voice-critic

voice-critic is a skill for Claude Code, Codex from petar-djukic/writing-skills. It costs 0 tokens per session (1,460 once invoked), scanned A, original, MIT.

A read-only review workflow for checking whether writing matches a defined personal voice, including stance, tone, recurring language patterns, and snark. Read-only means it reports issues without changing the document.

In plain words
What is it for?
Use it to review a draft against a voice constitution and language profile, receive flagged passages, and audit the level and density of snark.
Why use it?
It catches writing that sounds unlike the author or that pushes a stylistic device too far before publication.

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

voice-critic 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 7d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/test_voice_critic.py, scripts/voice_critic.py), 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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.


name: voice-critic description: >- Cold, read-only gatekeeper against writing-voice/voice-constitution.md: five per-dimension verdicts with flagged spans — stance, theory-of-mind device, disproportion (locked-span check), computed marker profile against idiolect targets, and a snark audit on the constitution's L0-L5 scale with receipt-first, safe-enemy, and per-form density-cap hard rules. Never edits; flags route to the author gate. Triggers: voice critic, does this sound like me, snark audit, constitution check, voice gate, critique voice, off-voice check.

Voice Critic (read-only gatekeeper)

filter-tells detects "sounds like a machine". This critic detects two different failures: "doesn't sound like Petar" and "went too far". The rubric is writing-voice/voice-constitution.md — discovered by the standard walk-up, refused when absent, because the critic's taste is that file, not anything built in. Rates come from idiolect.yaml, the single source of truth the constitution itself defers to.

Read-only is the contract. scripts/voice_critic.py takes a document and produces a report; it never modifies the input, and the tests assert input bytes unchanged. That is why it may run after the terminal inject-vernacular stage — its home is the caller's review phase (GH-208), after critic-panel — and equally at any earlier gate; nothing in it assumes pipeline position. It is not a stage of the humanize chain.

The critic flags; the author adjudicates. It replaces self-monitoring with a checklist, not with enforcement: over-ceiling snark is flagged, never auto-deleted, and every flag carries the quoted span and line range so the gate read is a yes/no per item.

The five dimensions

dimension how what it asks
stance judged Expert-watching, curiosity not contempt (§1)? At the bench, not the balcony?
tom-device screened + judged Model stated → predictions derived → tested against the artifact (§2)? The deterministic screen finds candidate evidence for each of the three parts; the judge (or the author) says whether the device is executed.
disproportion computed One declared overrun present and protected? Span locks are the declaration mechanism, so this reads the drivers' lock report.
marker-profile computed, never judged idiolect.yaml regex rates against essay targets, ±30% tolerance — the same arithmetic inject-vernacular applies as operators, run here as a check.
snark-audit judged instances, computed rules Every instance scored L0–L5; then the three hard rules run mechanically over the instances.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

voice-critic is a skill published in the GitHub repository petar-djukic/writing-skills (4 stars, last pushed 8d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,460 tokens. 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 2026-08-31.
