scan-offensive

scan-offensive is a skill for Claude Code, Codex from nirecom/agents. It costs 23 tokens per session (1,130 once invoked), scanned A, original, MIT.

A tool that scans a GitHub repository's issues and comments for offensive language such as slurs, harassment, hate speech, or profanity. It produces a JSONL manifest, a file with one JSON record per finding, before any edits.

In plain words
What is it for?
Use it to scan selected issues or date ranges, review the findings, and redact confirmed items when the required manifest and identifiers are supplied.
Why use it?
It helps find harmful content already published while keeping redaction separate and confirmation-based.

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

scan-offensive 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/scan-repo.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/scan-offensive

Scan a GitHub repository's issues and comments for offensive content (hate speech, slurs, harassment, profanity). Produces a JSONL manifest; CC evaluates each item inline. Companion to the forward filter in hooks/scan-outbound.js, which blocks offensive content at write time.

Arguments

Flag Default Meaning
<owner>/<repo> current repo (gh repo view) Target repository
--dry-run on Produce manifest only; do not edit
--apply off Redact confirmed items (canary-gated; requires --manifest-path + --confirm-ids)
--since YYYY-MM-DD none Restrict to issues updated after this date (server-side)
--until YYYY-MM-DD none Restrict to issues updated before this date (client-side)
--from-issue N none Scan only issues numbered >= N
--to-issue N none Scan only issues numbered <= N
--manifest-out PATH stdout Write JSONL manifest to PATH instead of stdout
--manifest-path FILE — (with --apply) Path to previously produced manifest
--confirm-ids ID,... — (with --apply) Comma-separated item IDs to redact
--canary-skip off Skip canary stop; redact all confirmed IDs in one pass
--limit N none Stop after scanning N issues
--include-private off Also scan private repos (default skips them)

Procedure

Phase 1 — Produce manifest

  1. Resolve <owner>/<repo> from arguments or gh repo view --json owner,name.
  2. Invoke scripts/scan-repo.sh <owner>/<repo> [range flags] --manifest-out <tmp.jsonl>.
    • For large repos, use --since, --until, --from-issue, --to-issue to scan in batches of <= 100 items.
  3. Confirm the first line of <tmp.jsonl> has "type":"preamble" and "schema":"scan-offensive/skill-manifest/v1".

Phase 2 — Inline CC evaluation

  1. Read each item record from <tmp.jsonl>. For each record where "type":"item":
    • Extract the envelope field.
    • The body between <content> and </content> is the scanned issue/comment text.
    • Un-escape the body using the three-step inverse in this exact order: (1) &gt; → >, (2) &lt; → <, (3) &amp; → &.
    • Apply the classification rubric below to the un-escaped body.
    • Record a verdict tuple {id, verdict, reason}.
  2. Classification rubric:
    • block: hate speech (slurs, dehumanizing language targeted at a group), personal threats / calls to violence, sustained profanity directed at a person.
    • warn: borderline profanity, ambiguous hostility.
    • clean: no offensive content.
    • keyword_verdict: "hard" is a strong prior; verify the match is not quoted/contextual (e.g., CVE description quoting a slur, discussing the word itself).
    • keyword_verdict: "warn" is a weak prior; require semantic confirmation.
    • keyword_verdict: "clean" with no semantic match → verdict clean.
  3. Present findings (verdict ≠ clean) to the user with source URL.

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.
