Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.03872 | $0.03872 |
| Opus 5 | $0.01936 | $0.01936 |
| Sonnet 5 | $0.00774 | $0.00774 |
| Haiku 4.5 | $0.00387 | $0.00387 |
Grade B, and why
flutter-agentic AGENTS.md scanned grade B with 1 finding 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 3d 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.

Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.
**Skills live in two parallel trees — keep them in sync.** Both Claude Code (`.claude/skills/`) and Codex CLI (`.codex/skills/`) read per-skill `SKILL.md` folders, but in different formats: Claude skills are thin (body + This is a copy
94% identical to flutter-agentic copilot-instructions.md — 58 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

$release) — when asked to do a release, follow these steps interactively; ask for confirmation at each step before proceeding:- Load
GH_TOKENfrom the git-ignored root.env(set -a && . ./.env && set +a) — release auth is explicit because the repo uses multiple GitHub accounts — then checkgh auth statusreports(GH_TOKEN). Source.envin every shell that runsgh. If.envlacks a token, create a fine-grained PAT (Contents: Read and write) at https://github.com/settings/personal-access-tokens/new and addGH_TOKEN=…. Stop if not ready. Ifgh auth statusreports the token as invalid, confirm the shell has network access before replacing it — in a sandboxed agent environment, blocked network access can surface as an auth failure; re-run with network permission and.envsourced first. - Get current branch (
git branch --show-current). Confirm release branch with user. - Compare to main:
git log main..{BRANCH} --oneline+git diff main..{BRANCH} --stat. Show commits. - Read version (
grep "^version:" pubspec.yaml). Propose bump: Major = breaking; Minor = feat: or new component/skill; Patch = fix/chore/docs. Wait for confirmation. - Edit
pubspec.yamlwith confirmed version. - Create
docs/releases/v{VERSION}.mdfromdocs/releases/_template.md. Two sections: Features (what developers gain) and Agent Context Improvements (what agents gain). Plain language, one sentence per bullet, no duplicates. Show draft and wait for confirmation. - Commit:
git add pubspec.yaml docs/releases/v{VERSION}.md && git commit -m "chore: release v{VERSION}" && git push - Merge:
git checkout main && git pull origin main && git merge --no-ff {BRANCH} -m "chore: merge {BRANCH} into main for v{VERSION}" && git push origin main - Tag and release:
git tag v{VERSION} && git push origin v{VERSION}thengh release create v{VERSION} --title "v{VERSION} — {TITLE}" --notes-file docs/releases/v{VERSION}.md --target main. Report URL. - Ask to delete release branch. If yes:
git branch -d {BRANCH} && git push origin --delete {BRANCH}

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.
