aoa-decision is a skill for Codex from 8Dionysus/aoa-skills. It costs 62 tokens per session (1,022 once invoked), scanned A, original, Apache-2.0.

A workflow for finding, recording, correcting, or replacing lasting decisions in a software repository.

In plain words
What is it for?
Use it when you need to recover prior reasoning, update an accepted decision, or fix a mismatch between a decision record and its indexes.
Why use it?
It helps keep the original decision record authoritative when indexes, caches, or other derived files become outdated.

Skill for Codex

Written for Codex: agents/openai.yaml present.

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-decision 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 2d 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

Provide one front door for durable decision work without loading three procedures into every request. Keep owner-authored decision records authoritative; indexes, retrievers, KAG packets, caches, and session evidence may locate or contextualize a record but never supply its rationale.

Trigger boundary

Select this family only after the request fits its frontmatter description. Treat an undecided option, ordinary documentation edit, current authority map, or non-decision generated/runtime drift as a different task. Lack of evidence or write authority never becomes implicit approval.

Inputs

  • one decision intent and the target owner, subject, ID, path, or mismatch
  • exact owner routes, records, template, index contract, and effect authority for the exact effect, target, and scope required by the selected mode

Outputs

  • one typed result from references/contract.yaml with owner source, actual effects, verification, skipped checks, uncertainty, and stop line

Procedure

Choose exactly one mode:

Mode Select when Do not select when
find Existing rationale, status, supersession, or impact is requested. A write or correction is already known to be required.
record A meaningful accepted decision lacks an adequate owner record. The choice is open, trivial, already recorded, or only needs correction.
correct An existing decision record or its derived decision view is stale or wrong. The task is pure lookup, a current non-decision source-authority conflict, or a genuinely new decision.
  1. Read references/contract.yaml, then read the selected mode reference to EOF. Do not load another mode or a retired child bundle.
  2. Use an exact supplied owner root, decision ID, path, or source surface before discovery. Read the owner's route law before any source or generated write. If that law defines a disposable or non-VCS owner root, do not probe Git; use its named files, builder checks, and direct hashes or comparisons.
  3. Use a decision retriever only as an optional narrowing aid. Verify every rationale, status, supersession, and owner claim in the authored decision record.
  4. Execute one mode against one target. A handoff to another mode is a later selection, not an implicit continuation.
  5. Stop as blocked_missing_input before target reads or effects when a required owner source, accepted decision field, index contract, builder, or effect authority is unavailable. For a write, bind authorization to the exact effect, target, and scope. A current Operator or human authorization that already matches all three satisfies the approval gate without a repeated question; a new or changed effect, target, or scope requires fresh authorization.
  6. Return the selected mode, exact source refs, result state, actual effects, verification, skipped checks, residual uncertainty, and stop line.

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.
