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 | $0.00155 |
| Opus 5.5 | $0.00006 | $0.00062 |
| Sonnet 5.5 | $0.00003 | $0.00031 |
| Haiku 4.5 | $0.00002 | $0.00015 |
Grade A, and why
explain-error 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.
What it actually says
explain-error
Use this when the user pastes an error, a stack trace, or failing build output.
- Find the actual failure: the first real error, not the cascade of messages after it.
- Explain in plain language what it means and the most likely cause.
- Point at the specific file and line when the trace gives one.
- Suggest one or two concrete fixes, with the exact change to make.
- If the cause is ambiguous, say what to check or run next to narrow it down.
Prefer the smallest fix that addresses the root cause over a workaround, and say so when you are guessing rather than certain.
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.

explain-error is a skill published in the GitHub repository Brattlof/skillet (9 stars, last pushed yesterday), licensed MIT. It adds 16 tokens to every session and 155 once invoked, about $0.0001 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 2026-08-31.
