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.

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 | $0.00010 | $0.00243 |
| Opus 5 | $0.00005 | $0.00121 |
| Sonnet 5 | $0.00002 | $0.00049 |
| Haiku 4.5 | $0.00001 | $0.00024 |
Grade A, and why
validate-skills 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 today.
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
Validate Skills
Validate one Markdown file, every Markdown file below one directory, or the
default plugin command and skill paths. The optional --json flag may appear
before or after the path.
Execution
Resolve ${CLAUDE_PLUGIN_ROOT}/scripts/validate-skills.py and execute it with
the invocation arguments passed as distinct values. Do not evaluate or
re-tokenize user input. Preserve the helper's exit status.
In --json mode, return helper stdout unchanged and do not add a completion
marker or explanatory text. Otherwise return the rendered validation report.
Supporting Rules
The packaged helper implements these shared contracts. Read them completely when interpreting a finding or changing validation behavior:
${CLAUDE_PLUGIN_ROOT}/lib/validate-skills/classification.md${CLAUDE_PLUGIN_ROOT}/lib/validate-skills/execution.md${CLAUDE_PLUGIN_ROOT}/lib/validate-skills/ai-review.md
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.

validate-skills is a command published in the GitHub repository gopherguides/gopher-ai (21 stars, last pushed today), licensed MIT. It adds 10 tokens to every session and 243 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
