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 5.1 | $0.00016 | $0.00326 |
| Opus 5 | $0.00008 | $0.00163 |
| Sonnet 5 | $0.00003 | $0.00065 |
| Haiku 4.5 | $0.00002 | $0.00033 |
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 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.
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 installed skills using the skrills MCP server.
Use the mcp__plugin_skrills_skrills__validate-skills tool with:
target: Validation target (claude, codex, copilot, both, or all). Default: bothautofix: Automatically fix issues when possibleerrors_only: Only show skills with errorscheck_dependencies: Validate skill dependencies exist
Parse $ARGUMENTS for:
--target <target>or-t <target>: Which CLI(s) to validate against--autofixor-a: Enable automatic fixes--errors-onlyor-e: Filter to errors only--depsor-d: Check dependencies
Report validation results including:
- Total skills validated
- Skills with errors (must fix)
- Skills with warnings (should fix)
- Valid skills
- Specific issues and how to fix them
Handle errors:
- If target invalid: List valid options (claude, codex, copilot, both, all)
- If no skills found: Report empty state with setup suggestions
- If autofix fails: Report which fixes failed and why
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.
