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.

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 | $0.00056 | $0.00499 |
| Opus 5.5 | $0.00022 | $0.00200 |
| Sonnet 5.5 | $0.00011 | $0.00100 |
| Haiku 4.5 | $0.00006 | $0.00050 |
Grade A, and why
flutter-dart-code-review 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.
What it actually says
/supergraph:flutter-dart-code-review
Library-agnostic Flutter/Dart code review. Graph-first, then checklist.
Announce: "🐦 /supergraph:flutter-dart-code-review — reviewing Flutter/Dart code..."
Steps
1. Graph analysis (surface hotspots before manual review)
Use CBM_PROJECT: call get_architecture with hotspots, then validated
hubs, cycles, complexity, cross-boundary, and test-gaps recipes. Apply
the existing Flutter thresholds: build() over 80–100 lines, complexity limits,
10+ dependents, circular DI, unexpected layer coupling, and untested files.
Serena (optional — if available):
mcp__serena__get_diagnostics_for_file(<file>) # type errors, null safety violations
mcp__serena__find_referencing_symbols(<symbol>) # callers of changed public APIs
mcp__serena__find_implementations(<interface>) # subclasses after interface change
Skip if Serena unavailable.
2. Manual checklist review
Work through CHECKLIST.md — 15 sections covering: General health · Dart pitfalls · Widgets · State management · Performance · Testing · Accessibility · Platform · Security · Dependencies · Navigation · Error handling · l10n · DI · Static analysis
Focus on areas flagged by step 1 first.
3. Report
## Flutter/Dart Review
- Graph hotspots: [list/none]
- Serena diagnostics: [issues/clean/skipped]
- Checklist: PASS | ISSUES (list critical items)
- Next: /supergraph:fix → /supergraph:verify
Rules
- Run graph analysis before opening checklist — prioritize hotspots
- Serena diagnostics catch null safety / type errors manual review misses
- State management rules apply to ALL solutions (BLoC, Riverpod, GetX, MobX, Signals)
- Full checklist in CHECKLIST.md
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-dart-code-review is a skill published in the GitHub repository datit309/supergraph (22 stars, last pushed 2d ago), licensed MIT. It adds 56 tokens to every session and 499 once invoked, about $0.0002 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.
