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 | $0.00930 | $0.00930 |
| Opus 5.5 | $0.00372 | $0.00372 |
| Sonnet 5.5 | $0.00186 | $0.00186 |
| Haiku 4.5 | $0.00093 | $0.00093 |
Grade A, and why
agentic-sdk 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.
How it starts
The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Guidance for working on agentic-sdk itself. Read this before changing anything in this repo.
What this is
agentic-sdk is a runtime-agnostic skill system for software development across C, Zig, Clojure, and Elixir. This repo is the source. The authoritative design is docs/design.md; read it first when a change touches architecture, the install model, or the spine.
Layout
skills/<name>/SKILL.md: the atomic skill catalog (flat).skills/shared/holds the cross-cutting doctrine references, not a skill.agents/<name>.md: the 8-agent fleet.src/spine/+mino.edn: the deterministic spine (mino).test/spine/its tests.hooks/: hook templates (master form) plus the shared mino policy.templates/: the projectCLAUDE.mdandgitignoreskeletons.docs/design.md: the spec..opencode/agent/: derived, generated byagentic agents sync; never hand-edit.
This repo keeps its source at the root (skills/, agents/, mino.edn,
src/). The ~/.agentic-sdk/<project>/ home applies to installed projects, not here.
Non-negotiables
- Prose standard. No em-dashes, no ASCII arrows in prose, no process IDs,
terse humanized prose.
agentic lintenforces it; run it before every commit. - No leaks. Never name predecessor or private projects; the maintainer holds the forbidden-token list and it is never written into the public repo, not even as a ban list. No domain framing borrowed from another system. Generalize any product-specific example to the bounded stack plus Functional Core / Imperative Shell.
- Commits. jj-first. One line, category-first imperative subject
(
Skills: ...,Docs: ...,Fix: ...,Build: ...,Refactor: ...,Tests: ...). No body, no AI attribution, no version numbers. Never advance themainbookmark or push without the maintainer's say-so.
Before you commit
mino task test: the spine suite is green.agentic lint $(find docs skills templates hooks -name '*.md'): zero findings.agentic agents check .: the derived OpenCode agents match the masters.- Leak scan:
rg -ni '<forbidden tokens>' skills/ agents/ docs/ templates/ hooks/ src/
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.

agentic-sdk AGENTS.md is an instructions file published in the GitHub repository leifericf/agentic-sdk (5 stars, last pushed 1mo ago), licensed MIT. It adds 930 tokens to every session, about $0.0037 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.
