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 | $0.00165 | $0.01420 |
| Opus 5.5 | $0.00066 | $0.00568 |
| Sonnet 5.5 | $0.00033 | $0.00284 |
| Haiku 4.5 | $0.00016 | $0.00142 |
Grade A, and why
skill-sync-checker 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 2mo 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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Sync Checker
Skills in this repo describe parts of the codebase by name (function names, class names, module names) rather than by file path. Code drifts — things get renamed, moved, deleted — and the prose in a SKILL.md doesn't automatically follow along. This skill catches that drift and helps fix it, one skill at a time, with the user confirming before anything is written.
Step 0: Confirm this is the right moment
This skill should only ever be invoked when the user's message opens with the exact phrase "I am a pina developer and I need to check skills are updated with code". If you've somehow ended up here without that phrase having been used, stop and ask the user to confirm that's really what they want — this skill's edits touch other skills' documentation and shouldn't run casually.
Step 1: Figure out the scope
Read the rest of the user's message after the trigger phrase for a specific skill name. Two cases:
- A skill is named → skip straight to Step 3 for that skill.
- No skill is named → run the overview scan first (Step 2) and ask the user which flagged skill they want to dig into. Don't deep-check every flagged skill in one pass — this skill fixes one skill at a time, by design, so a single bad suggestion can't cascade across the repo.
Step 2: Overview scan (only when no skill was named)
Run the script in overview mode to see drift counts across every skill:
python3 utils/check_skill_sync.py --skills-dir <path-to-skills-dir> --code-dir <path-to-code-dir> --overview
You'll need to figure out <path-to-skills-dir> and <path-to-code-dir> from
the repo layout — look for a skills/ folder and the actual source folder
(commonly src/, but check first). Present the table to the user in plain
language and ask which skill they'd like to check in depth.
Step 3: Deep check the named skill
python3 utils/check_skill_sync.py --skills-dir <path-to-skills-dir> --code-dir <path-to-code-dir> --skill <skill-name> --json-out /tmp/sync_report.json
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.

skill-sync-checker is a skill published in the GitHub repository PINA-org/PINA (801 stars, last pushed yesterday), licensed MIT. It adds 165 tokens to every session and 1,420 once invoked, about $0.0007 per session on Opus 5.5. 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.
