Conciseness

Every section carries library-specific, non-obvious facts ("Two do not: `table.DefaultStyles()` and `filepicker.DefaultStyles()` take no argument", "Key maps are functions now"), and nothing explains what Claude already knows. Time-sensitive version details (v2.2.1 pin, the v2.2-only `tree` package) are confined to the migration and 'Older versions' sections rather than scattered, so no trimming target remains.

Actionability

The spinner program is a complete, copy-paste-ready Go program covering the common case (one bubble wired through Init/Update/View), followed by concrete verification commands (`go vet ./...`, `go build ./...`). The trimmed key/help fragment is explicitly justified by the stated convention ("Go blocks headed `// examples/...` are trimmed from complete programs") with links to the complete sources.

Workflow Clarity

The 6-step workflow ends with an explicit validation checkpoint and feedback loop: "Run `go vet ./...` and `go build ./...`, then run the program in a terminal. If a bubble is frozen, empty, or ignores keys, check Mistakes that cost time, fix, and rerun." The migration path repeats the same validate-and-fix loop ("run `go vet ./...` and `go build ./...` and fix what remains").

Progressive Disclosure

The Components table maps every component group to a real reference file (all 8 files under references/ verified to exist) with a 'Read it for' purpose column, and each reference links back to the main skill — exactly one level deep with clear navigation. The body keeps only the shared contract, one full example, and the index inline, pushing component detail to the references.

Specificity

It enumerates the concrete capabilities ("list, table, viewport, textinput, textarea, spinner, progress bar, filepicker, tree, paginator, timer, stopwatch, help, and key bindings") and concrete actions ("wiring its focus, size, styles, and messages, or migrating v1 bubbles code"). Coverage is comprehensive — no shipped component is omitted — which matches the anchor-5 example rather than the 'minor gaps' anchor 4.

Completeness

Both halves are explicit: the 'what' ("Use the Bubbles v2 component library ... inside a Bubble Tea v2 TUI") and the 'when' ("Use when adding a ready made widget or TUI component ... to a terminal app, wiring its focus, size, styles, and messages, or migrating v1 bubbles code"). The 'when' clause is specific and trigger-phrase-rich, matching the anchor-5 example exactly.

Trigger Term Quality

Natural user phrasings are covered with synonyms ("text input, spinners, scrolling view, file picker", "terminal app", "widget") and, in place of file extensions, the package identifiers users paste ("charm.land/bubbles/v2, charmbracelet bubbles"). No common natural term for a real component is missing, so it sits at the comprehensive anchor 5 rather than anchor 4's 'a few natural terms missing'.

Distinctiveness Conflict Risk

It claims a clear niche (Bubbles v2 widgets inside Bubble Tea) and explicitly fences off the three adjacent skills: "Not for the program loop itself (charmed-bubbletea), raw styling (charmed-lipgloss), or whole forms (charmed-huh)." Conflict risk with sibling TUI skills is minimal, matching anchor 5.
