Constructor Pattern (RULE ZERO). Zero behaviour change, zero flag
drift — all original CLI flags preserved verbatim.
Before: install.sh — 1238 LOC monolith
After: install.sh — 138 LOC dispatcher (sources libs in order)
install/lib-*.sh — 16 cubes, max 183 LOC (lib-menu)
Cubes:
lib-log 21 LOC — logging primitives
lib-backup 63 LOC — rollback trap + BACKUP_PAIRS
lib-profile 115 LOC — MANIFEST.toml profile resolution
lib-args 92 LOC — CLI parsing + --help heredoc
lib-menu 183 LOC — whiptail/dialog/plain-text interactive picker
lib-plan 150 LOC — dry-run --no-execute output
lib-prereqs 91 LOC — hard + soft dependency checks
lib-primitives 131 LOC — primitive copy + MANIFEST drive
lib-rust 114 LOC — cargo workspace build + pre-built support
lib-scaffold 144 LOC — agent/skill/block scaffolding
lib-bridges 31 LOC — project-bridge install
lib-hooks 104 LOC — settings.json jq merge
lib-agents 77 LOC — assembled agent output
lib-skills 23 LOC — skill copy
lib-wizard 20 LOC — sleep-setup wizard invocation
lib-summary 59 LOC — post-install summary
Invariants preserved:
- macOS bash 3.2 compat (no associative arrays, no [[ ]], no ${,,})
- rollback trap wired via setup_backup_trap early in dispatcher
- jq-merge behaviour verbatim in lib-hooks
- scoped Cargo.toml regeneration in lib-rust
Function LOC limits: largest non-heredoc fn 22 LOC (check_soft_prereqs).
Three functions kept >30 LOC because heredoc-dominated (print_help,
print_summary, profile_members); splitting would fragment logical unit.
62 unique function names across cubes, zero duplicates (grep-verified).
bash -n passes on all 17 files. Runtime smoke test deferred to user's
shell (bash-readonly sandbox constraint).

# KeiSeiKit — Constructor-Pattern Agent Kit installer
|
|
# Idempotent: safe to re-run. Never overwrites settings.json or existing user manifests.
|
|
#
|
|
# Usage:
|
|
# ./install.sh # interactive menu on TTY; profile=minimal on non-TTY
|
|
# ./install.sh --profile=<name> # minimal|core|frontend|ops|dev|mcp|full (skips menu)
|
|
# ./install.sh --add=<name>[,<name>] # install one or more primitives on top of current state
|
|
# ./install.sh --remove=<name> # remove a single primitive
|
|
# ./install.sh --list # list installed primitives (name | kind | desc | path)
|
|
# ./install.sh --with-bridges # also render cross-tool bridges into $PWD
|
|
# ./install.sh --activate-hooks # jq-merge settings-snippet.json into ~/.claude/settings.json
|
|
# ./install.sh --yes # skip confirm screen after menu (automation)
|
|
# ./install.sh --no-execute # parse menu+confirm, print plan, exit (testing)
|
|
#
|
|
# Internals: this file is a thin orchestrator. All implementation lives in
|
|
# install/lib-*.sh cubes (Constructor Pattern: 1 file = 1 concern, <200 LOC).
