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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 77 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00160 | $0.02064 |
| Opus 5 | $0.00080 | $0.01032 |
| Sonnet 5 | $0.00032 | $0.00413 |
| Haiku 4.5 | $0.00016 | $0.00206 |
Grade A, and why
alterlab-link-health scanned grade A with 1 finding 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 9d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
2. For HTTP URLs: `curl -sSI -L --max-time 15 '<new>'` — final status must be 200 (after redirects). How it starts
The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Link Health — Repo-wide Markdown Link Audit Methodology
A reusable methodology for bringing a broken docs-heavy repo's link checker to green. Codified from a real audit that took AlterLab-IEU/AlterLab-Academic-Skills from 1208 errors out of 1966 links to 0 errors out of 1912 links across 8 commits, with an auto-detected Tier 3 regression that validated the guardrail rule.
Quick Start
Full audit (fresh repo, failing link checker):
Audit and repair the link health of <owner/repo>. Run the full four-tier pipeline.
→ Dispatch the 10-agent audit from playbooks/full-audit.md, then the tiered APPLY phase.
Targeted residual pass (first dispatch reduced errors but some remain):
The link checker is down from 1208 to 67 errors. Close the residuals.
→ Dispatch the 3-agent followup pass from playbooks/followup-pass.md.
Post-merge cleanup (PR is green, need to finalize human-decision items):
Finalize the post-merge cleanup: resolve pending human-decision items, file follow-up issues, document link debt.
→ Dispatch the 4-agent post-merge pass from playbooks/post-merge.md.
Trigger Conditions
Trigger Keywords
English: link audit, dead links, link health, lychee, broken links, link checker, markdown link audit, link-health audit, 404 audit, check-links failing, CI link-check
繁體中文: 連結健檢, 死鏈, 失效連結, 斷鏈檢查, 連結審計
When This Skill Applies
- A weekly
Check Links(or similar lychee / markdown-link-check) workflow has been failing. - The user mentions a large error count (hundreds+) that they suspect is mostly config-driven false positives.
- The user wants to refactor broken intra-repo file references across many skills / docs.
- The user wants a reusable process for link debt maintenance going forward.
Non-Trigger Scenarios
| Scenario | Skill / Tool to Use Instead |
|---|---|
| Fix a single broken link in a single file | Direct Edit — no pipeline needed |
| Add a new URL to skill docs | alterlab-scientific-writing or the relevant domain skill |
| Verify a bibliography actually exists (DOI/author resolution, fabricated/hallucinated citations) | alterlab-citation-verifier — it cross-checks Crossref/OpenAlex/Semantic Scholar/arXiv. Link-health only repairs broken hyperlinks in docs; it never validates that a cited work exists. |
| Audit repo structure beyond links (schema, metadata) | Separate schema-drift audit (out of scope) |

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.

alterlab-link-health is a skill published in the GitHub repository AlterLab-IEU/AlterLab-Academic-Skills (66 stars, last pushed 8d ago), licensed MIT. It adds 160 tokens to every session and 2,064 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
