A documentation checker that finds highly similar Markdown files and broken internal links. Markdown is a plain-text format commonly used for project documentation.

Use it to check documentation for duplicates, broken references, or invalid relative links.

It helps detect repeated documents and references to files that no longer exist, while ignoring code and external links.

censor — Skill for Claude Code by bestdeejay-design

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add bestdeejay-design/agent-skills --skill censor

Clone the repo

git clone --depth 1 https://github.com/bestdeejay-design/agent-skills

Made for: Claude Code.

Per session 65 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 393 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00065	$0.00393
Opus 5	$0.00032	$0.00197
Sonnet 5	$0.00013	$0.00079
Haiku 4.5	$0.00006	$0.00039

Measured 7d ago against content hash 96a268bdaf25, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

censor 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.

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.

What it actually says

Censor — Fact-Checker

Detects duplicate documents and broken internal links in markdown documentation.

What it does

Duplicates — finds documents with similarity above threshold (default 70%)
Broken links — validates relative markdown links; skips code blocks, inline code, external URLs (http/https/mailto)

Usage

# Via Chronos orchestrator
chronos --path . --preset minimal

# Direct invocation
python -m chronos.agents.censor --path .

Output Format

[warning] duplicate: High similarity (85%) with docs/ROADMAP.md
[warning] broken_link: Broken link: missing.md

Configuration

Parameter	Default	Description
`duplicate_threshold`	0.7	Similarity threshold for duplicates (0.0-1.0)
`ignore_patterns`	[]	Glob patterns to exclude from checks

Triggers

check duplicates / find duplicate docs
broken links / broken references
validate links / link check
censor

Integration

Loaded by Chronos as part of minimal, standard, and full presets.

Files

What ships with it

1 file 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.

Changes

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.

workflow

Use when a task is too large for turn-by-turn orchestration and should run through the big-task workflow lane: system-wide changes, large migrations, repo-wide audits, high-confidence verification, or tasks explicitly asking to run a workflow. Claude Code uses native dynamic workflows; Codex, OpenCode, and Grok use…
