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 | $0.00372 | $0.00372 |
| Opus 5.5 | $0.00149 | $0.00149 |
| Sonnet 5.5 | $0.00074 | $0.00074 |
| Haiku 4.5 | $0.00037 | $0.00037 |
Grade A, and why
agent-playbook 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 2mo 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
Agent Playbook Maintainer
Session Bootstrap
- Read
.agents/agulater.jsonfor the top-level Agent Operational Contract. - Read
.agents/AGENTS.mdfor the portable operating contract. - Read
.agents/harness.jsonfor context, loop, tool, and checkpoint policy. - Read
.agents/context/core.mdbefore orienting to a new task. - Read
.agents/context/task-brief.mdand update the working set only for the active task. - Load a matching skill from
.agents/skills/only when its description fits the task.
Context Discipline
- Keep this root file short; it is a bootstrap route, not a full project dump.
- Treat the active working set and handoff as compact state, not hidden memory.
- When context pressure or a phase boundary occurs, preserve goal, evidence,
decisions, verification, risk, and the next action in
.agents/context/handoff.md.
Runtime Boundary
This configuration describes intended behavior. It does not grant tools, permissions, network access, file mutation, or background execution. The host runtime remains authoritative for those capabilities.
Project Rules
- Treat
.agents/agulater.jsonas this repository's dogfooded Agent Operational Contract. - Keep Agulater's owned model central: context, harness, loop, graph, capabilities, and evidence. External systems are references, not semantic authorities.
- When changing generated contract structure, update the generator, the root dogfood kit, the research example, tests, and audit together.
- Use Bun + TypeScript for authoring tools. Keep them local-only and do not add execution authority, model calls, or hidden memory.
- Validate with
bun run testbefore handing off a change.
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.
