firebase-basics

Provides foundational Firebase CLI setup, CLI installation, version checks (`firebase-tools@latest --version`), CLI login (including --no-localhost), project creation, project selection (`firebase use`), and app config file downloads (`google-services.json`, `GoogleService-Info.plist`). Use ONLY for CLI login, project creation/switching, or downloading app config files. Don't use for Firebase Hosting deploy, Firestore, Auth, App Hosting, Data Connect, Crashlytics, or Remote Config.

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

A highly actionable, well-structured CLI skill with concrete commands and clear setup sequencing. Its main weakness is mild verbosity from advisory principles and emphasis noise, plus a minor progressive-disclosure gap around an unreferenced bundle file.

Suggestions

Trim the advisory 'Firebase Usage Principles' that restate general agent behavior (search official docs, use MCP tools, keep skills updated) and consolidate the per-environment setup/refresh link lists into a single reference to reduce token overhead.

Soften redundant emphasis markers (CRITICAL, DO NOT SKIP, NEVER, MUST) — one clear imperative is enough; stacking them adds noise without adding signal.

Add a pointer to references/flutter_setup.md (or remove it from the bundle) so the SDK Setup reference list reflects the actual bundle contents.

Dimension	Reasoning	Score
Conciseness	Mostly command-focused and efficient, but advisory principles ('Prioritize official knowledge', 'Use Firebase MCP Server tools', 'Follow Agent Skills for implementation guidance') and repeated emphasis markers ('CRITICAL', 'DO NOT SKIP', 'NEVER', 'MUST') add padding Claude does not need.	3 / 5
Actionability	Fully executable, copy-paste-ready commands throughout — `npx -y firebase-tools@latest --version`, `login [--no-localhost]`, `use <PROJECT_ID>`, `projects:create`, `apps:sdkconfig ANDROID\|IOS` — with concrete flags covering the common cases.	5 / 5
Workflow Clarity	Clear sequence (environment → auth → active project) with checkpoints (verify version output, confirm 'Active Project', 'MUST pause and ask the developer'), but error-recovery feedback loops are thin and largely deferred to the Common Issues section rather than inline.	4 / 5
Progressive Disclosure	Well-signaled one-level-deep references with stated purposes (firebase-service-init, firebase-cli-guide, web/android/ios_setup, setup/ and refresh/ per-environment files — all verified to exist), but the prerequisites section inlines a long per-environment link list and the bundle's flutter_setup.md is not referenced anywhere.	4 / 5

Description

92%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 strong, specific description that clearly delimits a narrow Firebase-CLI niche with both positive triggers and negative exclusions. Slight room for improvement only in user-natural synonym coverage.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions — 'CLI installation, version checks', 'CLI login (including --no-localhost)', 'project creation', 'project selection (`firebase use`)', 'app config file downloads (`google-services.json`, `GoogleService-Info.plist`)' — with comprehensive coverage of its niche.	5 / 5
Completeness	Explicitly answers both 'what' ('Provides foundational Firebase CLI setup...config file downloads') and 'when' ('Use ONLY for CLI login, project creation/switching, or downloading app config files') with concrete trigger phrases.	5 / 5
Trigger Term Quality	Good natural-term coverage ('Firebase CLI', 'login', 'project creation', 'firebase use', the two config file names), but phrasing is CLI-centric rather than spanning user-natural synonyms like 'set up Firebase' or 'log in to Firebase', so it sits just below the comprehensive-synonym anchor.	4 / 5
Distinctiveness Conflict Risk	Clear niche (Firebase CLI basics) with explicit negative boundary guidance ('Don't use for Firebase Hosting deploy, Firestore, Auth, App Hosting, Data Connect, Crashlytics, or Remote Config') that minimizes conflict with sibling Firebase skills.	5 / 5
