Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

What it costs to keep this loaded
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 | $0.00066 | $0.01003 |
| Opus 5 | $0.00033 | $0.00502 |
| Sonnet 5 | $0.00013 | $0.00201 |
| Haiku 4.5 | $0.00007 | $0.00100 |
Grade A, and why
flutter-mcp-toolkit-dogfood-iterations 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 8d 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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Iteration workflow
Task Progress:
- [ ] Start app (web-showcase or make showcase)
- [ ] Fresh WS_URI from log (not stale after hot reload)
- [ ] Run battery
- [ ] Record score + warnings in tracker
- [ ] Promote recurring patterns if repeated ≥2 times
Web iteration
make web-showcase
export WS_URI="$(grep -Eo 'ws://127\.0\.0\.1:[0-9]+/[A-Za-z0-9_=-]+/ws' .showcase/web_app.log | tail -1)"
bash tool/evals/run_dogfood_eval.sh --ws-uri "$WS_URI" --merge --skip-visual # yq or dart fallback
# or without merge:
bash tool/evals/run_dogfood_eval.sh --ws-uri "$WS_URI"
Auto-runs: static gates + validate-runtime + webmcp verify.
Static only (CI / PR)
make dogfood-eval-static
Makefile
make dogfood-eval # needs WS_URI in env
make dogfood-eval-static

Exec vs MCP names
Document in iteration notes when testing invoke:
- exec: bare names (
get_recent_logs,dogfood_ping) — also acceptsfmt_*aliases - MCP:
fmt_prefix (fmt_get_recent_logs,fmt_client_tool+ listingname) - Connection: global

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.

flutter-mcp-toolkit-dogfood-iterations is a skill published in the GitHub repository Arenukvern/mcp_flutter (375 stars, last pushed 2d ago), licensed MIT. It adds 66 tokens to every session and 1,003 once invoked, about $0.0003 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 2026-09-03.
