Conciseness

The ~30-line body is dense directives with no padding and no explanation of concepts Claude already knows; only minor tokens are questionable, such as the ask_tool_description definition of what a tool is and repeated ALWAYS-style meta-rules across both units — fitting the efficient-with-minor-trimmings anchor rather than the lean-every-token-earns-its-place anchor.

Actionability

The pdsl block is pseudocode rather than executable code, with concrete intent (LOAD required-bootstrap.md, RUN RequiredBootstrap, load implement.md as controlling protocol) but an unresolved placeholder ({cf-studio-path}) and no runnable commands — precisely the pseudocode-with-missing-key-details anchor, not the mostly-executable one.

Workflow Clarity

A two-unit sequence exists (bootstrap before any target workflow, then treat implement.md as controlling protocol) with traversal rules and a stop condition ("ALWAYS stop if any required fragment or rule cannot be followed"), but the actual steps and gates live in external files that are not part of the bundle, leaving checkpoints implicit — anchor 3, not 4.

Progressive Disclosure

References are clearly signaled via explicit LOAD statements, but they point outside the skill bundle ({cf-studio-path}/... with no references/, scripts/, or assets/ directories present), so the load-bearing instructions are unverifiable; the body itself is a flat rule list with no section headers — some structure, but not well-organized navigation, matching anchor 3 rather than 2 (references are not buried) or 4 (references resolve to nothing navigable).

Specificity

The only concrete capability statement is "delegating implementation and review to the core cf-coding engine"; the listed actions ("implement, build, or write the code") are trigger phrasings rather than capabilities, and "Thin preset binding the CODE artifact KIND" is internal jargon, matching the domain-plus-1-2-actions anchor rather than the several-specific-actions anchor.

Completeness

Both parts are present: an explicit when ("Invoke when the user asks to implement, build, or write the code for a FEATURE") and a what ("Thin preset binding the CODE artifact KIND, delegating implementation and review"), but the what relies on unexplained internal terminology ("CODE artifact KIND", "cf-coding engine"), keeping it below the fully explicit anchor.

Trigger Term Quality

Includes natural phrases users would actually say ("implement", "write the code", "build this feature") plus a system-specific trigger ("implement FEATURE with @cpt-* traceability"), but misses common synonyms like "develop" or "create the feature", so it falls short of comprehensive coverage.

Distinctiveness Conflict Risk

Triggers like "implement" and "write the code" would match almost any coding skill, giving real overlap risk, but the "@cpt-* traceability" and "cf-coding engine" markers carve a distinct niche within the cf ecosystem, fitting the somewhat-specific anchor rather than the very-broad one.
