+description: Check a Git repository's current candidate for high-confidence credential, private-key, and machine-home leaks, then perform a bounded public-release review. Use before publishing source or opening a public PR; do not use it to claim complete history or workflow-execution safety.

+
+# Public-Source Release Audit
+
+Use this skill to answer a narrow question honestly: does the current source
+candidate contain a supported high-confidence leak, and have the separate
+human and GitHub-native release checks been confirmed?
+
+## Automated Current-Source Check
+
+Run the repository's own verifier when it exists. Then run:
+
+```bash
+ruby <skill-directory>/scripts/check_current_source.rb <repository>
+```
+
+The checker reads exact Git-index blobs so an unstaged replacement cannot hide
+the candidate. It also scans tracked and non-ignored untracked worktree files
+for early feedback. It reports only paths and finding categories, never the
+matched content.
+
+The supported lexical forms are deliberately small:
+
+- PEM, OpenSSH, PGP, and PuTTY private-key headers;
+- GitHub `ghp_`, `gho_`, `ghu_`, `ghs_`, `ghr_`, and `github_pat_` token
+  prefixes;
+- AWS `AKIA`/`ASIA` access-key IDs and canonical named 40-character secret
+  access-key values;
+- OpenAI `sk-` and `sk-proj-` key prefixes;
+- explicit `Authorization: Bearer` header or map values; and
+- literal, commonly source-escaped, or `file://`-wrapped rooted POSIX families
+  `Users/<name>`, `var/root`, `private/var/root`, `home/<name>`, and `root`, plus
+  drive-letter `Users\\<name>` paths, including UTF-8 profile names and bounded
+  environment and command-option values.
+
+The home-path rule covers literal paths and common source escaping for POSIX
+slashes and Windows backslashes. It does not decode URL-encoded content. The
+credential map rules inspect direct source text; they do not decode nested
+escaped documents.
+
+Stage all intended release changes before relying on the candidate result.
+Ignored files and submodule contents are outside this check. The checker does
+not inspect Git history. Git LFS pointers fail the check because their external
+objects require separate review. Missing index blobs, including unavailable
+partial-clone objects, fail without network fetching. A symlink's own target
+text is scanned, while a symlinked parent component fails without reading
+outside the repository. Git's optional locks are disabled so read-only index
+operations do not freshen split-index metadata. BOM-marked UTF-16 source also
+requires separate review; the checker does not transcode or unpack content.
+
+## Semantic Review
+
+Automation cannot decide whether prose, filenames, images, or other assets
+contain customer information, internal links, personal data, or company-only
+context. Inspect the complete tree before first publication and the exact diff
+for later releases. Mark this check unconfirmed unless a reviewer actually
+performed it.
+
+## GitHub-Native Controls
+
+For an existing public GitHub repository, use read-only GitHub commands to
+confirm the live state rather than recreating GitHub policy logic locally:
+
+```bash
+gh repo view OWNER/REPO --json visibility,defaultBranchRef
+gh api repos/OWNER/REPO --jq '{visibility,security_and_analysis}'
+gh ruleset check --default --repo OWNER/REPO
+gh ruleset list --repo OWNER/REPO --parents --limit 100
+gh ruleset view RULESET-ID --repo OWNER/REPO
+default_branch="$(gh repo view OWNER/REPO --json defaultBranchRef \
+  --jq '.defaultBranchRef.name')"
+encoded_branch="$(ruby -rerb -e \
+  'print ERB::Util.url_encode(ARGV.fetch(0))' "$default_branch")"
+gh api "repos/OWNER/REPO/branches/${encoded_branch}/protection"
+gh api 'repos/OWNER/REPO/actions/runners?per_page=100' \
+  --jq '{total_count,runners:[.runners[] | {name,status,busy}]}'
+```
+
+Inspect applicable rulesets and classic branch protection when necessary to
+confirm the required hosted check, update strictness, and bypass actors. A 404
+from the classic endpoint means no classic rule is configured; it does not
+invalidate an applicable ruleset. If authorization cannot expose a setting,
+report it as unconfirmed. Do not weaken or mutate settings unless the user
+separately authorizes that action.
+
+## Result
+
+Report these fields separately:
+
+- repository verifier: `passed`, `failed`, or `not available`;
+- automated current-source check: `passed` or `failed`;
+- semantic context review: `confirmed` or `unconfirmed`;
+- GitHub-native controls: `confirmed`, `unconfirmed`, or `not applicable`;
+- history review: normally `not performed`;
+- bounded verdict: `ready` only when every check required for this release is
+  passed or confirmed.
+
+Do not summarize the bounded verdict as “the repository is safe.” Full-history
+investigation is a separate, exceptional workflow using established tooling.
+Publishing, rewriting history, revoking credentials, and changing repository
+settings remain separate actions requiring their own authorization.
