Conciseness

The 'Core Concepts' section explains transient-vs-permanent failures, exponential backoff, and jitter — concepts Claude already knows — and Patterns 2/3/4 substantially overlap (Pattern 4 restates 2 and 3 combined), so the body could be tightened despite otherwise efficient code.

Actionability

All examples are fully executable, copy-paste-ready tenacity code with real imports and sensible parameters, covering the common cases (basic retry, exception filtering, status-code retry, and the combination).

Workflow Clarity

As a patterns library there is no fragile multi-step process, and pattern selection is aided by explicit rules ('Never retry: ValueError, TypeError... AuthenticationError... HTTP 4xx (except 429)') plus a Best Practices checklist; the gap is that no guidance tells the reader which pattern to pick when.

Progressive Disclosure

The body keeps core patterns inline and points to a verified, one-level-deep reference ('Detailed sections (starting with `## Advanced Patterns`) live in `references/details.md`. Read that file when the navigation summary above is insufficient.'), which is a well-signaled split that is easy to navigate.

Specificity

Names the domain and lists several concrete capabilities ('automatic retries, exponential backoff, timeouts, and fault-tolerant decorators'), but omits patterns the body itself covers (circuit breakers, rate limiting), which is a minor coverage gap rather than comprehensive.

Completeness

Clearly answers both 'what' ('Python resilience patterns including automatic retries, exponential backoff, timeouts, and fault-tolerant decorators') and an explicit multi-trigger 'when' ('Use when adding retry logic, implementing timeouts, building fault-tolerant services, or handling transient failures').

Trigger Term Quality

Good natural phrasings users would actually say ('adding retry logic', 'implementing timeouts', 'building fault-tolerant services', 'handling transient failures'), but a few common synonyms are missing ('circuit breaker', 'rate limiting', 'network failures').

Distinctiveness Conflict Risk

A clear niche (Python resilience/retry engineering) with distinct trigger phrases; the language and domain are specific enough that it is unlikely to fire for unrelated skills.
