Conciseness

The body is dense and assumes competence — exact config keys (channel.worker_guard.idle_timeout, codex.dispatch_mode), CLI flags, and file paths with no basic-concept padding. However, the v0.6 overview paragraph ("Trellis v0.6 adds three architectural surfaces...") substantially restates details that reappear in the 'Current Rules' bullets and reference descriptions, so some tightening is possible — the 4 anchor rather than the lean 5 anchor.

Actionability

Fully executable guidance throughout: a conditional routing workflow ('If the request involves a specific AI tool, read references/platform-files/platform-map.md'), copy-paste-ready commands (trellis workflow --template <id>, task.py create --parent <slug>, trellis channel spawn --agent <name>), and exact knobs with their values (codex.dispatch_mode: inline | sub-agent). For a navigation/meta skill this covers the common cases completely.

Workflow Clarity

The 5-step 'How To Use' is clearly sequenced with conditionals, and includes explicit validation checkpoints: step 5 'Before editing, read the actual files in the user project and treat local content as authoritative', plus Do-Not guards against destructive overwrites ('check .trellis/.template-hashes.json first and prefer .new sidecar files') and a verify-before-claim loop ('cross-check against the local .trellis/config.yaml and the installed CLI's trellis --help before claiming a knob exists').

Progressive Disclosure

A clear overview that routes to 22 well-signaled, one-level-deep reference files organized into three labeled groups, each with a one-line description, and every referenced path verified to exist on disk (references/local-architecture/, platform-files/, customize-local/). The 'How To Use' section doubles as a navigation index; content is appropriately split between the inline core rules and the reference files.

Specificity

"Understand and customize the local Trellis architecture" uses only two generic verbs, but the description enumerates many concrete surfaces — ".trellis plus platform hooks, settings, agents, skills, commands, prompts, workflows, the channel runtime (trellis channel), bundled runtime agents under .trellis/agents/" — with named CLI commands and bundled skills. Not 5 because the actions themselves remain abstract (understand/customize) rather than the multiple distinct concrete actions of the 5 anchor; clearly above the 3 anchor's '1-2 concrete actions' coverage.

Completeness

Explicitly answers both: what ("Understand and customize the local Trellis architecture inside a user project") and when ("Use when modifying .trellis plus platform hooks, settings, agents, ... or AI-facing bundled skills ... and bundled-skill auto-dispatch flow"). Matches the 5 anchor's clear what-and-when with concrete trigger phrases.

Trigger Term Quality

Comprehensive natural-term coverage including synonyms and identifiers users would actually say: hooks, settings, agents, skills, commands, prompts, workflows, workflow templates, cross-session memory, plus exact CLI names (trellis channel, trellis mem, trellis init) and file paths (.trellis/, .trellis/agents/). Matches the 5 anchor's standard of synonyms and concrete extensions/paths.

Distinctiveness Conflict Risk

The Trellis-local-customization niche is clear and highly distinct from generic skills, with concrete trigger identifiers. However, the description deliberately claims territory that overlaps closely related bundled skills it names itself — e.g. "cross-session memory (trellis mem)" is also the domain of the bundled trellis-session-insight skill — creating minor overlap risk, which fits the 4 anchor better than the minimal-conflict 5 anchor.
