Conciseness

Mostly lean and dense with executable code and minimal prose — no padding explaining concepts Claude already knows — but there is measurable duplication: tmux key explanations ('Up: History up', 'Tab: Tab completion'), the Dev Mode launcher facts repeated across the Overview table, Dev Mode section, and substitution rule, and a Quick Reference table that restates body commands. Efficient with minor trimming opportunities, matching the 4 anchor rather than 5's 'every token earns its place'.

Actionability

Fully executable, copy-paste-ready commands throughout: launch snippets with exact flags ('MIMOCODE_HOME=$(mktemp -d) mimo run --format json --dangerously-skip-permissions'), jq/grep validation patterns, and five complete runnable scenario functions plus a batch runner. The referenced helper scripts/wait-for-text.sh exists with documented options. Matches the 5 anchor; concrete examples cover the common cases.

Workflow Clarity

Clear sequence (prerequisites → isolated launch → send input → wait-for-text → capture → cleanup) with explicit validation checkpoints everywhere: exit-code checks ('[ $EXIT -eq 0 ] || echo FAIL'), error-event greps, PASS/FAIL assertions per scenario, and a batch runner with a feedback summary. Even the batch operation has explicit verification, so the destructive/batch cap does not apply; this is the 5 anchor.

Progressive Disclosure

Good section structure (Overview, Dev Mode, Parts 1–3, Batch Runner, Quick Reference) and the single bundle file (scripts/wait-for-text.sh) is one level deep and well signaled with a callout explaining how to invoke it. Held at 4 rather than 5 because the ~450-line body inlines material that could be split out (the five scenario test functions, ~90 lines, are candidates for a references or scripts file) and the Quick Reference duplicates body content.

Specificity

Lists multiple concrete actions ('headless `mimo run` with JSON events and interactive TUI via tmux for behavior, integration, and visual regression testing', dev build via `bun dev`) — comprehensive coverage that would merit a 5, but reduced by 1 because it uses second person ('you need to programmatically drive another MiMoCode (mimo) process') instead of third person.

Completeness

Explicitly answers both: what ('Supports headless `mimo run` with JSON events and interactive TUI via tmux') and when ('Use when developing or testing the MiMoCode repository'), plus a concrete do-not-use boundary ('do not use it for ordinary MiMoCode task execution'). Matches the 5 anchor exactly and is above the 4 anchor because the when-clause is explicit, not just present.

Trigger Term Quality

Good natural keyword coverage: 'developing or testing the MiMoCode repository', 'programmatically drive', 'mimo run', 'TUI via tmux', 'integration', 'visual regression testing', 'bun dev'. A few natural phrasings users might say are absent (e.g., 'automate mimo', 'spawn/test a mimo CLI session'), so it sits between the good-coverage (4) and comprehensive (5) anchors, closer to 4.

Distinctiveness Conflict Risk

Clear niche — programmatically driving a separate mimo process for testing — with an explicit negative trigger ('do not use it for ordinary MiMoCode task execution') that sharply reduces mis-triggering against general MiMoCode skills. Minimal conflict risk; clearly the 5 anchor over the 4 anchor's 'minor overlap risk'.
