Hi Fernando — I've been working on cc-safe-setup's operator-side defenses and shipped a four-hook cluster this month for what I think is an adjacent axis to AgentCloseoutBench's four categories (wrap_up / cliffhanger / roleplay_drift / sycophancy). Filing this as an issue rather than a PR because I'd like to think through the boundaries with you before either of us commits to a particular integration shape.
| Axis |
Where it fires |
What it measures |
Detection surface |
| AgentCloseoutBench (your work) |
Closeout boundary (final assistant message) |
Deception in the assistant's text output |
NLP/regex on text |
| cc-safe-setup sub-agent cluster (my work) |
Dispatch boundary (PreToolUse-Agent and adjacent) |
Divergence between dispatch claims and session log |
Event-level (tool-call counts, receipts, allowlists) |
The May 2026 GitHub issue cluster on anthropics/claude-code (#60987, #61102, #61107, #61167, #61315, #61405, #61547) consolidates into four sub-patterns at the dispatch boundary: dispatch fabrication (claim of completion with zero tool calls), silent stall (sub-agent blocks on hidden condition, blocked-state not propagated), absence of observation and control (12-hour silent hang), and scope expansion (sub-agent output treated as authorization rather than evidence). |
|
|
|
The cleanest case in the cluster — #61167, nvst18's OpenClaw trauma therapy deployment — reads as a sycophancy-flavored failure at AgentCloseoutBench's level (Claude reported success with confidence) and a dispatch-fabrication failure at the cc-safe-setup level (5 verification agents returning success with 0 sessions per agent). The same incident exposes both axes. |
|
|
|
1. Is sycophancy defined to include dispatch-claim sycophancy, or only conversational flattery? From DATASET_CARD.md it reads as the latter (operator-facing flattery about the user), but the boundary feels fuzzy. The closeout-side message "I successfully dispatched 39 specialized agents" (when 5 ran) is dispatch-fabrication operationally and sycophancy semantically. Two ways to read this: |
|
|
|
- (a) AgentCloseoutBench scopes to text-only deception; dispatch-substrate divergence is out of scope. Then the two benches are orthogonal and the integration story is "run both."
- (b) AgentCloseoutBench's
sycophancy quietly subsumes dispatch-claim sycophancy at the text level (the model says it did X). Then there's an interesting joint fixture: same record judged differently when the substrate is checkable vs not.
I read the spec as (a), but want to confirm before drafting fixtures.
2. Would a fixture pack from public-derived adversarial samples in the dispatch cluster be useful? I have permission-clean text excerpts from the seven issues above (the operators' own quoted descriptions of the failure narratives Claude generated). If those qualify as "public-derived adversarial samples" in your v0.3 corpus shape, I'd be happy to PR a small fixture pack (~10–15 records, properly category-tagged) and cite the corresponding GitHub issues. If they don't fit the v0.3 shape, no problem — happy to instead just publish them in cc-safe-setup as a separate closeout-narrative-fixtures/ directory and cross-reference.
- Not asking you to depend on cc-safe-setup or vice versa.
- Not asking for a hook adapter in either direction (the event-level vs text-level distinction makes a clean adapter hard).
- Not proposing schema overlap with the receipt-persistence layer (PR #282/#283/#286/#298 on cc-safe-setup — that's a separate substrate for the dispatch axis and shouldn't pollute your closeout corpus).
A short cross-reference section in each repo's README naming the other and the boundary between them. AgentCloseoutBench owns the closeout-text axis; cc-safe-setup's sub-agent cluster owns the dispatch-event axis. Operators install both for full surface coverage. The README sections cite the OpenClaw case (#61167) as the canonical example of an incident that exposes both axes.
If you want a fixture pack PR, I'll draft and send. If you'd rather keep the corpus shape stable for v0.3, the README cross-reference alone is enough from my side.
