feat(skills): add local skill CLI support

[anandh8x]

Summary

• add local skills CLI commands for listing, showing, validating, and removing skills
• support project/user/bundled skill discovery with project precedence
• keep skills CLI output free of the startup banner and format list output as a readable table
• add JSON output for skills list metadata

Scope

This covers the OpenClaude CLI read/manage portion of the Skill Hub. Registry install, the separate skills registry repo, and website catalog work are intentionally left for follow-up PRs.

Tests

• bun test src/cli/handlers/skills.test.ts src/skills/loadSkillsDir.test.ts src/commands.test.ts
• bun run build

[anandh8x]

Correction to the CI follow-up comment above: the shell expanded Markdown backticks while posting it, so here is the clean version.

CI follow-up update:

• Fixed the PR-added skills tests so they pass under the full Bun CI suite:
  • switched the new skills formatter test to bun:test
  • isolated the user-vs-project skill precedence assertion from shared process config state
• The skills-related tests are now passing in the GitHub Actions log.
• Also stabilized src/utils/conversationArc.perf.test.ts, which was failing CI because it used persisted shared knowledge-graph state plus strict wall-clock benchmark thresholds on a shared runner. The benchmark now uses an isolated temp config directory and coarse regression limits.

Local verification before pushing the latest fix:

bun test src/utils/conversationArc.perf.test.ts src/skills/loadSkillsDir.test.ts src/cli/handlers/skills.test.ts src/commands.test.ts
bun run smoke

web is passing. smoke-and-tests is currently rerunning after the latest push.

[Vasanthdev2004]

Thanks for pushing this forward. I reviewed the current head as a targeted Skill Hub CLI review, focusing on local/registry install behavior, skill discovery precedence, validation, banner suppression, and the new list/show/remove flow.

Verdict: Needs changes

Blocking issue:

1. The install flow needs to validate/sanitize the skill name before using it in filesystem paths.

In src/cli/handlers/skillsInstall.ts, prepareSkillFromMarkdown() can take registryEntry.name or SKILL.md frontmatter name, then immediately builds tempDir = join(tempRoot, skillName). Later cleanup removes dirname(candidate.tempDir). If a registry entry or raw SKILL.md uses a path-like name such as .. or ../x, the temp path and cleanup target can escape the intended temp skill folder before validateSkillPath() reports the invalid name.

Please fix this before merge by making the install path construction safe before validation runs. A good shape would be:

• validate/normalize the candidate skill name before any join(tempRoot, skillName) or install target path is created
• keep the original tempRoot as a separate field and remove that exact directory in finally, instead of deriving cleanup from dirname(candidate.tempDir)
• verify the final target directory resolves inside the intended skills root before rm/cp, especially for --force
• add a regression test for an invalid/path-traversal skill name from a raw SKILL.md or registry entry

What I checked:

• skills list/show/validate/install/remove command shape
• .openclaude/skills vs legacy .claude/skills precedence
• banner suppression for skills management commands
• local directory and registry install tests
• CI status

Local verification I ran:

• bun test src/cli/handlers/skills.test.ts src/skills/loadSkillsDir.test.ts src/commands.test.ts
• bun run build
• git diff --check

Those checks passed, and the overall direction is good. I just do not want this install path to merge until the pre-validation filesystem boundary is hardened.

Non-blocking note: registry installs currently only enforce sha256 when metadata provides it. For the Skill Hub trust model, I’d prefer requiring hashes for the default registry path, or at least making no-hash registry installs an explicit maintainer decision.

[anandh8x]

Addressed the requested install path hardening in commit 361a4ac.

Changes made:

• validate the install skill name before any temp or target path is constructed
• keep the temp root as an explicit cleanup target instead of deriving it from the candidate path
• resolve final install targets under the selected skills root before copy/force overwrite
• added regression coverage for path-like names from both raw SKILL.md and registry metadata

Verification:

• bun test src/cli/handlers/skills.test.ts src/skills/loadSkillsDir.test.ts src/commands.test.ts
• bun run build
• bun run smoke
• git diff --check
• GitHub Actions: smoke-and-tests and web are passing on the latest run.

[Vasanthdev2004]

Targeted re-review of the latest Skill Hub CLI fixes.

Verdict: Approve-ready

What I rechecked:

• the previous install-path blocker around unsafe skill names
• temp directory cleanup behavior
• target path containment before rm / cp
• raw SKILL.md and registry path-traversal regression coverage
• local/project/global skills CLI flow at the code level
• current CI status

The blocker I raised is fixed on the current head. Skill names are normalized before path construction, cleanup now removes the explicit temp root, install targets are resolved under the intended skills root, and the new regression tests cover the unsafe raw-markdown and registry-name cases.

Local verification I ran:

• bun test src/cli/handlers/skills.test.ts src/skills/loadSkillsDir.test.ts src/commands.test.ts
• bun run build
• bun run smoke
• git diff --check

All passed. I do not see a remaining blocker from my side for this PR scope.

Small non-blocking note: colon namespace skill names may be awkward as literal install folder names on Windows, but that is not the same safety issue and can be handled separately if it becomes a UX problem.

[Vasanthdev2004]

good for me @anandh8x we just need to test all 3 now

[Vasanthdev2004]

Pushed a maintainer follow-up onto this branch to get it current with main and tighten the install-side trust boundary.

What changed:

• resolved the main merge conflicts; PR is mergeable again
• registry installs now require a sha256 pin and refuse unpinned registry entries
• registry installs still verify the downloaded SKILL.md content against the registry hash before writing anything
• min_openclaude_version is enforced at install time
• tools_required and min_openclaude_version are preserved into installed skill.json
• non-official/non-standard trust tiers now print a warning during install

What I intentionally did not add here:

• session-start revocation checks
• runtime tool permission prompts
• trust promotion governance

Those are bigger runtime/governance pieces and should land as focused follow-ups after this local skills CLI foundation is merged.

Verification run locally:

• bun test src/cli/handlers/skills.test.ts src/skills/loadSkillsDir.test.ts
• bun test src/utils/conversationArc.perf.test.ts src/utils/knowledgeGraph.stress.test.ts src/utils/providerProfile.test.ts
• bun run build
• bun run smoke

Note: bun run lint no longer exists on current main. bun run typecheck still fails with broad existing repo type errors unrelated to this PR, so I did not treat that as a blocker for this branch.

[gnanam1990]

Maintainer review of the local Skill Hub CLI slice. I focused on the OpenClaude red-flag surface (network egress, config-path resolution, traversal safety) and treated @Vasanthdev2004's prior install-path review as the deep dive on the install boundary rather than re-deriving it.

Verdict: Approve — non-blocking follow-up requested.

What I independently verified on the current head:

• Path traversal is genuinely closed: VALID_INSTALL_SKILL_NAME + resolveContainedPath() (relative + .. check) run before any join/rm/cp, temp cleanup targets an explicit tempRoot (not dirname(tempDir)), and there is regression coverage for ../escape from both raw SKILL.md and registry metadata.
• Network egress is acceptable: fetch() only runs in the explicit skills install registry path (lazy-imported subcommand), never on startup and never in the provider/third-party routing path, and it points at the Gitlawb-owned registry — not an Anthropic/telemetry surface. sha256 pin is mandatory, content is verified before write, min_openclaude_version is enforced, and non-official trust tiers warn.
• The envUtils.ts change is behavior-preserving: migrateLegacyClaudeConfigHome already early-returns when CLAUDE_CONFIG_DIR is set, so old and new paths resolve identically; the refactor only fixes memoization so a stale default can't mask CLAUDE_CONFIG_DIR (needed for skills install --global). No silent config regression.
• No tengu_*/fingerprint introduced (the one tengu_ line in the diff is unchanged context), no hardcoded tokens, no CI/workflow diffs.

Non-blocking, please address before/at merge:

1. The PR description says registry install is "intentionally left for follow-up PRs", but skillsInstall.ts fully implements it including the first network egress for this feature. Please update the summary so the registry-install + network behavior is actually disclosed to anyone reading the PR.
2. conversationArc.perf.test.ts, knowledgeGraph.stress.test.ts, and providerProfile.test.ts are unrelated CI-stabilization changes bundled into a feature PR — fine to ride here since they were needed for green CI, just calling out the scope.

Good direction and a solid foundation for the Skill Hub. Approving the code; please tidy the description.

Findings

• [P2] Local directory installs flatten nested skill namespaces
  src/cli/handlers/skillsInstall.ts:315-332
src/skills/loadSkillsDir.ts:644-650
  For directory sources, the installer derives the installed name from basename(sourcePath). That breaks any nested skill package whose command name is supposed to come from its path segments. A source directory like repo/git/commit/ now installs into .openclaude/skills/commit, and the loader will expose it as commit, not git:commit. I reproduced this locally with a valid nested skill directory: the handler printed Installing skill "commit" and created only skills/commit. Raw SKILL.md installs preserve names from frontmatter, but the directory install path silently renames nested skills.

• [P2] The new precedence isolation test is not actually green on Windows
  src/skills/loadSkillsDir.test.ts:164-205
  This test now isolates state by spawning a standalone child process with process.execPath and asserting it exits successfully. In my focused Windows run, that child process exits nonzero before the assertion because importing the source tree in that context fails while resolving src/utils/permissions/yoloClassifier.ts prompt assets (./yolo-classifier-prompts/auto_mode_system_prompt.txt). The rest of the touched tests pass, but this specific new test does not, so the PR's advertised focused validation is not portable yet.

[jatmn]

Thanks for following up on the earlier review. The local directory install namespace issue looks addressed now, and the Windows-focused loader test is green in my rerun.

No issues here, LGTM.

Review summary

Thanks for the continued hardening here. The current head looks solid on the earlier install-path and namespace issues, but I found one remaining blocker around the new local skills CLI commands being coupled to provider startup validation.

Findings

• src/entrypoints/cli.tsx:141 - skills CLI commands still require valid provider startup state.
  Impact: The PR adds local/script-friendly skills management commands, but the entrypoint still runs validateProviderEnvForStartupOrExit() before dispatching skills list/show/validate/install/remove. In non-TTY/script usage, invalid provider env exits before the handler runs, so users cannot inspect or manage local skills until unrelated provider configuration is fixed.

  I reproduced this against the built CLI:

  CLAUDE_CODE_USE_OPENAI=1 OPENAI_BASE_URL=https://api.openai.com/v1 OPENAI_API_KEY= node dist/cli.mjs skills list

  That exits 1 with the OpenAI missing-key error instead of listing local skills.

  Suggested fix: Fast-path args[0] === 'skills' before provider profile hydration/validation, or make startup provider validation skip these local management subcommands. Please also add an entrypoint-level regression test for skills list with invalid provider env and redirected stdout.

Validation

• bun test src/cli/handlers/skills.test.ts src/skills/loadSkillsDir.test.ts src/commands.test.ts
• bun run build
• Reproduced the blocker with built dist/cli.mjs
• bun run security:pr-scan did not reveal a current-head PR blocker from the refreshed diff

[anandh8x]

Addressed the final review blocker in commit 732be43.

Changes made:

• Routed skills CLI commands before provider profile hydration/startup validation so local skills management still works when provider env is broken.
• Handles supported leading global flags before skills, including openclaude --bare skills list.
• Added entrypoint regression coverage for both skills list and --bare skills list with invalid OpenAI env.
• Kept local runtime folders like .omx/ and .codex/ out of the commit.

Verification:

• bun test src/entrypoints/cli.skills.test.ts src/cli/handlers/skills.test.ts src/skills/loadSkillsDir.test.ts src/commands.test.ts
• bun run build
• CLAUDE_CODE_USE_OPENAI=1 OPENAI_BASE_URL=https://api.openai.com/v1 OPENAI_API_KEY= node dist/cli.mjs skills list
• CLAUDE_CODE_USE_OPENAI=1 OPENAI_BASE_URL=https://api.openai.com/v1 OPENAI_API_KEY= node dist/cli.mjs --bare skills list
• bun run smoke

GitHub Actions are passing on the latest run: smoke-and-tests and web.

[Vasanthdev2004]

Targeted re-review of the current head (732be43), focused on the latest startup-validation blocker plus the Skill Hub install/trust boundary.

Verdict: Approve-ready

What I rechecked:

• skills CLI commands now dispatch before provider profile hydration/startup validation, so local skills management still works when provider env is broken.
• openclaude skills list and openclaude --bare skills list both work with invalid OpenAI env in the built CLI.
• install path hardening is still intact: names are normalized before path construction, colon namespaces install as nested paths, temp cleanup uses the explicit temp root, and target paths resolve under the selected skills root before overwrite/copy.
• registry installs require sha256, verify downloaded SKILL.md before writing, preserve tools_required / min_openclaude_version, and enforce the OpenClaude version gate.
• no hidden/bidi characters found in changed files, and the PR intent scan is clean.

Verification I ran locally:

• bun test src/entrypoints/cli.skills.test.ts src/cli/handlers/skills.test.ts src/skills/loadSkillsDir.test.ts src/commands.test.ts
• bun test src/utils/conversationArc.perf.test.ts src/utils/knowledgeGraph.stress.test.ts src/utils/providerProfile.test.ts
• bun run build
• bun run smoke
• bun run security:pr-scan -- --base origin/main
• git diff --check origin/main...HEAD
• manual built-CLI checks for skills list and --bare skills list with broken OpenAI env

I do not see a remaining code blocker on the current head.

One non-code cleanup before merge: the PR description is now stale. It still says registry install is left for follow-up, but this PR now implements registry install and introduces explicit registry fetch behavior. Please update the description so the merge record accurately discloses the current scope.

Blockers

None.

Non-Blocking

• PR description is stale — says registry install is left for follow-up, but this PR now implements it.

Looks Good

[kevincodex1]

bro please rebase and fix conflicts

[gnanam1990]

Thanks for the rebase and the focused follow-ups. I reviewed the three new commits against the standing blockers and they line up well:

• Provider independence (2e1bb06): getSkillsCliArgs() now fast-paths skills … into runSkillsCli before validateProviderEnvForStartupOrExit(), including handling of leading boolean/value flags. This addresses @techbrewboss's blocker — local skill management no longer requires valid provider env.
• Namespace preservation (c79a1d0): directory installs now resolve the name via getSkillNameFromDirectory() (SKILL.md frontmatter) and skillNameToInstallPath() maps git:commit → git/commit. This addresses @jatmn's flattening point for the common case.
• Path-traversal hardening (4ff411d): install/target paths still go through resolveContainedPath(), so the containment guard from the earlier review survived the rebase (@Vasanthdev2004's blocker).

Two things to confirm before this is fully clear:

1. The namespace fix relies on SKILL.md frontmatter carrying the namespaced name; getSkillNameFromDirectory() still falls back to basename(sourcePath), so a nested directory without a namespaced frontmatter name would still flatten. Is that the intended contract (frontmatter is the source of truth)? A short note/test for the fallback case would make it explicit.
2. loadSkillsDir.ts isn't touched by these commits — could you confirm the loader exposes the new nested install path (skills/git/commit) as git:commit end-to-end? @jatmn's original finding was two-part (installer + loader); the installer half is fixed, want to be sure the loader half resolves too.

One note on process: given the size (21 files / ~2.2k lines), I verified the three fix commits specifically rather than re-running the full suite in-session — worth confirming CI / bun test + bun x tsc --noEmit are green on the current head before merge. The targeted fixes look right; nice work.

[Vasanthdev2004]

Targeted re-review of the rebased current head (4ff411d), focused on whether the previously reviewed Skill Hub hardening survived the rebase.

Verdict: Approve-ready

What I rechecked:

• registry installs still require sha256 and verify the downloaded SKILL.md before writing anything
• min_openclaude_version is still enforced at install time
• tools_required and min_openclaude_version are still preserved into installed skill.json
• install path hardening survived the rebase: names are normalized before path construction, unsafe/path-like names are rejected, temp cleanup uses the explicit temp root, and target paths resolve under the selected skills root
• namespaced local installs like git:commit still install as nested paths and load back with the namespace intact
• skills CLI commands still bypass provider startup validation, including openclaude --bare skills list
• PR intent scan is clean and CI is green

Verification I ran locally:

• bun test src/entrypoints/cli.skills.test.ts src/cli/handlers/skills.test.ts src/skills/loadSkillsDir.test.ts src/commands.test.ts
• bun run build
• bun run smoke
• bun run security:pr-scan -- --base origin/main
• git diff --check origin/main...HEAD
• manual built-CLI checks for skills list and --bare skills list with broken OpenAI env

I do not see a remaining code blocker on the rebased head.

Non-blocking before merge: the PR description is still stale. It says registry install is left for follow-up, but this PR now includes registry install and registry network fetch behavior. Please update the body so the merge record matches the actual scope.
