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 | $0.01007 | $0.01007 |
| Opus 5.5 | $0.00403 | $0.00403 |
| Sonnet 5.5 | $0.00201 | $0.00201 |
| Haiku 4.5 | $0.00101 | $0.00101 |
Grade A, and why
nanostack 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 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.
How it starts
The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Nanostack: Agent Discovery
This file lists every built-in skill shipped by Nanostack for the verified adapters: Claude Code, Cursor, OpenAI Codex, OpenCode, and Gemini CLI. Each skill folder contains a SKILL.md for adapter discovery and an agents/openai.yaml for OpenAI-compatible agents. Adapter capability evidence lives in adapters/<host>.json; treat the JSON as the single source of truth for what a given host actually enforces (hook execution, write guard, phase gate).
Available skills
Default sprint
/feature coordinates the built-in sprint, either directly or after /think --autopilot completes its brief. /nano returns a plan; review, security, and QA return findings. Repairs happen in build after verification readers stop, then verification runs again. Automatic plan approval does not authorize publication.
| Skill | Directory | Description |
|---|---|---|
| think | think/ |
Refines a rough idea before code: questions one at a time, alternatives with trade-offs, design walked in sections. Calibrated per archetype. Saves a structured artifact (value proposition, scope mode, target user, narrowest wedge, key risk, premise validation). |
| nano | plan/ |
Implementation planning. Planned files, plan approval, scope assessment, product standards. |
| review | review/ |
Two-pass code review (structural + adversarial). Scope drift detection against /nano. Conflict precedence with /security. |
| qa | qa/ |
Browser, API, CLI, or debug testing. Reports reproducible findings without repairing product code. |
| security | security/ |
OWASP Top 10 + STRIDE audit. Cross-references /review for conflicts. |
| ship | ship/ |
Pre-flight, PR creation, CI monitoring, post-deploy verification. Generates the sprint journal on success. |
| compound | compound/ |
Knowledge capture after /ship. Promotes proven solutions across sprints (bug, pattern, decision) with confidence and applied_count. |
Orchestration and safety
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.

nanostack AGENTS.md is an instructions file published in the GitHub repository garagon/nanostack (207 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 1,007 tokens to every session, about $0.0040 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 2026-08-30.
