Keybase Style Analysis

Keybase Style Analysis

Extracts and analyzes style objects from all TSX source files. Two phases: extract (slow, produces a persistent JSON snapshot) and analyze (fast, reads the snapshot).

When to use extract

Re-run extract when:

• The snapshot file doesn't exist yet (/tmp/keybase-styles.json)
• You've made significant style changes and want fresh data
• User passes --fresh

Skip extract when:

• The snapshot already exists and changes since extraction are minor

Workflow

Phase 1: Extract (run from shared/)

cd /Users/chrisnojima/go/src/github.com/keybase/client/shared
node scripts/analyze-styles.mts extract --output /tmp/keybase-styles.json

Takes ~10–30 seconds. Writes structured JSON with one entry per style object (styleSheetCreate, platformStyles, and inline JSX style props).

Phase 2: Analyze

Full audit — gaps + new candidates:

cd /Users/chrisnojima/go/src/github.com/keybase/client/shared
node scripts/analyze-styles.mts analyze --input /tmp/keybase-styles.json

Border gaps only:

node scripts/analyze-styles.mts analyze --input /tmp/keybase-styles.json --helper border

Raise the minimum count threshold (default 3):

node scripts/analyze-styles.mts analyze --input /tmp/keybase-styles.json --min-count 5

Interpreting output

Gap detection output

Each line shows a file and line number where an existing helper could be used but isn't, plus the suggested replacement call:

chat/audio/audio-player.tsx:123 (container)
  → ...Kb.Styles.border(Kb.Styles.globalColors.grey, 1, Kb.Styles.borderRadius)

When showing these to the user, group by file and present the top 10–15 highest-value sites. Ask which files they want to migrate first.

New helper candidates output

Shows clusters of border properties that co-occur frequently:

[12x]  borderColor+borderRadius+borderStyle+borderWidth
    borderColor: Kb.Styles.globalColors.black_10 | globalColors.grey
    ...

When recommending a new helper, include: what it would be named, its signature, the number of call sites it would clean up, and 2–3 example current usages vs. the proposed call.

After analysis

• For gap sites: offer to migrate them file-by-file or all at once
• For new helper candidates: present the proposed helper signature and get approval before adding it
• After migrating, run yarn lint && yarn tsc from shared/ to verify
