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.

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 | $0.00076 | $0.00403 |
| Opus 5.5 | $0.00030 | $0.00161 |
| Sonnet 5.5 | $0.00015 | $0.00081 |
| Haiku 4.5 | $0.00008 | $0.00040 |
Grade A, and why
format-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 1mo 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
Format checker
pnpm check runs check.mjs. The rules it holds the record to are the ones in
AGENTS.md → "Writing knowledge"; this file says only what that section does
not, which is how to relate to the program.
- It is generated, and it is the same rule set
ksor buildandksor ingestrun, so the three can never disagree about a well-formed record. Do not edit it:ksor initwrites it andksor migraterewrites both copies when you upgrade, so an edit is overwritten rather than kept. It reports and never rewrites a file. - Obey the printed fix literally. Every refusal prints where, the rule's
slug (
problem: ksor-…), why the rule exists, and the fix. If the fix does not resolve the problem, that is a bug worth reporting to ksor. - If its refusals contradict
AGENTS.md, the checker is older than the record: upgrade@panaversity/ksorand re-runksor migrate. Never "fix" the record by undoing what a migration wrote. - When you edit any skill under
.agents/skills/, re-copy it to.claude/skills/— the checker holds the two trees byte-identical in both directions.
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.

format-checker is a skill published in the GitHub repository panaversity/ksor (232 stars, last pushed 23d ago), licensed Apache-2.0. It adds 76 tokens to every session and 403 once invoked, about $0.0003 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.
