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 | $0.09184 | $0.09184 |
| Opus 5.5 | $0.03674 | $0.03674 |
| Sonnet 5.5 | $0.01837 | $0.01837 |
| Haiku 4.5 | $0.00918 | $0.00918 |
Grade A, and why
idd-skill 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 2d 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 — 672 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Guidelines for AI Agents
This repository distributes the IDD (Issue-Driven Development)
workflow — a portable set of .github/instructions/ files that
wire up a multi-agent issue-driven pipeline for any GitHub
project.
This file is the canonical, tool-neutral instruction source for AI
coding agents in this repository, following the
AGENTS.md open standard that Codex CLI, OpenCode,
Grok Build, Cursor CLI, and GitHub Copilot (CLI, coding agent, and Chat)
all discover automatically at the repository root. CLAUDE.md and
GEMINI.md are thin adapters that import this file for Claude Code and
Antigravity CLI (formerly Gemini CLI), the two tools in this
repository's harness mix that read their own dedicated entry file
instead, and
.github/copilot-instructions.md
carries only the small amount of guidance specific to GitHub Copilot's
own UI terminology. See docs/ai-strategy.md for
the reasoning behind this layout.
Minimum requirements
- Match the conversational language to the user's language.
- Write comments and documentation in English unless there is a clear project-specific reason otherwise.
- When editing
README.md, also apply the equivalent change toREADME.ja.md, and vice versa. Keep both files in sync in the same commit. - Avoid hard-coded repository file counts in docs unless the number is mechanically maintained. If count-based wording is necessary, update every mirrored reference in the same commit.
- When documentation or instruction text names an anti-pattern or failure mode, cite the observed incident per docs/idd-design-rationale.md.
- Continue autonomously for low-risk work, but pause and ask a concise question when uncertainty or hidden risk makes the next step unsafe. When that pause is needed, provide one or more recommended response options.
- Keep changes small and reviewable. Follow the project's Conventional Commits rules and keep each commit atomic.
- Do not modify community documents (
CODE_OF_CONDUCT*,CONTRIBUTING*) without explicit approval.
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.

idd-skill AGENTS.md is an instructions file published in the GitHub repository kurone-kito/idd-skill (11 stars, last pushed today), licensed MIT. It adds 9,184 tokens to every session, about $0.0367 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.
