Error Analysis

Error Analysis is a skill for Claude Code, Codex from Raidriar7170/hermes-skilleval. It costs 13 tokens per session (59 once invoked), scanned A, original, MIT.

A skill for grouping failures and describing recurring error patterns in AI model or routing results.

In plain words
What is it for?
Use it to group top-choice misses and negative results, and to compare candidate systems with a baseline.
Why use it?
It makes repeated mistakes easier to understand than reviewing individual failures one by one.

Token cost

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.

Security

Grade A, and why

Error Analysis 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 6d 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

Error Analysis

Cluster failures and explain model or router error patterns.

Use Cases

  • Group top-1 misses and negative hits.
  • Summarize candidate-vs-baseline trade-offs.
Changes

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.
