Conciseness

The body is efficient throughout — commands, a paste-ready JSON config, a compact command table, and bullet lists with no explanation of concepts Claude already knows. It falls short of the 5-anchor because of time-sensitive literals (pnpm@10.11.0, minimax/minimax-m2.7, a hardcoded createdAt) that are not isolated in a deprecation/version section, plus small trims like the placeholder test-script.ts example.

Actionability

Fully executable, copy-paste-ready guidance: exact build commands with corepack workarounds, a complete settings.json to paste, the launch command, a TUI command table, the vitest command, and a 5-step isolation test recipe with exact prompt wording. Not a 4 because there are no meaningful gaps — the common cases (build, configure, launch, test) are all covered with runnable commands.

Workflow Clarity

Prerequisites → provider config → launch → test scenarios → common issues is clearly sequenced, with explicit validation checkpoints ('Verify the status bar at the bottom shows the correct model', 'Verify tasks visible') and stated expected outcomes for each step ('should completely disappear', 'should restore correctly'). Feedback loops for error recovery are present (--continue for DTS build failures, pnpm build:core for test failures, /models re-activation for a wrong status bar).

Progressive Disclosure

No bundle files exist, and the ~138-line body is well organized into clearly labeled sections with no nested references. It is not a 5 because the ~30-line OpenRouter settings.json and the programmatic-rendering methodology are self-contained topics that could live in one-level-deep reference files, and the skill exceeds the under-50-line simple-skill exception.

Specificity

The description names the domain ('Testing mastracode TUI features interactively in Konsole') and enumerates coverage areas ('model configuration, thread lifecycle, task state isolation, and common blockers'), but these are topics rather than concrete executable actions like the 5-anchor's 'extract text, fill forms, merge documents'. It sits between the 2-anchor (minimal/generic actions) and the 4-anchor (several specific actions with minor gaps).

Completeness

The 'what' is clear (interactive testing of mastracode's TUI in Konsole with its covered areas), but there is no 'Use when...' clause or equivalent explicit trigger guidance, which per the judging guidelines caps completeness at 3. It is not a 2 because the 'what' is concrete and multi-part, not vague.

Trigger Term Quality

Relevant keywords like 'mastracode', 'TUI', 'Konsole', 'thread lifecycle', and 'task state isolation' are present, but common natural variations a user would say ('test', 'debug', 'terminal UI', 'rendering') are missing. This matches the 3-anchor ('some relevant keywords but missing common variations or synonyms') rather than the 4-anchor's good coverage.

Distinctiveness Conflict Risk

'mastracode' combined with 'TUI' and 'Konsole' carves out a clear niche with distinct triggers and minimal conflict risk — no other plausible skill would claim this territory. The 4-anchor (minor overlap risk with closely related skills) doesn't apply since nothing closely related is implied.
