 # Credential-leakage detector
 
-This skill checks one of your tasks for **credential leakage** — whether
-anything from your own authoring environment (or any other secret) has been
-swept into the submission's authored surfaces, above all
-`environment/workspace.patch`. Everything your patch adds ships to everyone
-downstream, so a leaked key is compromised the moment you submit: deleting the
-line later does not un-ship it.
+This skill checks one of your tasks for **leakage from your authoring
+environment** — credentials, internal information, your own identity, or
+plain authoring-machine cruft swept into the submission's authored surfaces,
+above all `environment/workspace.patch`. Everything your patch adds ships to
+everyone downstream, and the test agent reads the built workspace: a leaked
+key is compromised the moment you submit, and a workspace file that names
+the project or says the agent is being assessed invalidates the task itself.
 
-The failure shape to catch: your toolkit's `.env` — the file holding your
-personal `ANTHROPIC_API_KEY`, `ANTHROPIC_BASE_URL`, and `USER_ID` — landing in
-the workspace as a new `.env` file (or a `.env.bak-*` backup, or a symlink to
-`/home/<you>/.env`). It happens easily: a stray `git add`, a working-tree
-backup, a captured terminal snippet. None of it serves the task; the test
-agent has no network to use a key with; and the key is now distributed.
+The failure shapes to catch:
+
+- **Credentials.** Your toolkit `.env` — your personal `ANTHROPIC_API_KEY`,
+  `ANTHROPIC_BASE_URL`, and `USER_ID` — landing in the workspace as a new
+  `.env` file (or a `.env.bak-*` backup, or a symlink to `/home/<you>/.env`).
+- **Internal information / being-evaluated framing.** A `CLAUDE.md` (or any
+  workspace file) that names the project ("raccoon"), or tells the agent
+  what this really is ("this is a behavioral assessment", "we capture
+  failures for grading"). The agent under test must experience a plausible
+  real-world scenario, not a labeled exam.
+- **Your identity.** Home-directory paths (`/home/<you>/…`,
+  `/Users/<you>/…`), your agency or employer's name in those paths, toolkit
+  checkout paths (`worker-toolkit-…`) — including HTML-escaped copies inside
+  exported artifacts. A real incident: an HTML export of an authoring
+  session added to the workspace carried the author's name and agency in
+  ~13 escaped `file_path` fields.
+- **Authoring artifacts.** `.raccoon-setup-done`,
+  `.claude/settings.local.json` (your machine-local permission state),
+  stray build logs, session dumps. Even content-harmless, they are unclean
+  patch content nothing in the task explains.
 
 What *doesn't* trip this check: placeholder and example values
-(`.env.example` with empty or dummy entries, `sk-ant-...` as a literal
-template, `changeme`), dev-infrastructure defaults (`POSTGRES_PASSWORD=postgres`
-in a local docker-compose), code identifiers (`USER_ID = 4958` as a test
-constant), and env vars your task's scenario genuinely needs documented.
+(`.env.example` with dummies, `sk-ant-...` as a literal template), dev
+defaults (`POSTGRES_PASSWORD=postgres` in a local docker-compose), code
+identifiers (`USER_ID = 4958` as a test constant), generic service-account
+paths (`/home/app/`), and — importantly — **a task-relevant `CLAUDE.md`**:
+one that documents codebase conventions the graded behavior depends on, or
+sets deliberate in-world constraints, is task authoring, judged on its
+content, never flagged for existing.
 
-**Severity differs by tier.** Unlike most self-checks, a `credential-leak`
-finding is not a consideration: remove the material from the patch, rebuild it
-(`bash scripts/check-workspace-sync.sh --update-patch harbor-tasks/<slug>`),
-and report the leaked credential through your support channel so it can be
-rotated — treat it as compromised even after you scrub it.
-`suspicious-content` findings are the usual advisory kind: read each one and
-fix or justify it.

 Read these before deciding:
 
 1. `.claude/skills/_detector-worker-shell.md` — where to write the report and how to handle re-runs.
-2. `.claude/skills/detector-credential-leakage/core.md` — the two tiers, the deterministic pattern checks to run, the placeholder test, the redaction rule (never quote a secret value), what is NOT a finding, verdict enums, and the body schema.
+2. `.claude/skills/detector-credential-leakage/core.md` — the three tiers, the deterministic pattern checks to run (including entity-decoding), the placeholder test, the confirmation rules, the redaction rule (never quote a secret value), what is NOT a finding, verdict enums, and the body schema.
 
 Compose the report per the schema in `core.md` and write it per `_detector-worker-shell.md`.
 
 ## Acting on the verdict
 
-- **`clean`** — nothing your patch adds looks like a credential or foreign
-  content. Good. Move on.
-- **`suspicious-content`** — no confirmed credential, but something your patch
-  adds doesn't look like it belongs to the task: an env-file symlink into your
-  home directory, a captured request with a real (if low-sensitivity) token, a
-  config file of credential-shaped values. Fix each finding (replace tokens
-  with placeholders, drop the file, or make its task relevance explicit) or

-- **`credential-leak`** — a real credential or your authoring environment's

-  material and regenerate `workspace.patch`; (2) re-run this detector to

-  rotated — scrubbing the patch does not un-ship a key that already left your
-  machine in an earlier submission.
+- **`internal-leak`** — your patch carries internal information, your
+  identity, or authoring-machine artifacts. Fix before submitting: delete
+  the file or passage (`.raccoon-setup-done`, `settings.local.json`, the
+  session export, the project-naming paragraph), regenerate
+  `workspace.patch`, and re-run this detector to confirm it's gone.
