A process for delivering software changes from a product requirements document, with an audit trail covering requests, decisions, specifications, tasks, and commits. It uses a project script called owl to control access to certain records.

Managing feature, bug-fix, and other repository changes through documented requirements, decisions, specifications, tasks, notes, and commits.

It keeps feature and bug work traceable and requires the original request to be recorded before changing requirements or code. It also defines which project documents may be read or edited directly.

athena — Skill for Codex by taylorparsons

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.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00055	$0.01350
Opus 5	$0.00028	$0.00675
Sonnet 5	$0.00011	$0.00270
Haiku 4.5	$0.00006	$0.00135

Security

Grade A, and why

athena 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 9d ago.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/bootstrap_git_audit.py, scripts/commit_with_traceability.py, scripts/owl.py, …), 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.

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.

How it starts

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ATHENA Loop

The audit trail lives in docs/ but is script-gated: never Read docs/requests.md, docs/decisions.md, docs/athena-index.md, or archived specs — all access goes through ./scripts/owl (deterministic, zero-token). You may Read/Edit directly only:

the active feature's docs/specs/<FEATURE_ID>/spec.md, tasks.md, notes.md
the docs/PRD.md sections you are changing — never the full file: locate the section with grep, read only that line range; one requirement → owl show <FR-ID>
docs/TRACEABILITY.md

1) Open the session

Claude Code: if the Athena Active Context memory is present, use it and skip the next step.
Otherwise run ./scripts/owl context — prints active feature, goal, IN PROGRESS/NEXT, recent CR/D IDs, and the latest request.
Repo has no docs/ audit files, or still has docs/progress.txt? See references/setup.md.
Summarize the session goal in one sentence before changing anything.

2) Capture input first

No PRD or code changes until the session's customer request is captured verbatim (redact secrets):

./scripts/owl add-request <<'EOF'
<verbatim customer request>
EOF

Returns the CR-... ID. No explicit request this session? Ask the user for one.

Whenever you interpret ambiguity, choose tradeoffs, or change scope:

./scripts/owl add-decision --cr <CR-ID> --prd "<PRD section>" <<'EOF'
Decision: <what>
Rationale: <why>
Alternatives considered: <rejected options and why>
EOF

3) Reflect in PRD and spec

If the newest CR is not reflected in docs/PRD.md, update the PRD first. Tag every added or changed requirement (Sources: CR-...; D-...) — at least one CR, plus a D whenever interpretation was needed.
Establish a FEATURE_ID (YYYYMMDD-short-name; ask if unclear). Ensure docs/specs/<FEATURE_ID>/spec.md and tasks.md exist (copy from templates/).
Traceability is mandatory: FRs have stable IDs and Sources:; acceptance scenarios have Verifies: FR-...; tasks have Implements: FR-.... Fix broken links before writing code.

What ships with it

20 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.
