sentinel-report

sentinel-report is a skill for Claude Code from Snowflake-Labs/cocoplus. It costs 31 tokens per session (527 once invoked), scanned A, original, MIT.

A report command that shows an artifact's evaluation history and whether it has been approved. An artifact is a project file or other item being checked.

In plain words
What is it for?
Use it to review Sentinel evaluations, compare approved and blocked results, and check approval dates and file fingerprints.
Why use it?
It gives you one place to see past evaluation outcomes and approval records before relying on an artifact.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sentinel-report scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Objective

You are generating a CocoSentinel evaluation history report for the current project.

Before proceeding, verify that .cocoplus/ exists. If not, output: "CocoPlus is not initialized. Run $pod init first." Then stop.

Step 1 — Collect Evaluation Results

Read all JSON files in .cocoplus/sentinel/ (excluding approvals.jsonl and active-evaluation.lock). Each file is a dimension evaluation result.

If no results exist, output: "No CocoSentinel evaluations found for this project. Run $sentinel <file> to evaluate an artifact." Then stop.

Step 2 — Collect Approvals

Read .cocoplus/sentinel/approvals.jsonl if it exists. Index by artifact_sha.

Step 3 — Build Report

For each evaluation result, cross-reference with approvals:

CocoSentinel Report — <project> — <current date>

Evaluations: <count>
  APPROVED:    <count>
  CONDITIONAL: <count>
  BLOCKED:     <count>

─────────────────────────────────────────────────────
Artifact                          SHA       Outcome     Approved
─────────────────────────────────────────────────────
<artifact_path>  <sha8>  APPROVED    Yes (2026-05-21)
<artifact_path>  <sha8>  CONDITIONAL Yes (with rationale)
<artifact_path>  <sha8>  BLOCKED     No
─────────────────────────────────────────────────────

Blocked Artifacts (require remediation):
  <artifact_path>: FAIL on dimensions [<list>]

Pending Approval:
  <artifact_path>: CONDITIONAL — BLOCKING concerns require developer rationale

Anti-Rationalization Table

Shortcut / Temptation Why It Fails
Skip SHA cross-reference for approvals Without SHA matching, approvals may reference stale artifact versions — silent false confidence
Omit CONDITIONAL artifacts from report Pending conditionals are the most actionable items — hiding them defeats the report's purpose

Exit Criteria

  • Report displays all evaluations with outcomes and approval status
  • Blocked artifacts are highlighted
  • Conditional artifacts awaiting approval are listed

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sentinel-report is a skill published in the GitHub repository Snowflake-Labs/cocoplus (720 stars, last pushed 6d ago), licensed MIT. It adds 31 tokens to every session and 527 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
