$HOOKS_DIR ($HOME/.claude/hooks) is shared with other kits. Backing up
the whole directory cumulatively bloats foreign hooks across re-runs.
Switch to backup_file per KeiSeiKit-owned hook so only the 3 files we
actually overwrite get a .bak-TIMESTAMP sibling. backup_dir remains for
KeiSeiKit-owned directories (_blocks, _templates, _assembler, skills).
say/warn/err now detect isatty(1) and the NO_COLOR env convention. When
stdout is redirected to a log file or NO_COLOR is set, ANSI escape codes
are suppressed. Interactive activation prompt also gated.
Offline build is attempted first so a fresh clone with a warm registry
cache can install without network. On failure, fall back to a regular
cargo build --release which will fetch from crates.io.
Adds --activate-hooks flag for non-interactive hook activation, plus a
TTY prompt at end-of-install. Merge is jq-based, groups by matcher, and
de-dupes hook entries by command — idempotent across re-runs. Existing
user hooks on the same matcher are preserved. Non-TTY without the flag
keeps the manual instructions.
If cargo build or any later step fails, the ERR trap walks the list of
backups created during this run and atomically swaps each .bak-TIMESTAMP
back onto its original. Idempotent via ROLLED_BACK guard. On success
nothing is rolled back — backups remain as the user's recovery copy.
_blocks/memory-protocol.md references ~/.claude/memory/MEMORY.md, but the
installer previously only scaffolded agents/ hooks/ skills/ — so the first
agent that followed the block would fail reading a non-existent index.
Now mkdir -p ~/.claude/memory and, only when MEMORY.md is absent, write a
minimal placeholder (frontmatter + pointer to the block). User-edited
MEMORY.md is never overwritten.
All three hooks used `set -eu` + `cat | jq …`. Without jq installed, jq
would fail and `-e` would abort the hook → non-zero exit → Claude Code
refuses Edit/Write/Bash system-wide. Now each hook probes for jq BEFORE
`set -eu` and exits 0 silently if absent. Also dropped the useless `cat |`
pipe — `jq -r` reads stdin directly.
Companion: install.sh jq check upgraded from warn to hard `exit 1` because
without jq the hooks are dead weight; message states jq is required on
any machine that will activate the hooks.
Previously cp -f clobbered user-edited _blocks/, _templates/, _assembler/,
hooks/, and skills/ silently — violating the README's "idempotent" claim
on re-run. Now each of those targets is snapshotted to a timestamped
<target>.bak-$(date +%s)/ sibling before overwrite, but only when the
target actually contains regular files (freshly-mkdir'd scaffolds are
skipped). _manifests/ unchanged — already uses per-file skip-if-exists.
Kit source ($KIT_DIR) is never backed up.
