Conciseness

Lean and dense with operational specifics throughout — the port-8550 rationale is delivered in four lines with a code excerpt, and no section explains concepts Claude already knows (there is no 'what is Flet' or 'how Flutter works' padding). Matches anchor 5: every token earns its place.

Actionability

Fully executable, copy-paste-ready commands cover the common cases: 'uv run flet run -w -p 8550 examples/...', 'fvm flutter run -d macos', '-d chrome', '-d web-server --web-hostname 127.0.0.1 --web-port 8660', plus concrete hot-reload keys (r, R, q). Only trivial gap: 'open -a' is macOS-specific. Matches anchor 5.

Workflow Clarity

Clear multi-step sequence (start the Python app on 8550, run the local Flutter client on the right target, interact, read evidence from both sides, hot reload/restart, finish checklist) with explicit validation checkpoints in 'Reading evidence' and 'Finish checklist' and an error-recovery feedback section in 'Troubleshooting' (escalation fallback, web-server fallback). This is not a destructive or batch operation, so the validation cap does not apply. Matches anchor 5.

Progressive Disclosure

Well-organized sections with clear headers and appropriate placement of nearly all content, but everything is inline — there are no bundle or reference files at all, and ~150 lines of troubleshooting/browser-interaction detail could partly live in one-level-deep reference files. Matches anchor 4 (good structure, minor organization gaps); not anchor 5, which requires well-signaled references.

Specificity

Names several concrete elements — 'testing or debugging Flet apps', 'local Python package sources', 'local Flutter client', 'web, desktop, browser, and computer-use verification workflows' — though 'verification workflows' is somewhat abstract and no specific operations or commands are named. It exceeds anchor 3 (which expects only 1-2 concrete actions) but falls short of anchor 5's comprehensive action list.

Completeness

An explicit 'Use when ...' trigger clause with concrete conditions (maintainer/contributor dev mode, local packages, local Flutter client) is present, and the what (testing/debugging/verification of Flet apps) is stated, but the what is conflated into the single when-clause rather than given as a distinct capability statement. This sits between anchor 4 and anchor 5; it is not the exemplary two-part what+when structure of anchor 5.

Trigger Term Quality

Good natural keyword coverage — 'testing', 'debugging', 'Flet', 'development mode', 'web', 'desktop', 'browser', 'computer-use' — matching phrases a maintainer would naturally say. A few common variations are missing ('run locally', 'smoke test', 'Flutter client'), keeping it below anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

Clear niche with distinct triggers — 'Flet', 'maintainer/contributor development mode', 'local Flutter client' — that would not naturally collide with generic testing or app-development skills. Matches anchor 5 (clear niche, minimal conflict risk).
