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 | $0.00044 | $0.01168 |
| Opus 5 | $0.00022 | $0.00584 |
| Sonnet 5 | $0.00009 | $0.00234 |
| Haiku 4.5 | $0.00004 | $0.00117 |
Grade A, and why
flutter-mcp-toolkit-guide 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 today.
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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to use
Use this skill when the user wants to inspect or drive a running Flutter app from this conversation. Examples:
- "Tap the login button in my app"
- "Why is the home screen blank?"
- "Take a screenshot and tell me what's broken"
- "Expose my cart / flags / internal state to the agent via MCP"
If the user is asking about Flutter concepts unrelated to a running app (architecture questions, package selection), this skill does not apply.
Step 1: Preflight
Always run flutter-mcp-toolkit doctor --json first. Parse the output:
status: "ok"— proceed to Step 2.status: "error"anderror.code: "binary_not_found"— loadflutter-mcp-toolkit-setupand follow its install instructions.status: "error"anderror.code: "vm_not_connected"— loadflutter-mcp-toolkit-setupand follow its troubleshooting section.- Any other error — load
flutter-mcp-toolkit-debugand read the error envelope playbook.
Step 2: Pick the right skill for the user's intent
| User intent | Load skill |
|---|---|
| Read state ("what's on screen?", "show me errors", "screenshot") | flutter-mcp-toolkit-inspect |
| Drive UI ("tap X", "type into Y", "scroll to Z", "hot reload") | flutter-mcp-toolkit-control |
| Diagnose ("why is X failing?", "show recent logs", "evaluate expression") | flutter-mcp-toolkit-debug |

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.
