Conciseness

The prose is dense rule statements with no padding about concepts Claude already knows, but there is noticeable tightening opportunity: "[spec-loop-write-adr/SKILL.md]" is cited four times in one section, the phrase "current task, or the current subtask plus any required shared context" recurs across sections, and the Living Project Documents / Glossary sections restate the same ask-before-acting rule in several variations. Not anchor 4 because the repetition goes beyond minor trimmable instances.

Actionability

Concrete, executable instruction-style guidance throughout: specific non-triviality tests ("spans multiple files and is not a straightforward mechanical edit", "changes public or shared APIs"), explicit defaults ("use `tasks/` as the default task directory"), specific file names ("glossary.adoc and glossary.md"), and unambiguous stop conditions ("If readiness or the referent is unclear, ask"). Minor gaps remain because task-format details are delegated to other files, so this is not anchor 5.

Workflow Clarity

A coherent pipeline is present (first classification → planning-form selection → clarification gate → current-first detailed planning → form-specific handling → execution approval) with explicit checkpoints ("Starting EXECUTION requires explicit user approval", "If drafting later exposes an important open decision, stop and clarify"). It falls short of anchor 5 because the sequence must be assembled across separate sections rather than being laid out as one ordered flow, and error-recovery guidance is scattered.

Progressive Disclosure

The body works as a router with clearly signaled, one-level-deep references ("read [planning-form-selection-guidance.md](planning-form-selection-guidance.md) fully", "follow it together with [common-task-guidance.md](common-task-guidance.md)"). Not anchor 5: the referenced local guidance files (planning-form-selection-guidance.md, common-task-guidance.md, chat-only-path-guidance.md, task-file-path-guidance.md, scenario-and-glossary-guidance.md) are not present in the provided bundle to verify, and substantial policy detail (Living Project Documents, Glossary policy) is inlined in the router file.

Specificity

Concrete actions are enumerated: "Choose the planning form for new work and plan it before execution", "decide whether the work is taskless, chat-only, a task file, a task file with subtasks, or multiple task files / backlog items", and "create the needed plan". It stops short of anchor 5 because coverage is limited to classification and plan creation with no hint of what the skill does downstream (e.g., approval gating or execution hand-off).

Completeness

It explicitly answers both questions: the what ("Choose the planning form for new work and plan it before execution") and the when ("Use this skill to decide whether the work is taskless, chat-only... for non-trivial implementation work or investigation work that needs its own task"), with concrete trigger conditions stated rather than merely implied.

Trigger Term Quality

Good natural keyword coverage: "plan", "planning", "task", "task file", "subtasks", "backlog items", "implementation work", "investigation work". A few common user phrasings are missing (e.g., "break down the work", "spec out", "organize this into tasks"), which keeps it below anchor 5.

Distinctiveness Conflict Risk

The enumerated planning forms ("taskless, chat-only, a task file, a task file with subtasks, or multiple task files / backlog items") form a distinct niche, but generic terms like "plan" and "task" carry minor overlap risk with general task-management or planning skills, so it is not anchor 5.
