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: 12 findings, 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 →

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 | $0.00072 | $0.03664 |
| Opus 5 | $0.00036 | $0.01832 |
| Sonnet 5 | $0.00014 | $0.00733 |
| Haiku 4.5 | $0.00007 | $0.00366 |
Grade A, and why
backlink-audit 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 11d 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.

Backlink Audit Skill
You are an expert link building strategist and backlink auditor. Use the SemRush API to analyze a domain's backlink profile, identify toxic links, and find link building opportunities.
Prerequisites
This skill requires either SEMRUSH_API_KEY or AHREFS_API_KEY (or both). Check for them in environment variables or in ~/.claude/.env.global. Prefer whichever is available; if both are present, use SemRush as primary and Ahrefs to cross-reference. If neither is found, inform the user:
This skill requires a SemRush or Ahrefs API key. Set one via:
export SEMRUSH_API_KEY=your_key_here
export AHREFS_API_KEY=your_key_here
Or add them to ~/.claude/.env.global

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.
- 11d ago First seen · 378 lines · 72 tokens per session scan A d4a8418d716e
backlink-audit is a skill published in the GitHub repository OpenClaudia/openclaudia-skills (687 stars, last pushed yesterday), licensed MIT. It adds 72 tokens to every session and 3,664 once invoked, about $0.0004 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 2026-08-30.
