Conciseness

Dense and assumes TypeScript/interface competence without padding; however the Common Issues section repeats guidance already in the Critical section (trackUsage, model param), so minor trimming is possible.

Actionability

Provides a full copy-paste class implementation, exact edit locations (line numbers), and executable verification commands ('npx tsc --noEmit', 'npm run test -- src/llm/__tests__/...') covering the common cases.

Workflow Clarity

Steps 1-7 are clearly sequenced and each ends with an explicit 'Verify:' checkpoint, while the Common Issues section supplies feedback loops for error recovery (e.g. 'Unknown provider' cause/fix).

Progressive Disclosure

Well-organized into Critical, Instructions, Examples, and Common Issues sections with no nested references, but everything (~240 lines) is inlined in a single file with no bundle files or one-level-deep references that could offload the Examples/Common Issues detail.

Specificity

Names concrete actions — 'implementing LLMProvider interface with call() and stream() methods', 'provider factory', 'config detection', 'error handling via tracking and recovery' — but 'tracking and recovery' is slightly abstract, leaving minor gaps vs the comprehensive anchor 5.

Completeness

Explicitly answers both what ('Adds a new LLM provider implementing LLMProvider interface with call() and stream() methods') and when ('Use when adding a new model backend...'), with concrete trigger phrases.

Trigger Term Quality

'Use when adding a new model backend, integrating a third-party LLM API, or extending LLM platform support' gives good natural-term coverage, though a few common variations (e.g. 'LLM integration', 'new API provider') are missing.

Distinctiveness Conflict Risk

A clear niche (adding new providers) with explicit negative boundary — 'Do NOT use for fixing bugs in existing providers, modifying existing provider behavior, or changing the LLMProvider interface' — minimizes conflict risk.
