stream-flutter

Build and integrate Stream Chat, Video, and Feeds in Flutter apps. Use for Flutter/Dart project work with Stream package setup, auth wiring, and widget blueprints. Supports stream_chat_flutter (pre-built Chat UI), stream_chat_flutter_core (custom Chat UI), stream_video_flutter (Video calling and livestreaming), and stream_feed / stream_feed_flutter_core (Activity Feeds, no pre-built UI). Also migrates Flutter apps from the Sendbird Chat SDK (sendbird_chat_sdk / sendbird_uikit) to Stream Chat.

Content

70%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

Highly actionable and well-sequenced routing content undermined by significant redundancy and a bundle/structure mismatch: six of the top-level modules the router depends on are absent from the bundle, while their would-be content is inlined into SKILL.md instead. The result is a router that is simultaneously too long and incomplete as shipped.

Suggestions

State each cross-cutting rule once (design-matching read procedure, permissions prerequisite) in its owning section or RULES.md and reference it by name elsewhere, cutting the near-verbatim repeats from the styling-depth flag, 'After classification', Module map, A4/B4, and Step 0.5 sections.

Ship the referenced module files (RULES.md, builder.md, sdk.md, design-matching.md, custom-ui.md, sendbird-migration.md) in the bundle, or fold their content into the files that do exist so no link in SKILL.md dangles.

Move the Step 0.5 credentials/seed-data procedure (CLI command bodies, channel seeding sub-steps C1–C4) into builder.md or a references/ file, leaving SKILL.md with just the upfront question and a pointer — that alone would roughly halve the router.

DimensionReasoningScore

Conciseness

Noticeably verbose for a router file: the design-matching procedure-half instruction ("read its procedure half in full — everything above the # Reference divider... may span two Reads... then Grep its Reference half per region") is repeated near-verbatim in the styling-depth flag, 'After classification', and the Module map, and the permissions prerequisite is restated four times (Step 0.5, A4, B4, Step 0 cross-reference). It assumes Claude's competence (no basic-concept padding), but roughly a third of the ~410 lines is redundant restatement or over-emphatic hammering that a single canonical statement per rule would cover — below the 'mostly efficient' level 3.

2 / 5

Actionability

Fully executable: exact CLI commands (getstream env/token/api with complete JSON request bodies), a copy-paste bash project-signals probe, verbatim user-facing questions, and precise SDK symbols (StreamTheme vs StreamChatThemeData, StreamComponentBuilders slot names). Placeholders like <token_user_id> are the appropriate parameterization, not pseudocode.

5 / 5

Workflow Clarity

Clear sequenced phases (A1–A4, B1–B4, M1–M5, Steps 0/0.5) with explicit validation and error-recovery loops: 401 → getstream login → retry, CLI missing → paste credentials fallback, seed helpers that exit early if data exists, a v9-vs-v10 version gate that blocks code edits until resolved, and dedicated Verify phases per track.

5 / 5

Progressive Disclosure

The router design is sound (flat references/ naming scheme, one level deep, clearly signaled) and all 16 references/*.md links resolve, but the bundle check shows RULES.md, builder.md, sdk.md, design-matching.md, custom-ui.md, and sendbird-migration.md are all missing — six load-bearing module pointers dangle. Additionally, content that belongs in those modules (the full Step 0.5 credentials/seed procedure, the inlined styling-strategy detail) is kept in SKILL.md itself, so structure is only partially realized.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A model description: concrete actions, an explicit 'Use for' clause, synonym-rich trigger terms, and a distinct niche including a Sendbird-migration trigger. One minor accuracy nit — it advertises stream_feed / stream_feed_flutter_core, which the body flags as deprecated in favor of stream_feeds.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "Build and integrate Stream Chat, Video, and Feeds", "package setup, auth wiring, and widget blueprints", "migrates Flutter apps from the Sendbird Chat SDK" — covering every product lane the skill handles, matching the comprehensive anchor rather than the 'minor gaps' level below.

5 / 5

Completeness

Explicitly answers both: what ("Build and integrate Stream Chat, Video, and Feeds in Flutter apps") and when ("Use for Flutter/Dart project work with Stream package setup, auth wiring, and widget blueprints"), with concrete trigger phrases — the exact anchor-5 pattern.

5 / 5

Trigger Term Quality

Natural trigger terms are comprehensive and include synonyms: "Flutter apps", "Flutter/Dart project work", "Chat", "Video calling and livestreaming", "Activity Feeds", "Sendbird Chat SDK", plus the exact package names (stream_chat_flutter, stream_video_flutter, sendbird_uikit) users cite. Not level 4 because no common user phrasing for this domain is missing.

5 / 5

Distinctiveness Conflict Risk

Clear niche (Stream SDKs in Flutter) with distinct triggers; vendor and package names make conflict with generic Flutter or chat skills minimal.
