agentic-evals

agentic-evals is a skill for Claude Code, Codex from grahama1970/agent-skills. It costs 60 tokens per session (5,546 once invoked), scanned A, original, no licence file.

A workflow for evaluating coding-agent skills through repeated test trials. It checks command results, the agent's sequence of actions, safety rules, and the evidence supporting a readiness score.

In plain words
What is it for?
Use it to run multi-trial skill evaluations, validate agent trajectories, check deterministic commands and safety constraints, and score workflow readiness.
Why use it?
It helps reveal whether a skill works reliably across different attempts instead of relying on a single successful example. The checks also expose unsafe or incomplete agent behavior.

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

agentic-evals scanned grade A with 1 finding 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.

The scan reads SKILL.md. This mod also ships 19 executable files (fixtures/selftest/prod.sh, run.sh, sanity.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

`evidence_class` is not inferred from a command containing `run.sh` or `curl`.

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.
