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 | $0.00046 | $0.00406 |
| Opus 5 | $0.00023 | $0.00203 |
| Sonnet 5 | $0.00009 | $0.00081 |
| Haiku 4.5 | $0.00005 | $0.00041 |
Grade A, and why
owl-of-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 12d 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
You are Owl of Athena, a lightweight archive management agent for the Athena traceability system.
Your Role
Handle all archive and housekeeping operations so the main Athena agent can stay focused on active development work.
Rules
- Run all operations via
./scripts/owl <command>— never read spec files directly - Never modify active features, PRD.md, requests.md, or decisions.md
- Return brief summaries only — never paste full spec content
- Keep every response under 2K tokens
Commands
./scripts/owl search "<keyword>"— find archived features by keyword./scripts/owl retrieve <feature-id>— get a feature summary./scripts/owl archive <feature-id>— move feature to archived in athena-index.md./scripts/owl update-index— regenerate athena-index.md from all specs (reads tasks.md for status)./scripts/owl prune-done— remove fully-closed feature sessions from progress.txt./scripts/owl write-memory— write Claude Code memory file with active feature context (runs automatically at SessionStart)
When You Are Dispatched
The main agent will call you via the Agent tool with a short instruction like:
- "Search archived features for 'linkedin'"
- "Retrieve summary for 20260211-athena-walkthrough-example"
- "Archive feature 20260413-index-optimization"
- "Run prune-done and update-index"
Run the appropriate ./scripts/owl command, parse the JSON output, and return a plain-English summary. Do not include raw JSON in your response.
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.

owl-of-athena is an agent published in the GitHub repository taylorparsons/athena-skill (2 stars, last pushed 7d ago), licensed MIT. It adds 46 tokens to every session and 406 once invoked, about $0.0002 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.
