guidewire-sdk-patterns

Build a production-grade Guidewire Cloud API client that survives the request-side failures — 409 checksum conflicts on PATCH/PUT, 429 quota throttling, offsetToken pagination drift, retry-unsafe POSTs, and unstructured error responses. Use when designing an HTTP client wrapper around PolicyCenter, ClaimCenter, or BillingCenter REST endpoints. Trigger with "guidewire client", "guidewire sdk", "checksum 409", "guidewire pagination", "guidewire rate limit", "Retry-After".

Quality

Content

76%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.

A strong, code-first SDK-patterns skill with fully executable examples and clean structure; its main weakness is the absence of validation/verification checkpoints in the destructive (PATCH/PUT) and batch (bulk import) workflows, which the rubric caps at 3 for workflow clarity.

Suggestions

Add an explicit validation/feedback loop to the batch import example (Example 2) — e.g. collect failures, verify created-claim counts against the input batch, and retry only the failures — so the destructive/batch workflow clears the workflow_clarity cap.

Surface the references earlier and more prominently (e.g. a 'References' callout after Prerequisites) rather than only in the final sentence of the Error Handling section, to improve navigation signaling.

Tighten the Overview's 'Five production failures' prose so it does not duplicate the per-section rationale that follows each numbered pattern.

DimensionReasoningScore

Conciseness

Mostly efficient: each pattern leads with a tight domain-specific rationale (e.g. 'Every Cloud API resource carries a checksum') that Claude likely does not already know, followed by executable code. The Overview's 'Five production failures' prose and the Error Handling table repeat some of the per-section explanation, which could be trimmed.

4 / 5

Actionability

Every one of the five patterns ships as complete, copy-paste-ready TypeScript (patchResource, backoffFor, paginate, createClaim with Idempotency-Key, GwError/mapError), and the Examples section demonstrates concrete invocations covering the common cases.

5 / 5

Workflow Clarity

The five patterns are clearly numbered and sequenced, and the Error Handling table gives recovery guidance, but the destructive/batch workflows lack explicit validation checkpoints — e.g. Example 2's 10,000-record bulk import loops createClaim with no verification, error aggregation, or feedback loop, which caps this dimension at 3 per the rubric.

3 / 5

Progressive Disclosure

Good structure: SKILL.md is a pattern overview with well-organized sections (Overview, Prerequisites, Instructions, Output, Examples, Error Handling) and one-level-deep references to real files (references/implementation-guide.md, references/API_REFERENCE.md). The references are only signposted in a single sentence near the end rather than prominently, keeping it just below a 5.

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.

The description is precise, third-person/imperative in voice, and clearly answers both what the skill does and when to use it, with a rich set of natural trigger phrases. It is among the strongest examples in the rubric's good_overall set.

DimensionReasoningScore

Specificity

Names five concrete failure-handling actions — '409 checksum conflicts on PATCH/PUT', '429 quota throttling', 'offsetToken pagination drift', 'retry-unsafe POSTs', and 'unstructured error responses' — giving comprehensive, specific coverage rather than generic language.

5 / 5

Completeness

Explicitly states the 'what' ('Build a production-grade Guidewire Cloud API client that survives the request-side failures') and the 'when' ('Use when designing an HTTP client wrapper around PolicyCenter, ClaimCenter, or BillingCenter REST endpoints'), plus a concrete 'Trigger with' clause.

5 / 5

Trigger Term Quality

Provides a broad explicit trigger list — 'guidewire client', 'guidewire sdk', 'checksum 409', 'guidewire pagination', 'guidewire rate limit', 'Retry-After' — covering natural phrases plus the technical synonyms a developer would actually say.

5 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (Guidewire Cloud API clients for PC/CC/BC) with product-specific triggers like 'guidewire sdk' and 'checksum 409', making conflict with unrelated skills minimal.
