Conciseness

Mostly efficient but padded: the three-part structure is restated three times ("CRITICAL INSTRUCTION" list, the PART 3 intro, and the closing summary), "KEY RULES TO EMPHASIZE" duplicates the skill deep-dives, and passages like "Every AI session starts with a blank slate" re-explain concepts Claude already knows. The bulk is distinct, useful content, so this is anchor 3 rather than the more heavily padded anchor 2.

Actionability

Provides executable commands (grep for "To be filled by the team", `python3 ./.trellis/scripts/task.py create …`), an 11-file guideline checklist, and verbatim dialogue scripts for Situations A and B. Mostly executable with minor gaps — steps like "Analyze the codebase" and "Investigate and fix the bug" stay abstract — matching anchor 4 rather than fully copy-paste-ready anchor 5.

Workflow Clarity

The Parts 1→2→3 sequence is explicit, examples are numbered ([1/8]…[8/8]), and Part 3 opens with a state-validation checkpoint (grep the spec files, then branch on Situation A vs B) before acting. Anchor 4 rather than 5 because there is no feedback loop verifying the guideline-filling work, and inter-part transitions rely on exhortation ("DO NOT skip any part") instead of checkpoints; no destructive or batch operations, so no cap applies.

Progressive Disclosure

No bundle files exist and the entire ~360-line skill — six skill deep-dives and five real-world examples, material that naturally belongs in reference files — is inlined in one monolith, though with clear section headers. This matches anchor 3 (content that should be separate is inline); it is not anchor 2 because the structure is well organized, and not anchor 4 because nothing is split out into separate files.

Specificity

Lists several specific components — "core philosophy (AI memory, project-specific knowledge, context drift), system structure and command deep-dives, real-world workflow examples, and guideline customization" — with minor gaps. It names topical coverage rather than concrete actions like the anchor-5 example, so it sits at anchor 4.

Completeness

Explicitly answers both questions: the "what" ("Interactive three-part onboarding… Covers core philosophy…, system structure and command deep-dives, real-world workflow examples, and guideline customization") and a concrete "when" ("Use when a new developer joins the project, someone needs to understand the Trellis workflow, or project guidelines need initial setup"). This matches anchor 5; the when-clause is explicit with multiple concrete triggers, not the weaker when of anchor 4.

Trigger Term Quality

Natural trigger phrases include "onboarding", "new team members", "new developer joins the project", "understand the Trellis workflow", and "project guidelines need initial setup", with good synonym coverage. A few natural variants (e.g., "training", "intro to the workflow") are missing, matching anchor 4 rather than comprehensive anchor 5.

Distinctiveness Conflict Risk

"Trellis AI-assisted workflow system" carves out a clear niche and all triggers are Trellis/onboarding-specific, giving minimal conflict risk with other skills. Matches anchor 5; it is more distinct than the minor-overlap case of anchor 4.
