Conciseness

The body is dense with executable commands and set-expectation callouts with little conceptual padding, matching the level-4 'efficient; minor instances that could be trimmed'. It falls short of level 5 because the troubleshooting decision table duplicates several fixes already explained in the steps, and the time-sensitive version threshold "e.g., < 1.22" sits inline rather than in a dedicated section, which the guidelines penalize.

Actionability

Every step gives copy-paste-ready commands — install scripts, `devenv sync`, `devservices up`, `.venv/bin/sentry upgrade --noinput` — plus concrete verification commands, URLs, and login credentials. The OrbStack section even names the exact source file and grep to locate the bug. This is the level-5 'fully executable, covers the common cases' anchor; level 4 would imply gaps in executable detail.

Workflow Clarity

Steps 1-7 are clearly sequenced with state detection up front and checkpoints like `docker info`, `devenv --version`, and `devenv doctor`. However, the skill contains destructive operations — `make reset-db`, `docker rm -f $(docker ps -aq)`, and the nuclear `devservices purge` — with no validation or confirmation steps around them, which the guidelines explicitly cap at 3 even though the sequence otherwise merits 4-5.

Progressive Disclosure

The single bundle reference (`references/orbstack-fix.md`) is real, one level deep, and clearly signaled from the body ("Read references/orbstack-fix.md for the exact pattern"), and the top-level body uses well-organized sections. It is not level 5 because some OrbStack-socket troubleshooting detail is inlined in Step 6 that would fit better in the existing reference, and no other troubleshooting depth is offloaded despite the long main file.

Specificity

The description lists multiple concrete actions — "Handles fresh setup, updating existing environments, starting dev services, resetting the database, per-worktree environment setup... and troubleshooting" — with comprehensive coverage of the skill's surface. It matches the anchor for multiple specific concrete actions with comprehensive coverage, not the level-4 anchor since there are no meaningful coverage gaps.

Completeness

Both questions are explicitly answered: the 'what' is the full capability list in first sentence, and the 'when' is an explicit "Use when asked to..." clause with concrete trigger phrases. This is the level-5 anchor verbatim in structure; it clearly exceeds level 4, where the 'when' would be less specific.

Trigger Term Quality

Ten quoted natural trigger phrases users would actually say ("set up sentry", "sentry won't start", "devservices not working", "reset the database") plus a catch-all. This matches the comprehensive synonym coverage of the level-5 anchor; it is well above the level-4 anchor's 'a few natural terms missing'.

Distinctiveness Conflict Risk

The Sentry/devenv niche is clear and specific triggers (devenv, devservices, sentry) are distinctive, but the trailing catch-all "or any development environment issue" broadens it to overlap with other dev-environment skills. That is minor overlap risk (level 4), not the level-5 'minimal conflict risk' since a generic dev-env request could route here.
