Conciseness

Every sentence carries skill-specific information Claude could not infer — trigger conditions ('version.Current, the pinned SDK, or a resource override or acceptance file'), exact commands, and CI rationale ('CI checks each package version and compares regenerated output with committed files on every PR'). There is no padding and no explanation of concepts Claude already knows; even the 'Why' section earns its tokens by justifying the verification requirement. Nothing needs trimming, so anchor 4 does not apply.

Actionability

Provides two fully executable commands — 'Run `go generate ./internal/provider/` from the provider root' and 'Run `bash tools/iac-codegen/scripts/check-generated-resources.sh`' — plus concrete file targets ('versions.yaml', 'internal/provider/codegen.go'), matching anchor 4 ('mostly executable guidance with minor gaps'). It falls short of anchor 5's copy-paste-ready coverage because the file containing 'version.Current' is never named, and 'Review every generated package, versions.yaml, registry, example, and affected documentation page' does not say what review entails or what 'the registry' is.

Workflow Clarity

The 'Fix' section lays out a discernible sequence (bump version → generate → review outputs → add codegen.go entries → include output in the change → verify) with an explicit validation step ('Run bash tools/iac-codegen/scripts/check-generated-resources.sh after the change is committed to verify the full result'), so the batch-operation cap at 3 does not apply — validation is present. It falls short of anchor 5 because there is no error-recovery feedback loop (nothing says what to do when the check fails) and the sequence is prose rather than an explicitly ordered or checklist form; it is above anchor 3 because a clear checkpoint is explicitly stated.

Progressive Disclosure

The skill is under 50 lines, self-contained, and needs no external references, and the body is organized into clearly labeled sections ('Trigger', 'Fix', 'Why') — per the rubric guideline, short skills with no need for external references score 5 with just well-organized sections. No bundle files exist, so there are no buried or nested references to penalize; this is not anchor 4, which requires 'minor organization gaps' that are absent here.

Specificity

Names the domain ('tools/iac-codegen', 'Terraform resource') and exactly two concrete actions — 'Regenerate every listed Terraform resource and verify committed output' — which matches anchor 3 ('1-2 concrete actions, but not comprehensive'). It falls short of anchor 4's 'several specific actions' because steps the skill actually performs (bumping version.Current, adding codegen.go entries, running the check script) are absent.

Completeness

Both parts are explicit: what — 'Regenerate every listed Terraform resource and verify committed output'; when — 'Use when changing tools/iac-codegen behavior or its version', a concrete trigger phrase naming the exact tool and change types. This mirrors the anchor-5 example's 'Use when X. Do Y and Z.' structure; anchor 4's complaint ('when could be more explicit or specific') does not apply since the when-clause is maximally explicit for the triggers it names.

Trigger Term Quality

'changing tools/iac-codegen behavior or its version', 'Regenerate', and 'Terraform resource' give good keyword coverage of what a user in this repo would naturally say, matching anchor 4 ('good keyword coverage; a few natural terms missing'). It is not anchor 5 because common variations such as 'generated resources', 'SDK', or 'provider' are missing, and not anchor 3 because multiple relevant, natural keywords are present rather than just one generic term.

Distinctiveness Conflict Risk

'tools/iac-codegen' and 'Regenerate every listed Terraform resource' carve out a clear niche with distinct, tool-specific triggers; virtually no other skill would match this regeneration workflow, so conflict risk is minimal — a direct match to anchor 5. It is well above anchor 4's 'minor overlap risk with closely related skills' since no closely related skill domain is named.
