openspec-update-change

Update an OpenSpec change by revising its existing planning artifacts and keeping them coherent with one another. Use when the user wants to revise a change's plan, fold new decisions into it, or reconcile its artifacts after an edit. Never edits code.

Quality

Content

88%Weight 40%Scale 1-5

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 body with concrete commands, explicit confirm/validate checkpoints, and clear guardrails. The main improvement area is tightening the verbose nested tasks.md rules.

Suggestions

Move the detailed tasks.md requirement-coverage and file-less-task rules into a short reference table or a referenced file to reduce inline bulk in Step 5.

The Guardrails section repeats constraints already stated inline in the Steps; consider consolidating to remove redundancy and save tokens.

Add a one-line note that no bundle files are used, or split the longer operational rules into references/ so SKILL.md stays a lean overview.

Dimension	Reasoning	Score
Conciseness	Largely efficient and assumes Claude's competence, but the nested tasks.md rules (requirement-coverage, file-less-task tags) and some restated guardrails add length that could be trimmed slightly without loss.	4 / 5
Actionability	Provides copy-paste-ready commands with exact flags and JSON field names ('openspec status --change "<name>" --json', 'artifactPaths.<id>.existingOutputPaths') and concrete examples covering the common cases.	5 / 5
Workflow Clarity	A clearly sequenced 6-step workflow with explicit validation/confirm checkpoints ('Write only after the user confirms', 'If the user rejects a revision, do not write it') and feedback loops for error recovery on a write operation.	5 / 5
Progressive Disclosure	Well-organized into clearly headed sections (Store selection, Input, Steps, Output, Guardrails) with no nested external references, though the longer tasks.md subsection is inlined rather than split out.	4 / 5

Description

87%Weight 40%Scale 1-5

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, third-person description that clearly states what the skill does and when to use it with concrete natural-language triggers and an explicit no-code boundary. Minor room for synonyms/alternate trigger phrasings.

Dimension	Reasoning	Score
Specificity	Names the domain (OpenSpec change planning artifacts) and several concrete actions — 'revising its existing planning artifacts', 'keeping them coherent with one another', 'reconcile its artifacts after an edit' — with only minor coverage gaps, fitting just above the 3-anchor.	4 / 5
Completeness	Explicitly answers both what ('Update an OpenSpec change by revising its existing planning artifacts and keeping them coherent') and when ('Use when the user wants to revise a change's plan, fold new decisions into it, or reconcile its artifacts') with concrete trigger phrases.	5 / 5
Trigger Term Quality	Provides natural trigger phrases users would say ('revise a change's plan', 'fold new decisions into it', 'reconcile its artifacts after an edit') but lacks synonyms or alternate phrasings, so it sits at good-but-not-comprehensive coverage.	4 / 5
Distinctiveness Conflict Risk	Clear niche scoped to OpenSpec change-plan revision with an explicit boundary ('Never edits code') and distinct triggers, minimizing conflict with sibling OpenSpec skills like propose/apply/archive.	5 / 5
