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 | $0.00672 | $0.00672 |
| Opus 5 | $0.00336 | $0.00336 |
| Sonnet 5 | $0.00134 | $0.00134 |
| Haiku 4.5 | $0.00067 | $0.00067 |
Grade A, and why
Agent-Harness-Kit CLAUDE.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 4d 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
@AGENTS.md
Claude Code routing
On an uninitialized project's first response, including a greeting-only "oi"/"hello", begin visibly with the localized Kit-active welcome, then ask the delivery-mode preference (accompanied by default, autonomous, or hackathon) in the same cohesive kickoff question as any missing product intent. Asking correct discovery questions does not replace the welcome. Never repeat the welcome or mode question when context is approved or the choice is already explicit. See the first-run gate; read-only audits and eligible fast edits remain exempt.
Claude imports the shared map. Load relevant .claude/skills/, .claude/agents/, and the adapter.
Before mutating work or Harness ceremony, load .claude/skills/request-router/SKILL.md. Keep the four public lanes and separately assign assurance none|light|full. Full Harness is automatic only for two or more real agents, a human loop, required audit, insufficient model capability, unresolved consequential ambiguity, or explicit full; actual security/privacy/authorization/destructive changes require full audit, while API/dependency keywords alone do not. Read-only audits and diagnosis do not trigger first-run.
When graph expansion exposes an unresolved functionality or completion condition, ask through feature discovery before readiness; use scope_status: needs-discovery for existing unresolved nodes. Initial context approval never grants blanket authority over later scope.
For a new capability with open choices, automatically load .claude/skills/feature-discovery/SKILL.md; the user need not name it. Resolve failure/recovery before pending or graph changes.
Follow accompanied delivery: product builds pause at the first usable slice and material capabilities for actual client evaluation; affected work waits on product_requires, while unrelated authorized work may continue. Every new spec states explicit completion conditions, mirrored in acceptance_criteria with current observed verification evidence. Technical completion is not client approval. Small fixes remain continuous.
Use delivery modes: default accompanied, explicit autonomous end-to-end inside approved scope, or timeboxed hackathon with first-demo evaluation. Persist the choice in project context and preserve it on resume. No mode bypasses evidence or existing gates, restricts worker count by itself, or activates learning.
For planned work load writing-plans; target 15–30 active minutes per unit and justify exceptions. Full Harness may be compact or complete. Same-context inline nodes use an inline spec/transition; create handoff/review packets only for actual separate consumers. For full-Harness behavior/bugs load test-driven-task and climb the test ladder only as needed.
For assurance: light|full, use a fresh reviewer, REVIEW-ROUNDS.md, and SPEC authority—not prompt/conversation memory. none closes on executor verification.
Graph/full progress reads PENDING.md and TASK-GRAPH.md, follows STATUS-AND-COMPLETION.md, marks passing tasks completed, and keeps assurance non-blocking. Fast lanes return concise checked closeouts.
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.

Agent-Harness-Kit CLAUDE.md is an instructions file published in the GitHub repository Eduardo-Salvador/Agent-Harness-Kit (6 stars, last pushed yesterday), licensed MIT. It adds 672 tokens to every session, about $0.0034 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.
