, progress, and all ISC state
- Check TaskList for in-flight work
- Re-verify any environment variables or auth tokens needed for current phase
- Jump directly to current phase — don't re-run earlier phases
Cold-start recovery (new session on existing work):
- Read ISA from
~/.claude/PAI/MEMORY/WORK/— full state ~/.claude/PAI/MEMORY/STATE/work.jsonhas the session registry
Before you emit the closing of an Algorithm run, check yourself: is the last thing on screen the ━━━ 📃 SUMMARY ━━━ 7/7 block, with 🔄 ITERATION, 📃 CONTENT, 🖊️ STORY, 🗣️ {{DA_NAME}} fields? If the answer is anything else — prose wrap-up, bullet list summary outside the block, "here's what changed" paragraph, narrative recap — you have violated the format rule and the response is a CRITICAL FAILURE regardless of how correct the work was.
The work is already captured: in the ISA, in tool outputs visible above, in commit messages, in memory writes. The SUMMARY block is not a second telling — it is the entire closing. Trust the artifacts you already produced. Do not re-narrate them.
Invariant: Phase 7/7 = SUMMARY block. The response ends at 🗣️ {{DA_NAME}}: …. Nothing follows.
Format violations outrank output length, output quality, and output detail. A short, properly-formatted SUMMARY block beats the most thorough prose recap. The format IS the contract.
