Parfii-bot df857923d4 feat(primitives): kei-migrate Rust universal migration runner 
Single binary, three backends (Postgres/SQLite/MySQL) autodetected
from DATABASE_URL scheme. Sequential .sql migrations tracked in
_kei_migrations with SHA-256 checksums.

Commands:
  kei-migrate up              — apply pending
  kei-migrate down [n]        — revert last N (requires .down.sql)
  kei-migrate status          — list applied vs pending
  kei-migrate create <name>   — scaffold up+down pair with UTC ts

Constructor Pattern: 10 source files, all <90 LOC, functions <30 LOC.
Deps: sqlx 0.8 (any+postgres+sqlite+mysql, rustls), clap 4, chrono,
sha2, anyhow, tokio.

Tests: 9/9 passing (cargo test, SQLite backend).
Clippy clean: cargo clippy --all-targets -- -D warnings.

Safety features:
- checksum drift detection on applied migrations
- IRREVERSIBLE marker blocks down-revert
- duplicate version detection at scan time
- each migration in its own transaction

README.md

_primitives — first-class building blocks

_primitives/ holds standalone utilities that agents, hooks, and skills (including /compose-solution) depend on. Unlike _blocks/ (behavioral markdown) or _manifests/ (agent TOML), primitives are executable shell programs installed at $HOME/.claude/agents/_primitives/ by install.sh.

Current primitives

Primitive Purpose Invocation
tomd.sh Universal non-native-format → markdown converter (PDF, DOCX, XLSX, PPTX, CSV, images, code). ~/.claude/agents/_primitives/tomd.sh <file>

tomd.sh is ported from the KeiAgent project (user's personal CLI predecessor) bin/keiagent-tomd — same format matrix, KeiSeiKit-style error tags ([tomd]), configurable cache directory (KEISEI_TOMD_CACHE).

Hook integration

hooks/tomd-preread.sh is a PreToolUse(Read) hook that auto-redirects Claude to the converted markdown when a Read targets .docx / .doc / .xlsx / .pptx / .csv. Cached under $KEISEI_TOMD_CACHE (default /tmp/keisei-tomd-cache).

/compose-solution discovery

Phase 3 prior-art sweep greps _primitives/ alongside _blocks/, _manifests/, skills/, _bridges/, hooks/. If a user task involves file-format parsing, the meta-composer surfaces tomd automatically — reuse over rewrite (RULE "No Patching").
