testland/aws-sam-local-testing

Wraps AWS SAM (Serverless Application Model) Local CLI for testing Lambda functions locally: `sam local invoke` (single invocation with event payload), `sam local start-api` (local API Gateway emulator), `sam local start-lambda` (local Lambda invoke endpoint for AWS SDK clients), and event-payload generation (`sam local generate-event`). Use when testing Lambda + API Gateway + integrated AWS services locally.

Content

85%

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

A well-structured, highly actionable skill body with executable examples, clear workflow sequencing, and clean organization. The main weakness is embedded version pins and a slightly explanatory overview that could be tightened.

Suggestions

Move or generalize version-sensitive pins (actions/checkout@v5, aws-actions/setup-sam@v2, '1.x or higher') into a version-tolerant form or a dedicated 'version notes' section so they don't decay or bloat the conciseness score.

Tighten the Overview paragraph about Docker runtime mirroring to only what affects testing decisions, or fold it into the Limitations section where Docker overhead is already discussed.

Consider splitting the CI integration example into a references/ file if the skill grows, to keep the main body a lean overview.

DimensionReasoningScore

Conciseness

Mostly lean and action-oriented, but carries time-sensitive version pins ('actions/checkout@v5', 'aws-actions/setup-sam@v2', 'sam --version # 1.x or higher') outside any deprecated/old-patterns section, plus a mildly explanatory Overview paragraph on Docker runtime mirroring.

2 / 3

Actionability

Provides fully executable, copy-paste-ready guidance throughout: install commands, a complete template.yaml, generate-event invocations, sam local invoke/start-api/start-lambda, a boto3 client snippet, a pytest integration example, and CI yaml.

3 / 3

Workflow Clarity

Clear build→invoke→assert sequence in 'Running', with pytest assertions serving as explicit validation and the Anti-patterns table acting as a checklist of failure modes and fixes.

3 / 3

Progressive Disclosure

No bundle files exist; the single SKILL.md is well-organized into clearly signaled sections with one-level-deep references (external AWS docs URLs and named companion/sibling skills), with no nested reference chains.

Description

100%

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 names concrete capabilities, includes an explicit 'Use when' trigger, and stays in a distinct niche with natural trigger terms. No verbosity or over-claims.

DimensionReasoningScore

Specificity

Lists multiple concrete actions with clarifying detail: 'sam local invoke (single invocation with event payload)', 'sam local start-api (local API Gateway emulator)', 'sam local start-lambda (local Lambda invoke endpoint for AWS SDK clients)', and 'event-payload generation (sam local generate-event)'.

3 / 3

Completeness

Clearly states what it does (wraps SAM Local CLI for the four sub-commands) and gives an explicit 'Use when testing Lambda + API Gateway + integrated AWS services locally' trigger, satisfying both what and when.

3 / 3

Trigger Term Quality

Covers natural terms a user would say when needing this skill — 'testing Lambda functions locally', 'Lambda + API Gateway + integrated AWS services' — alongside the concrete sam local sub-command names.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche (AWS SAM Local Lambda testing) with distinct triggers and third-person voice ('Wraps', 'Use when'), unlikely to fire for non-SAM or non-Lambda skills.
