Conciseness

The body is dense, imperative, and free of explanations of concepts Claude already knows, but step 2.8 and step 7.6 each pack a dozen-plus conditionals into single run-on paragraphs, and warnings repeat (e.g., "Do not retry or work around the refusal" appears in both step 8.1 and 8.2). Not 5: these sections could be tightened or tabulated without losing operational content; not 3: there is no genuinely unnecessary explanation — every rule is Tessl-specific edge-case handling.

Actionability

Guidance is fully executable: exact commands with flags ("tessl project repair --json", "gh repo view --json isFork,parent"), exact JSON fields to read ("linkedProject.workspaceName", "repository.attentionReason"), branch-name conventions, and verbatim questions to ask the user. Not 4: no gaps — common cases (fork, no tessl.json, uncommitted changes, missing app install) each have a specific prescribed response.

Workflow Clarity

Nine clearly sequenced steps with explicit validation checkpoints and feedback loops: re-run doctor after fixes, re-check the GitHub App after the user installs it, verify the remote tessl.json "reflects the whole submitted change" before going live, run the setup hook twice in a fresh clone, and "[confirm the Loops appear]" before declaring setup finished. Destructive actions (push, merge) are gated on explicit user consent, and refusals have prescribed fallbacks.

Progressive Disclosure

The body is a well-organized overview with clearly signaled one-level-deep references (starters, progress, testing, setup-hook, cli-version, links, customize, confirm-loops), all of which exist as real files. Not 5: references/linear.md and references/triggers.md exist in the bundle but are never linked from SKILL.md (linear is only hinted at via a command, not the file), and the ../prepare-repo/SKILL.md link does not resolve within this bundle — minor navigation gaps.

Specificity

"Set up, explain, or change a Tessl factory on a repository" plus five concrete automation examples ("triaging new tickets, shipping tickets as pull requests, keeping pull requests moving, reviewing code, or running a job on a schedule") gives multiple specific actions with comprehensive coverage. Not 4: no meaningful gaps in capability coverage; every clause names a concrete action.

Completeness

Explicitly answers both questions: the first sentence states what the skill does, and "Use when..." gives concrete trigger phrases for when to use it. Not 4: the "when" clause is fully explicit with multiple concrete triggers, not merely present.

Trigger Term Quality

"Use when someone wants Tessl agents to do work in their repo, asks what a factory is or what theirs does, or wants to add to, change, or customize it" captures natural user phrasings well. Not 5: misses common synonyms such as "automations", "bots", or "automate my repository" that users would equally say.

Distinctiveness Conflict Risk

The Tessl-specific niche ("Tessl factory", "Tessl agents") with brand-anchored triggers makes confusion with any other skill very unlikely. Not 4: no realistic overlap scenario exists with closely related skills.
