Conciseness

Lean and mostly efficient with concrete commands and little padding; the opening definitional line and a few justifications are useful but slightly more than the bare minimum a competent Claude would need.

Actionability

Fully executable, copy-paste-ready commands throughout (go test -run=... -timeout 60m, TF_ACC=1, grep -rn os.Getenv, -count=1, -v, TF_LOG=debug, TF_ACC_WORKING_DIR_PERSIST=1) covering the common run/diagnose/flip cases.

Workflow Clarity

Multiple clearly sequenced workflows with cumulative ordered diagnose steps and a flip workflow containing an explicit validation/feedback loop; the main run workflow lacks an explicit verify-success checkpoint, keeping it just below 5.

Progressive Disclosure

Well-organized into clear single-purpose sections with appropriately hedged cross-skill references ('if available'); no bundle files exist so structure is judged on sectioning alone, which is good but not exemplary.

Specificity

Names the domain ('running acceptance tests for a Terraform provider') and several concrete actions/scenarios (run with TestAcc prefix, missing env vars, diagnose failing/suspiciously passing tests), with only minor coverage gaps.

Completeness

Clearly states both what ('Guide for running acceptance tests for a Terraform provider') and when ('Use this when asked to run an acceptance test... when a test fails... or when diagnosing...') with concrete trigger phrases.

Trigger Term Quality

Strong natural trigger phrases ('run an acceptance test', 'TestAcc', 'test fails with missing environment variables', 'diagnosing a failing or suspiciously passing acceptance test') that a developer would naturally say, though a few synonyms (e.g. 'TF_ACC', 'acc tests') are absent.

Distinctiveness Conflict Risk

The Terraform-provider acceptance-test niche with the TestAcc prefix is highly specific with distinct triggers and minimal conflict risk against other skills.
