link-check

link-check is a skill for Claude Code, Codex from jmagly/aiwg. It costs 29 tokens per session (1,819 once invoked), scanned A, original, MIT.

A checker for @file references in AIWG skills and agents. These references point one file or piece of project content to another.

In plain words
What is it for?
It helps scan one file, a directory, or the full AIWG code collection, produce a report, and optionally update older reference formats.
Why use it?
It finds broken or outdated references before they cause documentation, deployment, or automation problems.

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

link-check 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.

How it starts

The opening of the file, as written. The whole thing — 176 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You verify every @file reference in AIWG distributable skills and agents against the full linking contract, producing a structured PASS/WARN/FAIL report per reference. You can run against a single file, a directory, or the full agentic/code/ corpus, and optionally auto-migrate legacy bare refs to the @$AIWG_ROOT/ prefix.

Triggers

  • "link check" / "check links" → run against current file or directory
  • "link check agentic/code/" → full corpus scan
  • "link check --fix" → auto-migrate legacy bare refs
  • "any bad links?" → run link-check on current context
  • "check for broken @-refs" → run link-check
  • "are there any legacy bare refs?" → run link-check, focus on 4b

Usage

/link-check [path] [options]
Argument Default Description
path current file or agentic/code/ File or directory to check
--fix off Auto-migrate @agentic/code/, @src/, @docs/, @tools/@$AIWG_ROOT/
--report off Output structured JSON report instead of human-readable
--aiwg-only off Check only .aiwg/ refs (skip bare-core and forbidden checks)
--fail-on-warn off Treat WARN as FAIL (useful for CI)

Reference Classification

Each @<path> reference is classified per the AIWG linking contract:

Pattern Result Reason
@$AIWG_ROOT/<path> PASS AIWG core file, install-relative
@$TOKEN/<path> — TOKEN set in env PASS Registered corpus token
@$TOKEN/<path> — TOKEN NOT set WARN Unknown token — add to .env or export
@.aiwg/<path> — in Tier 1/2 allowlist PASS Normalized project memory
@.aiwg/<path> — not in allowlist FAIL Repo-local only — silently fails in user projects
@.claude/<path> FAIL Deployment target — forbidden in distributable source
@agentic/code/<path> WARN Legacy bare ref — use @$AIWG_ROOT/agentic/code/
@src/<path> WARN Legacy bare ref — use @$AIWG_ROOT/src/
@docs/<path> WARN Legacy bare ref — use @$AIWG_ROOT/docs/
@tools/<path> WARN Legacy bare ref — use @$AIWG_ROOT/tools/
Relative path within component PASS Local ref

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.
