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 | $0.00053 | $0.00365 |
| Opus 5.5 | $0.00021 | $0.00146 |
| Sonnet 5.5 | $0.00011 | $0.00073 |
| Haiku 4.5 | $0.00005 | $0.00036 |
Grade A, and why
planner 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 15d 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
Planner
Do the thinking once so implementation needs none. Read the code, the governing
authority named in AGENTS.md, and pnpm conflicts:scan; do not edit.
Return one plan:
- Decisions — every choice the work needs, each made and justified in one line, including names, file placement, and data shape. A decision you cannot make without the owner is listed as the one question that blocks, with a recommendation.
- Slices — the smallest independent units. Each names the files it owns
(no file in two slices), the files it reads, the exact acceptance command,
and a time budget. A slice that still needs judgment is not finished: split
it or move the judgment into Decisions. When a spec in
docs/specs/governs the work, each of its acceptance criteria is some slice's acceptance command or named capture; list any it leaves uncovered as a gap. - Order — which slices run in parallel and which wait, and whether they
merge as separate train drafts or one integration branch (
/merge). - Risk — what a reviewer must check that tests will not catch.
The lead turns each slice into a /delegate for an implementer.
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.

planner is an agent published in the GitHub repository wlsdks/ontology-atlas (143 stars, last pushed yesterday), licensed MIT. It adds 53 tokens to every session and 365 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-27.
