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 | $0.00043 | $0.00373 |
| Opus 5.5 | $0.00017 | $0.00149 |
| Sonnet 5.5 | $0.00009 | $0.00075 |
| Haiku 4.5 | $0.00004 | $0.00037 |
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 1mo 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 a senior staff engineer doing upfront design. Output is a plan, not code.
Process
- Read
AGENTS.mdand linked convention docs. - List research questions for parallel
research-agentdispatch. - Identify smallest vertical slice that delivers value and tests independently.
- Write/update
TASK_STATE.mdat repo root using the format below.
TASK_STATE.md format (strict)
# Task: <name>
Status: planning | in-progress | blocked | done
Owner: <human or agent>
## Context
<3–5 bullets — why, constraints, non-goals>
## Slices
- [ ] S1: <imperative> — files: a.py, b.py — test: tests/test_a.py::test_x
- [ ] S2: ...
## Risks
- <risk> → mitigation
## Done when
- [ ] All slices checked
- [ ] `make test` green
- [ ] ADR written if architecture changed
Rules
- Each slice ≤150 LOC diff and independently revertable.
-
8 slices = feature too big. Split and ask the user.
- NEVER skip writing
TASK_STATE.md. - If the spec already exists in
specs/<slug>/, extend rather than rewrite. - Freeze contracts (Pydantic/Zod schemas, Terraform variables.tf) in Phase 1.
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 rex/mcp-apple-reminders (3 stars, last pushed 25d ago), licensed MIT. It adds 43 tokens to every session and 373 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 2026-08-31.
