Conciseness

The body is mostly lean commands and steps, but the "Artifact Creation Guidelines" section substantially restates step 4a: the context/rules-as-constraints point ("context: Project background (constraints for you - do NOT include in output)") is repeated with three sub-bullets and a second IMPORTANT marker. Not 2 because most of the file is efficient and unpadded; not 4 because the duplication is a whole redundant section, beyond minor trimmable instances.

Actionability

All commands are copy-paste ready (`openspec new change "<name>"`, `openspec status --change "<name>" --json`, `openspec instructions <artifact-id> --change "<name>" --json`), the JSON response fields to parse are enumerated, and edge cases (missing input, unclear context, existing change) are explicitly handled. Deferring artifact content to the CLI's runtime `template` is a justified design, not a gap, so anchor 5 applies.

Workflow Clarity

Clear dependency-ordered sequence with explicit validation checkpoints ("re-run `openspec status`... Check if every artifact ID in `applyRequires` has `status: 'done'`", "Verify each artifact file exists after writing before proceeding to next"), an explicit stop condition, a user-input feedback loop via AskUserQuestion, and TodoWrite progress tracking. Meets anchor 5; the batch-operation validation cap does not apply since validation is present.

Progressive Disclosure

Sections are well organized (Input / Steps / Output / Artifact Creation Guidelines / Guardrails) and no external reference files are needed because all artifact-specific detail is sourced dynamically from the `openspec` CLI. However, the body is ~90 lines in a single file and the Guidelines section duplicates step 4 content — a minor organization gap that keeps it below anchor 5 and comfortably above anchor 3.

Specificity

Names the domain ("OpenSpec artifact creation") and one concrete action ("create all artifacts needed for implementation") but never enumerates which artifacts (e.g., specs, tasks, design docs). Matches anchor 3 (domain + 1-2 concrete actions, not comprehensive); it is not 4 because no several specific actions are listed, and not 2 because it goes beyond a bare domain label.

Completeness

Has both an explicit "Use when..." clause with a concrete trigger condition ("when the user wants to quickly create all artifacts... without stepping through each one individually") and a "what" statement. Not 5 because the "what" ("Fast-forward through OpenSpec artifact creation") is somewhat abstract and could be more concrete; not 3 because the "when" is fully explicit, not weakly implied.

Trigger Term Quality

Includes natural phrases a user would plausibly say ("quickly create all artifacts", "without stepping through each one individually") plus "fast-forward". Not 5 because common synonyms like "generate everything at once" or "skip the walkthrough" are missing; not 3 because coverage is good rather than merely "some relevant keywords".

Distinctiveness Conflict Risk

"OpenSpec" pins a clear niche and "without stepping through each one individually" explicitly distinguishes this skill from a sibling step-by-step artifact workflow. Minimal conflict risk with other skills.
