Conciseness

The body is lean for a nine-stage pipeline: each stage gets a copy-paste command, one or two sentences of purpose, and explicit input/output paths, with no explanations of concepts Claude already knows. Tables (scenario-to-stage, key files) are dense and pull their weight, matching the 'every token earns its place' anchor.

Actionability

Every stage has an executable command (npm run capture/generate/build/test/...), concrete file paths (packages/sdk/generated/tools-manifest.json, scripts/ir-schema.ts), and defined inputs/outputs. The scenario table maps real situations to exact starting stages, making the guidance fully copy-paste ready.

Workflow Clarity

The nine stages are explicitly sequenced, with dedicated validation stages (unit, script, E2E, lock validation), an explicit feedback loop ('If this fails with a projection error, go back to Stage 2 and fix domain-map.json'), a warning about Stage 8 ordering relative to Stage 3, and 'When to skip' conditions per stage. This matches the anchor requiring explicit validation steps and error-recovery loops.

Progressive Disclosure

Structure is good: clear stage sections, a quick-reference section, and smart delegation of the only agent-judgment stage to the sibling stitch-sdk-domain-design skill. However, no bundle files exist and reference-like material (the 11-row key-files table and the detailed Stage 9 audit checklist) is inlined in a ~200-line body where a reference file would keep SKILL.md a purer overview, so it sits at 'good structure; minor organization gaps' rather than level 5.

Specificity

The description names the domain ('Stitch SDK generation pipeline') and one concrete action ('Run the full... pipeline'), but does not list the several specific actions involved (schema capture, domain mapping, TypeScript generation, testing). It matches 'Names domain and 1-2 concrete actions, but not comprehensive' rather than the level-4 anchor, which requires several listed actions.

Completeness

It explicitly answers both parts: what ('Run the full Stitch SDK generation pipeline') and when ('Use when a new tool is added, or the SDK needs to be regenerated end-to-end'). Both are concrete and explicit, matching the level-5 anchor's structure of a clear what followed by concrete trigger phrases.

Trigger Term Quality

Natural trigger phrases like 'a new tool is added' and 'the SDK needs to be regenerated end-to-end' are phrases a user would plausibly say, alongside the domain keyword 'SDK'. It falls short of level 5 because common variations such as 'rebuild the SDK', 'update the SDK', or 'tool changed' are missing.

Distinctiveness Conflict Risk

'Stitch SDK generation pipeline' is a clear niche with distinct triggers; no other generic skill (general codegen, testing, or build skills) would plausibly claim these triggers. Conflict risk is minimal.
