The description names a domain (routing and planning new work) and some actions (decide the route, create a plan), but the actions are somewhat abstract. Terms like 'taskless', 'chat-only', 'task-file' hint at specific categories but aren't fully explained as concrete actions.

The description clearly answers both 'what' (choose the route for new work and plan it) and 'when' ('Use this skill to decide whether the work is taskless, chat-only, or task-file, and to create the needed plan for non-trivial executable work'). The 'Use this skill' clause provides explicit trigger guidance.

It includes some relevant terms like 'plan', 'new work', 'implementation', and the routing categories ('taskless', 'chat-only', 'task-file'), but these are internal/technical jargon rather than natural terms a user would say. A user is more likely to say 'start a new task' or 'how should I approach this' than use these specific routing terms.

The routing/planning concept is somewhat distinctive with its specific categories (taskless, chat-only, task-file), but 'plan' and 'new work' are broad terms that could overlap with project management or task creation skills. The internal terminology helps differentiate but the overall scope of 'planning before implementation' is fairly broad.

The skill is extremely verbose at ~200+ lines, with significant repetition (route selection criteria are stated multiple times, taskless/chat-only/task-file routes are described redundantly across sections). Many rules restate things Claude would naturally understand (e.g., explaining what phases mean, when to ask questions). The glossary policy section alone adds substantial weight for what could be 2-3 lines.

The skill provides concrete decision criteria and specific prompts to use (e.g., exact phrases like 'This looks trivial. May I do this without a plan?'), which is good. However, there are no executable code examples, no concrete task file templates inline, and much of the guidance is procedural prose rather than copy-paste-ready artifacts. It relies heavily on external files for the actual actionable content.

The phase model (PLAN → IMPLEMENTATION → DONE) is clearly defined with explicit transition rules and validation checkpoints (unresolved-questions scan, clarification before proceeding). However, the overall workflow is fragmented across many sections with overlapping concerns, making it hard to follow the actual sequence. The route selection decision tree would benefit from a clearer flowchart-style presentation rather than scattered bullet lists.

The skill references several external files (common-task-guidance.md, chat-only-path-guidance.md, task-file-path-guidance.md, etc.) which is good progressive disclosure structure. However, without bundle files provided, we can't verify these exist. The main file itself contains too much inline detail that could be pushed to referenced files, and some references are to sibling skill directories (../spec-loop-clarify-task/SKILL.md) creating a multi-level navigation pattern.
