repo-links

repo-links is a skill for Claude Code, Codex from rjwalters/kicad-tools. It costs 21 tokens per session (6,133 once invoked), scanned A, original, MIT.

An internal-link checker that verifies Markdown links, documentation paths, and connections between repository skills resolve to files that exist.

In plain words
What is it for?
Use it to check a whole repository or selected files and fix clear broken references.
Why use it?
Renaming or deleting files can leave broken references that are easy to miss. Finding them keeps repository documentation and skill files connected to the files they mention.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is "notes": "../notes",.

Good fit Use it to check a whole repository or selected files and fix clear broken references.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

repo-links 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 2d 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 — 510 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Codex form of the /repo:links command. Other commands appear as $repo-<verb> skills. Helper scripts and .claude/ paths below are relative to the repository root and exist when the Claude Code surface is installed alongside this one.

Validate that internal cross-references across the repo actually resolve. Catches broken links from reorganization, renames, and deletions.

This is the cross-reference layer of [[docs]]. Use it directly when that's all you want to check; use [[docs]] for the full documentation sweep.

Usage

$repo-links                    # Full repo — fix unambiguous links, report as you go
$repo-links CLAUDE.md          # Check one file
$repo-links .claude/           # Check skill/command files
$repo-links --ask              # Review findings and confirm before fixing

What It Checks

1. Markdown Links

Scan all .md files for [text](path) links where path is a relative file path (not a URL). Verify the target exists on disk.

Strip code before scanning. Remove fenced blocks and inline code spans from the text first — a [text](path) inside backticks is a description of a link, not a link:

text = re.sub(r'```.*?```', '', text, flags=re.S)   # fenced blocks
text = re.sub(r'`[^`]*`', '', text)                  # inline spans

Without this the checker flags the sentences in this very file, and in [[audit]], that explain what it looks for. A checker that reports its own documentation as broken is not a checker anyone keeps running.

Skip:

  • External URLs (http://, https://)
  • Anchor-only links (#section)
  • Image URLs from external services

Resolve against two bases, and only report a link that fails both. A relative path can legitimately be written against either the file's own directory or the repo root, and both conventions are in active use:

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.
