Conciseness

Mostly efficient — the content is dense, project-specific tables and commands Claude could not know — but it could be tightened: the QA loop is described three times (Build Flow step 4, the QA Loop diagram, and the QA Fixer section), thinking-token values are stated three times (roles table, code comment, Extended Thinking section), and hard-coded dated model IDs (claude-opus-4-5-20251101) are time-sensitive information not placed in a deprecated/old-patterns section. This sits at anchor 3, short of anchor 4 because the redundancy and stale-prone pins are more than 'minor instances'.

Actionability

Concrete, copy-paste-ready commands throughout — 'python run.py --spec 001', 'tail -f .auto-claude/specs/001-feature/build-progress.txt', 'touch .../PAUSE', 'AUTO_BUILD_MODEL=... python run.py --spec 001' — plus real file paths and JSON structures. Minor gaps keep it from anchor 5: the '--review' flag appears only in the troubleshooting table and not in the Build Options table, and 'security.py' and 'coder_recovery.md' are referenced without paths while core/client.py gets one.

Workflow Clarity

The Build Flow is a clearly sequenced four-phase process with an explicit QA validation checkpoint, and the QA loop is a documented feedback loop (Reviewer -> issues -> Fixer -> re-validate) bounded by 'Max 50 iterations'. Error recovery is addressed concretely via recovery mode, HUMAN_INPUT.md intervention, and diagnostic commands, matching anchor 5's explicit validation steps, feedback loops, and recovery guidance.

Progressive Disclosure

No bundle files exist (no references/, scripts/, or assets/), so this scores the single file's structure: clear section headers in logical order (architecture -> running -> configuration -> monitoring -> artifacts -> QA -> troubleshooting) with a Related Skills section for cross-navigation. It matches anchor 4's good structure with minor gaps — some inline reference material (the sample QA report format and implementation-plan JSON schema) could live in a separate reference file, and inline mentions of core/client.py, security.py, and coder_recovery.md point into project source rather than verified bundle paths.

Specificity

The 'what' is a bare label — "Auto-Claude autonomous build system" — with no concrete actions the skill performs; the only action phrases ("running builds, understanding agent workflow, managing parallel execution") appear in the when-clause, describing user contexts rather than capabilities. This matches anchor 2 ('names the domain but actions are minimal or generic') and falls clearly short of anchor 3, which requires 1-2 concrete actions in the what-statement.

Completeness

Both parts are present: a what ("Auto-Claude autonomous build system") and an explicit when ("Use when running builds, understanding agent workflow, managing parallel execution, or troubleshooting build issues"). It is not anchor 5 because the what is a vague label rather than concrete actions with trigger phrases, and not anchor 3 because the when-clause is fully explicit, not weakly implied.

Trigger Term Quality

Good natural keyword coverage — "running builds", "troubleshooting build issues", "parallel execution", "agent workflow" are phrases a user of this system would plausibly say. It falls short of anchor 5's comprehensive synonym coverage: common variations users would actually utter, such as "spec", "QA loop", "build stuck", "subagent", or "worktree", are missing.

Distinctiveness Conflict Risk

The "Auto-Claude" brand name scopes the skill clearly, and triggers like "parallel execution" and "troubleshooting build issues" are tied to this system. Minor overlap risk remains with the sibling skills it itself lists (e.g., auto-claude-optimization for performance/build issues), matching anchor 4 rather than anchor 5's minimal-conflict niche.
