Summary

The openclaude skills commands have no page in docs/ and no mention in the README. This adds docs/skills.md and links it from the Setup Guides list.

The page covers:

  • the five commands and their flags, including --registry, --force, --global, and the two environment overrides;
  • what the registry install checks before it writes files: the sha256 pin, the revocations.json list from feat(skills): enforce registry revocations.json on install #2187, and the digest of the fetched SKILL.md;
  • URL installs with --sha256 and local path installs;
  • what the check does and does not cover. The digest runs once at install; the loader reads skill.json as metadata, and validate checks structure plus a few content patterns without comparing files to the registry digest, so a skill edited on disk after install loads unchanged. The transcript is from 0.30.0;
  • one section on checking installed skills after install with eyebrow, a separate MIT tool that hashes .openclaude/skills into a committed lockfile and reports drift and new egress hosts. I maintain eyebrow. The section is self-contained and can be dropped if you prefer the page without a third-party tool.

Impact

Documentation only. No code, no CLI change.

Testing

  • I ran the local preflight
  • Documentation only, so I ran the parts of the preflight that apply: bun run security:pr-scan -- --base FETCH_HEAD --head HEAD and node bin/openclaude --version.
  • Every command and output in the page was run against @gitlawb/openclaude@0.30.0 installed from npm in a fresh project.

Review follow-up

Four claims changed after review, each checked against @gitlawb/openclaude@0.30.0 and eyebrow 0.4.5 (7b839c6), with the symlink fix verified on 0.4.6 (6c1fbc5). Embedded commands were inspected as text, not run.

  • New-destination guarantee: now describes the 0.4.5 heuristic (literal HTTP(S) URLs on SKILL.md lines with curl, wget, secretcurl, or WebFetch) and states that other syntax and helper scripts are outside it. Observed: the curl line fails the policy with exit 1; a node -e "fetch(...)" line reports content drift and exits 0 under the same policy.
  • Hashing coverage: now states that a symlinked skill folder appears in the inventory with no hashed files in 0.4.5. Observed: a project skill symlink scans to the empty digest with no file list, and an edit to the target passes verify --ci with exit 0. This was an eyebrow defect, fixed in hash: resolve a symlinked root before walking alexverify/eyebrow#23 and released as 0.4.6, which hashes the linked contents; the guide now asks for 0.4.6 or newer and keeps the 0.4.5 note for readers on that version.
  • Local installs: now says the installer treats the source as local for that install and copies existing skill.json unchanged, so a later trust label may carry the source value. Observed in skillsInstall.ts: the candidate trust is set to local; the copy runs with fs.cp and no rewrite of the sidecar.
  • validate: now says it checks structure and a few content patterns and does not compare files to the registry digest. Observed in skillsValidation.ts: UNSAFE_TEXT_PATTERNS rejects a curl piped to a shell and credential collection text; a prose edit passes.

Summary by CodeRabbit

  • Documentation
    • Added a Skills guide covering openclaude skills commands for listing, viewing, validating, installing, managing, and removing skills.

The CLI guide fills a useful documentation gap. I found four accuracy issues in the descriptions of integrity checks and trust metadata: two overstate the protection readers get, and two describe existing behavior incorrectly. These can be addressed within the documentation scope of this PR.

This review covers 4e6a64438d90c42f157a88e2eaddaca8bbf35c88, with eyebrow behavior checked against release 0.4.5 (7b839c69af158578728dd24b41328072eff25f2e). The first-party implementation discussed below is unchanged from the PR base. The findings concern the new guide's claims about that behavior.

Merge readiness

The reviewed branch is current with the captured main revision, GitHub reports no conflicts, and all reported checks pass. GitHub reports BLOCKED; the captured branch rules require three approvals and approval of the latest push, while the current review state shows one CodeRabbit approval. This is separate from the documentation corrections below.

Findings

1. [P2] Qualify the new-destination guarantee

Location: docs/skills.md:96–99

The paragraph says the policy can allow wording edits and “still fail when a skill gains a new destination.” The curl example demonstrates one supported case, but that broader statement exceeds eyebrow 0.4.5's detection behavior.

The egress extractor looks for literal HTTP(S) URLs on SKILL.md lines containing curl, wget, secretcurl, or WebFetch. It does not determine all destinations that the skill or its helper scripts could contact. The verification policy permits content drift when allowContentDrift is enabled and no policy violation rejects it.

A concrete counterexample is:

  1. Scan an ordinary skill containing harmless instructions to establish a lockfile.
  2. Append this text to SKILL.md: Run: node -e "fetch('https://example.com/status')". This is fixture content to inspect; there is no need to execute the embedded command.
  3. Verify with --ci and the exact policy shown in the guide.

Verification reports content_changed but exits 0. The added destination produces no network capability delta. As a positive control, adding the guide's literal curl line produces the expected policy violation and exit 1.

Why this matters: a reader may enable the permissive policy believing that it distinguishes harmless wording changes from all newly introduced destinations. It distinguishes only the destinations recognized by that heuristic. This is an accuracy problem in the security guidance, even though the displayed curl example works.

Requested correction: describe the heuristic and qualify the guarantee. Keep the demonstrated curl example and policy if desired; this finding does not require changing the policy defaults or implementing broader egress detection.

For example:

In eyebrow 0.4.5, the egress fingerprint recognizes literal HTTP(S) URLs on SKILL.md lines containing curl, wget, secretcurl, or WebFetch. The policy below permits content drift and rejects newly recognized destinations. Other calling syntax and destinations inside helper scripts may not be detected, so this is not a general check for new network access.

2. [P2] Qualify hashing coverage for symlinked skill folders

Location: docs/skills.md:72

The paragraph says eyebrow records a hash of every skill it finds. In 0.4.5, a symlinked skill folder can be found and included in the lockfile without its instruction files being hashed.

The failure crosses several stages:

  • OpenClaude's loader follows skill-directory symlinks.
  • Eyebrow's discovery helper also recognizes a directory symlink as a skill.
  • Its local resolver preserves the symlink path.
  • Its directory hasher uses WalkDir and skips nonregular entries, so it does not traverse that root symlink.

For a project skill directory symlink pointing to a folder containing SKILL.md, scan creates a skill entry with no hashed files and the empty-content digest sha256-e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855. Appending harmless instructions to the target SKILL.md and running verify with --ci produces exit 0 and no drift, even without allowContentDrift.

Why this matters: the skill appears in the inventory, which gives the reader a concrete reason to believe it is covered. The issue is not a demand that the scanner discover every possible OpenClaude layout; this is a discovered skill whose content is not actually included in the advertised integrity check.

Requested correction: explicitly limit the hashing claim for this release. A short caveat is sufficient; fixing eyebrow or changing OpenClaude's symlink behavior is outside this PR's required remediation.

For example:

In eyebrow 0.4.5, symlinked skill directories can appear in the inventory without their contents being hashed. Do not interpret a clean verification result as an integrity check of those linked contents.

3. [P3] Distinguish install-time local treatment from persisted trust metadata

Location: docs/skills.md:46

The local-install paragraph correctly says that local sources bypass registry digest and revocation checks. However, it also says the skill is “recorded with trust local,” which is not guaranteed by the implementation.

The installer sets the temporary install candidate's trust to local and prints that label. It then copies the staged directory, including any existing skill.json, without rewriting that file's trust value. The loader reads the copied trust metadata.

For example, locally installing a copy of a skill whose sidecar contains "trust": "official" produces:

Install-time label: local
Persisted skill.json trust: official
Trust restored by the loader: official

Why this matters: the following section introduces list and show, including their trust output. Readers could infer that a local copy is durably marked as such, or that its displayed trust label proves registry-backed installation. The installer output alone does not establish either conclusion.

Requested correction: describe local treatment as an install-time decision and avoid promising a persisted provenance marker. Preserve the warning to review local sources independently. No trust-model or metadata-rewrite change is requested.

For example:

Local directory installs bypass registry digest and revocation checks and are treated as local during installation. Existing skill.json metadata is copied unchanged, so a later displayed trust label may retain the source directory's value. Review local sources independently.

4. [P3] Distinguish content-pattern checks from digest verification

Location: docs/skills.md:58

The sentence “validate checks structure, not content” is too absolute. The validator's unsafe-pattern definitions and per-file checking loop inspect supported text files and reject certain content patterns, including pipe-to-shell instructions, destructive commands, and credential collection.

A harmless prose edit passes, as shown in the guide. Adding a curl-pipe-shell instruction as text instead produces an unsafe-pattern validation error. The difference establishes that validation inspects some content; it does not establish comprehensive safety analysis or verification against the original digest.

Why this matters: the guide should accurately explain both the available check and its limitations. Denying the content checks understates existing behavior, while describing them as an integrity or safety guarantee would overstate it.

Requested correction: replace the structure-only description with the narrower distinction:

validate performs structural and heuristic content-pattern checks, but does not compare the installed files with the original registry digest.

Keep the harmless-edit example and the accurate explanation that normal loading does not automatically recheck the installed checksum. Also align the corresponding structure-only statement in the PR summary with the corrected guide.

Address the common cause in one documentation pass

These four findings share a documentation problem: the prose turns a narrower observation into a broader guarantee. A working curl example establishes that this curl line is detected; it does not establish general destination detection. A discovered skill establishes inventory membership; it does not prove the files were hashed. An install-time label does not prove that label survives persistence. A harmless edit passing validation does not mean validation never examines content.

That distinction explains how several accuracy findings can exist in a small documentation-only PR. It does not imply that the CLI guide lacks value or that its underlying tools must be redesigned. The existing examples can remain useful when the text states exactly what they demonstrate.

Please address the guide and its PR summary together, rather than making isolated substitutions only at the cited lines:

  1. Match each existing guarantee to its actual stage. For install claims, distinguish source selection, checking, copying, saved metadata, and later loading. For the external verification claims, distinguish discovery, hashing, lockfile storage, policy evaluation, and exit status. A successful earlier stage does not establish a later one.
  2. Keep observations and guarantees separate. Name the checked release when describing version-dependent third-party behavior. Use the existing successful examples to demonstrate supported cases, and add the specific limitations above where readers make a trust or policy decision.
  3. Verify the four corrected claims with small, harmless cases. Check the supported curl line versus unrecognized calling syntax; a regular skill folder versus the linked-folder case; install-time local output versus retained sidecar trust; and harmless prose versus a rejected content pattern. Inspect embedded commands as text—do not execute them. Existing evidence is sufficient if it accurately shows these results; a new permanent test suite is not a requirement of this docs change.
  4. Make one coherent follow-up. In the PR summary, state which claims changed, the versions checked, and the observed results. Ensure the introduction, examples, limitations, and summary no longer make contradictory assertions. This makes the correction assessable as a whole rather than requiring another round to discover what an individual wording change implies.

The acceptance target is bounded: accurately describe the behavior behind these four claims. Expanding the guide into an exhaustive support matrix, adding global or nested-skill tutorials, changing runtime trust handling, replacing the demonstrated policy, and implementing new scanner capabilities are not required to resolve this review. Any separately desired implementation work should be discussed on its own merits.

2. [P2] Qualify hashing coverage for symlinked skill folders

Location: docs/skills.md:72

The paragraph says eyebrow records a hash of every skill it finds. In 0.4.5, a symlinked skill folder can be found and included in the lockfile without its instruction files being hashed.

The failure crosses several stages:

  • OpenClaude's loader follows skill-directory symlinks.
  • Eyebrow's discovery helper also recognizes a directory symlink as a skill.
  • Its local resolver preserves the symlink path.
  • Its directory hasher uses WalkDir and skips nonregular entries, so it does not traverse that root symlink.

For a project skill directory symlink pointing to a folder containing SKILL.md, scan creates a skill entry with no hashed files and the empty-content digest sha256-e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855. Appending harmless instructions to the target SKILL.md and running verify with --ci produces exit 0 and no drift, even without allowContentDrift.

Why this matters: the skill appears in the inventory, which gives the reader a concrete reason to believe it is covered. The issue is not a demand that the scanner discover every possible OpenClaude layout; this is a discovered skill whose content is not actually included in the advertised integrity check.

Requested correction: explicitly limit the hashing claim for this release. A short caveat is sufficient; fixing eyebrow or changing OpenClaude's symlink behavior is outside this PR's required remediation.

For example:

3. [P3] Distinguish install-time local treatment from persisted trust metadata

Location: docs/skills.md:46

The local-install paragraph correctly says that local sources bypass registry digest and revocation checks. However, it also says the skill is “recorded with trust local,” which is not guaranteed by the implementation.

The installer sets the temporary install candidate's trust to local and prints that label. It then copies the staged directory, including any existing skill.json, without rewriting that file's trust value. The loader reads the copied trust metadata.

For example, locally installing a copy of a skill whose sidecar contains "trust": "official" produces:

Install-time label: local
Persisted skill.json trust: official
Trust restored by the loader: official

Why this matters: the following section introduces list and show, including their trust output. Readers could infer that a local copy is durably marked as such, or that its displayed trust label proves registry-backed installation. The installer output alone does not establish either conclusion.

Requested correction: describe local treatment as an install-time decision and avoid promising a persisted provenance marker. Preserve the warning to review local sources independently. No trust-model or metadata-rewrite change is requested.

For example:

Local directory installs bypass registry digest and revocation checks and are treated as local during installation. Existing skill.json metadata is copied unchanged, so a later displayed trust label may retain the source directory's value. Review local sources independently.

4. [P3] Distinguish content-pattern checks from digest verification

Location: docs/skills.md:58

The sentence “validate checks structure, not content” is too absolute. The validator's unsafe-pattern definitions and per-file checking loop inspect supported text files and reject certain content patterns, including pipe-to-shell instructions, destructive commands, and credential collection.

A harmless prose edit passes, as shown in the guide. Adding a curl-pipe-shell instruction as text instead produces an unsafe-pattern validation error. The difference establishes that validation inspects some content; it does not establish comprehensive safety analysis or verification against the original digest.

Why this matters: the guide should accurately explain both the available check and its limitations. Denying the content checks understates existing behavior, while describing them as an integrity or safety guarantee would overstate it.

Requested correction: replace the structure-only description with the narrower distinction:

validate performs structural and heuristic content-pattern checks, but does not compare the installed files with the original registry digest.

Keep the harmless-edit example and the accurate explanation that normal loading does not automatically recheck the installed checksum. Also align the corresponding structure-only statement in the PR summary with the corrected guide.

Address the common cause in one documentation pass

These four findings share a documentation problem: the prose turns a narrower observation into a broader guarantee. A working curl example establishes that this curl line is detected; it does not establish general destination detection. A discovered skill establishes inventory membership; it does not prove the files were hashed. An install-time label does not prove that label survives persistence. A harmless edit passing validation does not mean validation never examines content.

That distinction explains how several accuracy findings can exist in a small documentation-only PR. It does not imply that the CLI guide lacks value or that its underlying tools must be redesigned. The existing examples can remain useful when the text states exactly what they demonstrate.

Please address the guide and its PR summary together, rather than making isolated substitutions only at the cited lines:

  1. Match each existing guarantee to its actual stage. For install claims, distinguish source selection, checking, copying, saved metadata, and later loading. For the external verification claims, distinguish discovery, hashing, lockfile storage, policy evaluation, and exit status. A successful earlier stage does not establish a later one.
  2. Keep observations and guarantees separate. Name the checked release when describing version-dependent third-party behavior. Use the existing successful examples to demonstrate supported cases, and add the specific limitations above where readers make a trust or policy decision.
  3. Verify the four corrected claims with small, harmless cases. Check the supported curl line versus unrecognized calling syntax; a regular skill folder versus the linked-folder case; install-time local output versus retained sidecar trust; and harmless prose versus a rejected content pattern. Inspect embedded commands as text—do not execute them. Existing evidence is sufficient if it accurately shows these results; a new permanent test suite is not a requirement of this docs change.
  4. Make one coherent follow-up. In the PR summary, state which claims changed, the versions checked, and the observed results. Ensure the introduction, examples, limitations, and summary no longer make contradictory assertions. This makes the correction assessable as a whole rather than requiring another round to discover what an individual wording change implies.

The acceptance target is bounded: accurately describe the behavior behind these four claims. Expanding the guide into an exhaustive support matrix, adding global or nested-skill tutorials, changing runtime trust handling, replacing the demonstrated policy, and implementing new scanner capabilities are not required to resolve this review. Any separately desired implementation work should be discussed on its own merits.

All four confirmed and corrected in one pass, and the PR summary now lists each changed claim with the versions checked and the observed results.

The symlink case was an eyebrow defect: the hasher did not resolve a symlinked root, so the folder was listed with the empty digest. Fixed in eyebrow#23 and released as 0.4.6, which hashes the linked contents. The guide now asks for 0.4.6 or newer and keeps the 0.4.5 note.

Checked against openclaude 0.30.0, with the embedded commands inspected as text.

Thanks for the iterative work on this guide. The four corrections from the prior review round are materially better on ae9b2e0: local-install trust metadata, validate vs digest, eyebrow egress/symlink boundaries, and verify exit codes all read like checked observations now. I do not think this PR needs another wide documentation pass or a growing issue list.

What remains is one consistency defect inside the page, plus optional clarity on an installer edge case. Everything else reviewers (including me) surfaced during this pass is either pre-existing runtime behavior outside this PR’s scope, or exhaustive error-catalog material that would turn a CLI guide into an implementation spec. I am not asking you to chase those.

Below: why the review cycle has felt endless, how to close it in one edit, then the actual findings.


Why this PR keeps getting review rounds

This is not a sign the guide is low value. It is a predictable outcome of what the page documents.

1. The subject is trust-boundary documentation.

openclaude skills install is a security-sensitive surface: registry digest pins, revocation lists, local bypass, post-install tampering, and a third-party lockfile workflow. Any skills guide will be read as security guidance, not just command reference. Reviewers therefore probe every sentence for “does this overstate what the user gets?” That is the same defect class jatmn flagged in the first round: a narrower observation turned into a broader guarantee.

2. The page describes four different systems with one voice.

Readers (and reviewers) must mentally separate:

Layer What it checks When
Registry install sha256 pin, revocations, digest of fetched SKILL.md Once, at install, registry id path only
URL / local install digest pin (HTTPS only) or nothing Once, at install
openclaude skills validate Structure, size limits, heuristic content patterns On demand; no registry digest compare
Runtime load Reads skill.json metadata; loads folder contents Every session / hot reload
eyebrow Lockfile hash + optional egress policy External; version-specific

When prose in one section uses the vocabulary of another (“checks,” “integrity,” “trust,” “validates”), contradictions appear even when each sentence is locally defensible. That is the root cause of drip review: fixes applied line-by-line at cited locations without a whole-page pass using the table above.

3. Prior rounds fixed symptoms in the right sections but not every mirror of the same contract.

The validate correction landed in “What the install check covers” (line 58) but not in the command summary (line 54). That pattern—patch the paragraph a reviewer cited, leave synonymous wording elsewhere—is exactly what produces “one more finding” on the next pass. It is not malice or nitpicking; it is an incomplete application of the same rule.

4. Scope creep pressure from adjacent surfaces.

OpenClaude also loads plugin skills, MCP skills, conditional paths skills, ancestor project dirs, and config-home overrides. A maximalist reviewer can always ask for those in this page. They do not belong here unless the guide already claims universal coverage. Your opening line is scoped to .openclaude/skills and the openclaude skills commands; keep that scope explicit and do not let drive-by review comments expand the guide into a loader architecture doc.

5. eyebrow invites version-pinned scrutiny.

The eyebrow section is useful and appropriately caveated now (0.4.5 vs 0.4.6, heuristic egress limits). It will always attract third-party tool review. Treat it as a self-contained optional appendix: if maintainers ever want it removed, the page still stands. Do not merge eyebrow claims into OpenClaude guarantees.


How to close this in one pass (acceptance criteria)

Do one editing pass with these rules. If you follow them, I do not expect another documentation-finding round from this angle.

Rule A — Stage every claim before you write it

For each sentence that uses “check,” “verify,” “validate,” “trust,” or “integrity,” label internally:

  • Which command or tool? (install registry / install URL / install local / validate / runtime load / eyebrow)
  • Which stage? (select source → pre-write checks → copy to disk → later load → external scan)
  • Observation or guarantee? An example that worked once is an observation; “always” / “every” / “refuses” is a guarantee.

A guarantee must be true for all code paths the sentence implies. If it is true for only one path, name that path in the same sentence or split into two bullets by install source.

Rule B — One contract, one wording everywhere

If line 58 says validate inspects content patterns, line 54 must not imply structure-only. Same for any future edits: grep the file for validate, trust, revocation, digest, check and align every hit.

Rule C — Do not expand scope to satisfy reviewers

Explicitly out of scope for this PR (do not add sections for these; linking to advanced setup or source is enough):

  • Full loader discovery (plugins, MCP, managed policy, ancestor dirs, conditional skills)
  • Every installer error path (revocation HTTP 500, malformed JSON, min_openclaude_version, file:// URLs)
  • OPENCLAUDE_CONFIG_DIR (the page correctly says “your user skills directory,” not ~/.openclaude/skills)
  • Rewriting installer precedence or trust persistence in code

Rule D — Verify with the same four harmless cases jatmn listed

After editing, re-check (inspect as text; no need to execute embedded commands):

  1. Registry id install when registry path is actually taken (network/registry checks run).
  2. Local directory install: install-time Trust: local vs persisted skill.json trust if sidecar says official.
  3. Harmless SKILL.md prose edit: validate passes; no digest re-check on load.
  4. curl … | sh as text in SKILL.md: validate rejects.

Update the PR summary once with: what changed, what you re-checked, what you intentionally left out of scope.

Done when

  • No contradictory statements between intro, command summary, detailed sections, and examples for the two findings below.
  • PR summary matches the file.
  • Rebased on current main (see merge readiness).

Merge readiness

  • Rebase onto current main. Head ae9b2e0 is three commits behind live 0abfca30. The three-dot diff is still docs-only; rebase is process hygiene per CONTRIBUTING, not a content finding.

  • Approval policy. GitHub reports BLOCKED (three approvals required; CodeRabbit has approved ae9b2e0). After the doc fix below, this needs a maintainer re-review of the corrected head—not another automated broad scan.


Findings

1. [P3] validate wording is inconsistent within the same page

Location: docs/skills.md:54 vs docs/skills.md:58

What is wrong

Line 54 (command summary):

validate <path> checks a skill directory before you publish it: the frontmatter fields, the skill name, and the file size limits.

Line 58 (integrity section):

validate checks structure and rejects a few content patterns, such as a curl piped to a shell or a credential collection instruction, but it does not compare the installed files with the registry digest.

Both describe the same CLI command. Line 58 matches the implementation; line 54 does not.

Implementation (unchanged on this branch)

skillsValidateHandler calls validateSkillPath(path) with default options—no registry digest comparison (skills.ts ~178–179). skillsValidation.ts applies UNSAFE_TEXT_PATTERNS (e.g. curl pipe-to-shell, credential-collection phrasing) across supported text files (~29–40, ~195–205). Registry-only required metadata (title, trust, etc.) is enforced only when requireRegistryMetadata: true at registry install time, not standalone validate (~160–167, skillsInstall.ts ~740–742).

Root cause

The prior review asked to distinguish structure-only language from content-pattern checks. The fix was applied in the detailed integrity section but not in the command summary—classic staged-contract drift inside one file.

What to do (smallest fix)

Replace the validate clause on line 54 so it matches line 58’s distinction. For example:

validate <path> checks structure, file size limits, and a few heuristic content patterns (such as pipe-to-shell instructions), but does not compare files to a registry digest.

Do not add registry metadata requirements to standalone validate; that would be scope drift and misdocument behavior.

How to prevent recurrence

After editing line 54, search the file for validate and structure and confirm no other sentence implies validate is structure-only.


2. [P3] Registry install section does not mention installer path precedence (optional but recommended)

Location: docs/skills.md:18–30

What is wrong (nuanced)

The registry section accurately describes what happens when the registry branch runs: sha256 required, revocations consulted, digest verified. It does not mention that the installer checks local filesystem existence first.

In prepareInstallCandidate (skillsInstall.ts ~615–657), any non-URL spec where resolve(spec) already exists is treated as a local install (registryBacked: false) before registry resolution (~688+). So openclaude skills install gitlawb/ci-fix with a present relative tree gitlawb/ci-fix/ copies locally with no registry fetch, digest check, or revocation check, and prints Trust: local.

I reproduced this on ae9b2e0 with a scratch gitlawb/ci-fix/SKILL.md tree.

This is not a bug in your PR—the installer behaved this way before docs/skills.md existed. It becomes a documentation issue only because the guide teaches registry install using an id that can double as a relative path.

Severity note

This is an edge case (cwd must contain a colliding path). Line 46 already warns that explicit local installs skip registry checks. I am not elevating this to P2. Include a caveat only if you want the registry section to be airtight against misinterpretation.

Root cause

The guide describes registry checks as properties of the command example (install gitlawb/ci-fix) rather than as properties of the registry code path. Those differ when spec resolution hits disk first.

What to do (one sentence, if you include it)

After the numbered registry checks (or in Options), add something like:

If the install spec resolves to an existing file or directory in the working tree, the installer treats it as a local install and does not run registry digest or revocation checks, even when the spec looks like a registry id.

Do not ask for installer reordering in this docs PR—that would be product drift.

How to prevent recurrence

When documenting any install source, name the condition under which that source’s checks run (“when the registry branch is taken”), not only the happy-path example.


What I am explicitly not asking for

To stop review drip, treat the following as closed / out of scope unless you introduce new claims about them:

Topic Why not a finding here
Revocation list HTTP 500 / malformed JSON fail-closed Accurate omission, not overclaim; operator detail belongs in registry ops docs if anywhere
OPENCLAUDE_CONFIG_DIR Page says “user skills directory,” not ~/.openclaude; not wrong
URL install skipping revocations Doc scopes revocations to registry section; URL section describes digest pin
list transcript missing table header Cosmetic example shortening
Plugin/MCP/bundled skills in list Loader scope; page is about openclaude skills install surface
min_openclaude_version, file:// installs, hot reload vs “next run” Implementation detail; page does not claim to cover them
eyebrow behavior beyond current caveats External tool; section is already version-qualified

If you add any of the above voluntarily, keep them to short caveats and apply Rule A so they do not contradict existing text.


Summary for the author

The guide is close. The repeated review cycles come from trust-boundary prose edited in fragments across a page that spans multiple independent check stages. The fix is not more examples or broader coverage—it is one whole-file consistency pass using stage separation (install vs validate vs load vs eyebrow), then stop.

Required: align line 54 with line 58 for validate.

Optional: one-sentence registry path-precedence caveat.

Process: rebase, update PR summary with re-check notes, request maintainer re-review.

That should be the last documentation-finding round for this PR from this reviewer.

thank you @jatmn for the review.

Both applied. The validate summary now matches the integrity section, and the registry section states that its checks run only on the registry path, with the local path taken first when the spec names an existing directory. A whole page pass with the same rule fixed three more sentences: the eyebrow path, the revocation match rule, and the validate checks on local installs. Ran your four cases against 0.30.0. Rebased onto main.
