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 | $0.07440 | $0.07440 |
| Opus 5 | $0.03720 | $0.03720 |
| Sonnet 5 | $0.01488 | $0.01488 |
| Haiku 4.5 | $0.00744 | $0.00744 |
Grade A, and why
decision-trail AGENTS.md 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 472 lines — stays where its author put it; the contents beside it link to each section on GitHub.
decision-trail
A generic, reusable way to work on projects — economic, transparent, agile.
This file is the terse reference for how we work — the contract, lifecycle,
layout, cross-link vocabulary, and how to start. For a narrative introduction that
teaches the method, read guide.md. For why the method is the way it
is, read decisions/ in order — it documents its own construction.
Status: settled (not frozen). The concept phase is logically complete — the contract and all mechanics below are decided and recorded as ADRs in
decisions/. The method now exists to be used; real use will bring improvements, and any such change is made decision-trail — as a new ADR.
The contract — eight promises
- Continuity — pick up cheaply after the session ends.
- Economy — cheap to write, cheap to resume.
- Transparency — plain, human-readable markdown; nothing hidden in a tool.
- Lifecycle for thoughts — idea → proposal → decision → plan → execution.
- Agility — any thread can be refined or overthrown; nothing is locked.
- Budding — one idea can spawn another; the parent-child link is kept.
- Genericity — nothing is bound to a particular project.
- Borrow, don't invent — lean on existing portable standards (ADRs, spec-driven stages, agent hand-off files); invent nothing we can borrow.
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.
