aoa-eval

aoa-eval is a skill for Codex from 8Dionysus/aoa-skills. It costs 68 tokens per session (1,182 once invoked), scanned A, original, Apache-2.0.

A routing workflow for choosing or applying an evaluation, meaning a planned check of whether a system meets a specific expectation.

In plain words
What is it for?
Use it to select an existing evaluation, design a bounded suite when none fits, or classify supplied session findings as evaluation candidates.
Why use it?
It keeps evaluations tied to the right owner and evidence, instead of treating ordinary tests or vague requirements as formal evaluation results.

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

aoa-eval 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 11d 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.

Intent

Route one evaluation need to the narrowest procedure that preserves its real owner, input contract, output, and proof limit. Consolidation here is a shared front door, not a collapse of five different capabilities into generic prose.

Trigger boundary

Use this skill when:

  • an eval surface must be selected or applied
  • an established no-fit needs a local intake packet or a bounded suite design
  • researched eval-trigger classes and supplied or retrieved session hits need eval-owned candidate classification

Do not use this skill when:

  • the task is an ordinary test run, the invariant is still unknown, the real need is generic session harvesting, or the requested effect is central proof promotion

Inputs

  • one mode intent plus its owner, source ref, acceptance target, relevant evidence or inventory, effect authority, and required environment details

Outputs

  • one mode-specific result defined by references/contract.yaml, including owner, evidence class, proof limit, next route, and stop line

Procedure

Record <bundle_dir> as the directory containing this loaded SKILL.md.

Choose exactly one mode

Mode Use when Required procedure
select No exact evidence surface has been selected. references/select.md
apply The exact surface and acceptance contract are explicit. references/apply.md
local-need Selection proved no fit and an existing local eval port should receive pressure. references/local-need.md
design Selection proved no fit and a stable invariant needs a bounded local suite or report design. references/design.md
session-mining Prior research defined eval-trigger classes that need real session examples. references/session-mining.md

Mode: select

Mode: apply

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

aoa-eval is a skill published in the GitHub repository 8Dionysus/aoa-skills (4 stars, last pushed 2d ago), licensed Apache-2.0. It adds 68 tokens to every session and 1,182 once invoked, about $0.0003 per session on Opus 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.
