audit

audit is a skill for Claude Code from nagisanzenin/idiolect. It costs 57 tokens per session (685 once invoked), scanned A, original, MIT.

A two-part check for signs that text was written by an AI. It combines a rule-based scan with a separate human-like reading of the text.

In plain words
What is it for?
Use it to review text for AI-like patterns, see the lines that trigger concern, and get suggestions for making the writing sound more natural.
Why use it?
It helps identify specific wording, structure, or tone that makes writing feel machine-generated, instead of giving only a vague verdict.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: mentions subagents; mentions Codex; $skill-name invocation.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

audit 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 43 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/idiolect:audit — where the mask slips

Two independent layers, merged into one report. The scanner catches what regex can see; the blind judge catches what only reading can (no stakes, hollow specificity, symmetric enthusiasm, tutorial cadence). Neither layer knows or cares who wrote the text.

Setup

ROOT="${CLAUDE_PLUGIN_ROOT:-${CODEX_PLUGIN_ROOT:-$IDIOLECT_ROOT}}"
# unset everywhere (opencode)? ROOT = two directories up from this SKILL.md
IDIO="python3 $ROOT/scripts/idiolect.py"

Flow

  1. Save the text to a scratch file. Run $IDIO scan --file <f> --json [--platform <p>].

  2. Spawn the blind judge — the idiolect-auditor agent — passing ONLY: the text (via the scratch file path), the platform if known, and nothing else. No authorship context, no "the user thinks this is AI," no scanner results (independence is the point; two correlated judges are one judge). On Codex, invoke it explicitly: $idiolect-auditor, audit this file: <path>. If subagent spawning is unavailable, do the semantic pass yourself in a deliberately separate step, AFTER writing down the scanner results, using the auditor's rubric (read $ROOT/agents/idiolect-auditor.md).

  3. Merge into the report:

    verdict: 62/100 — reads generated (scanner 58 · judge: generated-leaning)
    deterministic tells (line-anchored):
      L3  "seamlessly integrates" (lexical T1)
      L7  its_not_x_its_y construction
      —   sentence lengths metronomic (CV 0.31; human ≥ 0.5)
    semantic tells (judge):
      - zero cost or stake attaches to any claim
      - enthusiasm is symmetric across all six sentences
    human texture present: 1 exact number; no temporal anchors, no first-person actions
    top 5 fixes, in order of impact: ...
    
  4. Frame it honestly, always: this is a linter verdict about how the text reads, not a forensic finding about how it was made. Skilled humans trip tells; edited AI passes. Never output "this was written by AI" — output "these N things make it read generated, here's the fix for each." If the user is auditing someone ELSE's text to accuse them (a student, an employee), say plainly: no tool can prove authorship from style, false-positive rates hit non-native writers hardest (Liang et al. 2023), and this report must not be used as evidence against a person.

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.
