Conciseness

The body is dense and operational — routing tables, numbered validation steps, and concrete commands with no concept explanations Claude already knows. It is not 5 because guidance is repeated across sections: the lint commands appear in both Startup Validation and Rules, and task-tracing rules are restated in Supporting skills, Startup Validation steps 8-9, Plan Before Execution, and Rules, which could be consolidated.

Actionability

Guidance is fully executable: copy-paste-ready commands (`npx ai-devkit@latest skill list`, `skill add --built-in`, `lint --feature <name>`, `task list --name <feature> --json`, `<skill-dir>/scripts/check-status.sh <feature-name>`), a complete phase routing table with explicit 'When' conditions, and enumerated backward transitions covering the common failure cases. Nothing remains at the pseudocode or high-level-hint level.

Workflow Clarity

Startup Validation is a numbered sequence with explicit error-recovery feedback loops (missing skill → install → rerun; still missing → stop and report; lint failure → init → rerun), Plan Before Execution gates on user approval, and Backward Transitions define the fix-retry routing for every phase failure mode. The 'Do not claim completion without fresh verification evidence' rule adds an explicit final checkpoint, matching the anchor's validation steps, feedback loops, and checklists.

Progressive Disclosure

The SKILL.md is a genuine overview: it defers all phase detail to the separate dev-* phase skills and keeps the one bundle reference (`scripts/check-status.sh`) one level deep, clearly signaled with its exact invocation and purpose — the file exists and matches the documented usage. Sections are well organized with no content inlined that belongs in a separate file, fitting the 'clear overview with well-signaled one-level-deep references' anchor.

Specificity

The description names the domain ("structured SDLC phase skills") and one or two concrete actions ("run the full lifecycle or choose the next phase") but "Orchestrator" is an abstract role with no further concrete capability enumerated. It fits the anchor 'Names domain and 1-2 concrete actions, but not comprehensive' — not 4 because it lacks the several specific actions of the 4 anchor, and not 2 because it goes beyond merely naming the domain.

Completeness

It explicitly answers both questions: what ("Orchestrator for structured SDLC phase skills") and when ("Use when the user wants to run the full lifecycle or choose the next phase across requirements, design, planning, implementation, testing, and review") with concrete trigger phrases. It is not the 4 anchor because the 'when' clause is already explicit and specific rather than needing more detail.

Trigger Term Quality

Natural phrases like "run the full lifecycle", "choose the next phase", and the phase names "requirements, design, planning, implementation, testing, and review" give good keyword coverage a user would plausibly say. It falls short of the 5 anchor because common variations such as "software development lifecycle" spelled out, "dev process", or "what's the next step" are missing; it clears the 3 anchor because coverage is broad, not partial.

Distinctiveness Conflict Risk

The "AI DevKit" and orchestrator/lifecycle framing carves a mostly distinct niche, but trigger terms like "requirements", "testing", and "review" overlap with the closely related per-phase skills it routes to (dev-requirements, dev-testing, dev-review). This matches 'Mostly distinct; minor overlap risk with closely related skills' rather than the 5 anchor's minimal conflict risk.
