# KeiSeiKit — Constructor-Pattern Agent Kit for Claude Code

KeiSeiKit is a comprehensive drop-in toolkit for [Claude Code](https://claude.com/claude-code). It ships a curated set of composable behavioral blocks, a Rust assembler that builds agent `.md` files from TOML manifests deterministically, six pre-wired hooks, 34 portable skills (including an interactive `/new-agent` wizard and 10 hub-and-spoke pipelines), 9 Rust primitive crates, 13 shell primitives, and 11 cross-tool bridge templates. Everything follows a Constructor Pattern: one file per concern, manifests as single source of truth, and the generated agent files are regenerated on every relevant edit.

The kit is MIT-licensed and fully generic — install it on a fresh machine and you get a sane 12-agent fleet (implementers, critics, researchers, cost-guardians, and more — all namespaced under `kei-*` so they won't collide with your own same-named agents), a wizard for spinning up new project specialists, 10 pipeline skills that combine primitives end-to-end (`/compose-solution`, `/site-create`, `/schema-design`, `/observability-setup`, `/auth-setup`, `/api-design`, `/ci-scaffold`, `/test-matrix`, `/docs-scaffold`, `/new-project`, `/vm-provision`), and a build pipeline that keeps every agent derivable from its manifest.

## Prerequisites

**Hard** (needed for every install, regardless of profile):

- **Rust** (stable toolchain) — the assembler Cargo workspace is always built
- **jq** — used by the shell hooks for JSON parsing (`brew install jq` / `apt install jq`)
- **Claude Code** — the agents, hooks, and skills target Claude Code's agent / skill / hook surface

**Soft** (only needed if the chosen profile pulls the primitive in — see the profile table below):

- **pandoc** — `tomd` uses it for `.docx` / `.pptx` / `.html` (needed for `core` / `full` profile)
- **Node + Playwright** — for the 3 browser-driven frontend primitives `design-scrape`, `live-preview`, `mock-render` (`frontend` / `full` profile); install with `npm i -g playwright && playwright install chromium`
- **sqlite3 CLI** — optional for manual DB inspection of `kei-ledger` / `kei-migrate` (their binaries embed SQLite via `rusqlite`; `ops` / `dev` profile)
- **hcloud / vultr-cli** — wrapped by `provision-hetzner` / `provision-vultr` (`ops` profile)
- **yq v4** (mikefarah/yq Go impl) — required by `kei-ci-lint` (`dev` profile)

`install.sh` checks only the deps relevant to the selected profile and soft-warns once per missing tool.

## Install

```bash
git clone <your-fork-of-this-repo> KeiSeiKit
cd KeiSeiKit
./install.sh                      # profile=minimal (default, no primitives)
```

`install.sh` is idempotent. It:

1. Creates `~/.claude/agents/{_blocks,_manifests,_primitives,_bridges,_templates,_assembler,_generated}`, `~/.claude/hooks`, `~/.claude/skills`
2. Copies all blocks + bridges (overwrites — these are SSoT from the kit)
3. Copies primitives ONLY for the selected profile (default: `minimal` = none). Tracks installed set in `~/.claude/agents/_primitives/.installed`.
4. Copies generic manifests (skips if you already have a manifest with that name)
5. Builds the Rust assembler (`cargo build --release` in `_assembler/`)
6. If any Rust primitive is in the selected profile: writes a scoped workspace `Cargo.toml` listing ONLY the installed crates, then `cargo build --release`
7. Generates agent `.md` files in-place with `AGENT_ROOT=~/.claude/agents assemble --in-place`
8. Copies the six hooks and 34 skills

After install, the only remaining step is merging `settings-snippet.json` into your `~/.claude/settings.json` to activate the hooks. You can do this automatically with `./install.sh --activate-hooks` or answer `y` at the end-of-install TTY prompt.

### Interactive install

Run `./install.sh` with no profile flag on a TTY and you get a menu:

- `whiptail` or `dialog` detected → curses-style TUI (radiolist for profile, checklist for custom)
- neither available → plain-text numbered picker (`1-7` + a `custom` option)

After the profile is chosen, an **Install Plan** screen summarizes what will be copied, which soft-deps are present (`jq`, `pandoc`, `playwright`, `cargo`, `hcloud`, `vultr-cli`, `yq`, `sqlite3`, `curl`), and the rough time + disk footprint — then asks `Proceed? [Y/n]`. Pass `--yes` to skip the confirm screen (the menu still runs). Pass `--no-execute` to parse menu + confirm and exit without copying anything (useful for dry-run). The menu is **skipped automatically** when any selection flag is passed (`--profile`, `--add`, `--remove`, `--list`) or when stdin/stdout is not a TTY (CI runs default to `minimal` exactly as before).

## Install profiles

By default `./install.sh` is **minimal** — agents + hooks + skills + bridges, no primitives. Fastest (~5s) and zero Rust compile for primitives. You opt into primitives via `--profile=<name>` or one-at-a-time via `--add=<name>`.

| Profile | Primitives added | Install time | Disk (approx) |
|---|---|---|---|
| `minimal` (default) | none | ~5s | ~2 MB |
| `core` | `tomd`, `genesis-scan` | ~10s | ~5 MB |
| `frontend` | 8 site tools: `mock-render`, `visual-diff`, `tokens-sync`, `design-scrape`, `live-preview`, `figma-tokens`, `frontend-inspect`, `screenshot-decode` | ~60s | ~80 MB |
| `ops` | 8 infra tools: `kei-ledger`, `ssh-check`, `firewall-diff`, `provision-hetzner`, `provision-vultr`, `harden-base`, `metrics-scrape`, `log-ship` | ~90s | ~50 MB |
| `dev` | 4 dev tools: `kei-migrate`, `kei-changelog`, `kei-ci-lint`, `kei-docs-scaffold` | ~60s | ~40 MB |
| `full` | everything (22 primitives) | ~5 min | ~200 MB |

Examples:

```bash
./install.sh                        # minimal (no primitives)
./install.sh --profile=frontend     # minimal + 8 site tools
./install.sh --profile=full         # everything (old default behaviour)
./install.sh --add=kei-ledger       # add a single primitive on top of current install
./install.sh --add=kei-ledger,ssh-check
./install.sh --add=ops              # a profile name works too — unions its members in
./install.sh --list                 # show each primitive: name | kind | installed? | description
./install.sh --remove=kei-migrate   # remove one (rebuilds scoped rust workspace if needed)
```

Profile resolution lives in `_primitives/MANIFEST.toml` — one `[primitive.<name>]` entry per primitive plus a `[profile]` block. Edit the manifest to define new profiles without touching `install.sh`.

> **Migrating from a full install:** if you're re-running `install.sh` after an earlier version that installed all 22 primitives unconditionally, the new default (`minimal`) will REMOVE them. To preserve the old behaviour explicitly, pass `--profile=full`.

> **Re-install disclaimer:** `install.sh` is idempotent for clean state but **overwrites kit-owned `_blocks/`, `_primitives/`, `_bridges/`, `_templates/`, `_assembler/`, `hooks/`, and `skills/` on re-run** — local modifications under those directories are backed up to `<dir>.bak-TIMESTAMP/` (or, for shared hook files, to `<file>.bak-TIMESTAMP`). User-owned `_manifests/*.toml` are never overwritten.

## What you get

| Category | Count | Examples |
|---|---:|---|
| Behavioral blocks | 73 | `baseline`, `evidence-grading`, `rule-math-first`, `stack-rust-axum`, `stack-react-vite`, `stack-vue-nuxt`, `stack-sveltekit`, `stack-astro`, `deploy-modal`, `api-fal-ai`, ... |
| Generic agents (manifests) | 12 | `kei-code-implementer`, `kei-critic`, `kei-validator`, `kei-security-auditor`, `kei-architect`, `kei-researcher`, `kei-ml-implementer`, `kei-cost-guardian`, `kei-modal-runner`, ... |
| Hooks | 6 | `assemble-agents`, `assemble-validate`, `no-hand-edit-agents`, `tomd-preread`, `agent-fork-logger`, `site-wysiwyd-check` |
| Portable skills | 34 | `compose-solution`, `new-agent`, `new-project`, `site-create`, `schema-design`, `observability-setup`, `auth-setup`, `api-design`, `ci-scaffold`, `test-matrix`, `docs-scaffold`, `vm-provision`, ... |
| Primitives (Rust crates, opt-in) | 8 | `kei-ledger`, `kei-migrate`, `kei-changelog`, `ssh-check`, `firewall-diff`, `mock-render`, `visual-diff`, `tokens-sync` |
| Primitives (shell, opt-in) | 13 | `tomd`, `design-scrape`, `live-preview`, `figma-tokens`, `frontend-inspect`, `screenshot-decode`, `metrics-scrape`, `log-ship`, `provision-hetzner`, `provision-vultr`, `harden-base`, `kei-ci-lint`, `kei-docs-scaffold` |
| Cross-tool bridges | 11 | Cursor legacy/MDC, Codex, Copilot, Windsurf, Junie, Continue, Gemini, Aider, Replit |

Of the 73 blocks, the **8 base blocks** (`baseline`, `evidence-grading`, `memory-protocol`, `rule-pre-dev-gate`, `rule-test-first`, `rule-error-budget`, `rule-double-audit`, `rule-math-first`) are referenced directly by the 12 shipped manifests. The remaining blocks (`stack-*`, `deploy-*`, `api-*`, `scraper-*`, `domain-*`) are a library consumed by the `/new-agent` wizard and the hub-and-spoke pipeline skills: when you compose a project specialist or spin up a site, the wizard / pipeline picks the appropriate blocks and emits artefacts that reference them.

## Creating a new agent

Run the wizard in Claude Code:

```
/new-agent
```

You'll be asked (via multiple option-picker batches, not free-text) — each batch groups several click-only questions into a single `AskUserQuestion` call:

1. Project stack (Rust CLI / axum / SwiftUI / Flutter / FastAPI / Next.js / React-Vite / Vue-Nuxt / SvelteKit / Astro / Go / Embedded / Python ML)
2. Deploy target (local-only / EC2 / Cloudflare / Modal / Docker / none)
3. Uses paid APIs? (Yes / No)
4. Contains ML? (Yes / No)
5. Has credentials? (Yes / No)
6. Uses scrapers? (None / Free-tier / Paid tier)

Then one free-text prompt for slug + description + path + gotchas. The wizard composes the manifest, validates it, assembles the `.md`, and prints a two-step git-commit command you can run or edit first.

## Pipelines

Hub-and-spoke skills that combine primitives into end-to-end flows. Each one is an option-picker-first, free-text-last wizard; every phase has a verify-criterion.

| Skill | One-line purpose |
|---|---|
| `/compose-solution` | Meta-composer: decompose any task, grep prior art, propose math-first architecture, assemble the right artefact (agent / skill / hook / block) |
| `/new-project` | Bootstrap a project specialist agent + repo skeleton + bridges + ledger row |
| `/new-agent` | Interactive 6-question wizard that builds a project-specialist manifest and its `.md` |
| `/site-create` | Frontend stack pick → design tokens → scaffold → WYSIWYD loop (mock-render, visual-diff, tokens-sync) |
| `/schema-design` | DB schema design → migrations → `kei-migrate` apply (PG/SQLite/MySQL autodetect) |
| `/observability-setup` | Pick metrics + logs stack → scrape + ship config (`metrics-scrape`, `log-ship`) |
| `/auth-setup` | Pick auth model (session / JWT / OAuth2) → emit routes + middleware + token rotation |
| `/api-design` | Contract-first: pick REST vs GraphQL vs gRPC, emit types + handlers + tests |
| `/ci-scaffold` | GitHub Actions / Forgejo Actions workflow skeleton + `kei-ci-lint` pre-commit |
| `/test-matrix` | Test stack matrix: unit / integration / e2e / visual; pick stack, emit skeleton |
| `/docs-scaffold` | Doc site skeleton (mdbook / docusaurus / astro-starlight) + `kei-changelog` generator |
| `/vm-provision` | VM provider pick → `provision-*` primitive → `harden-base` + `ssh-check` + `firewall-diff` verification |

All pipelines share a single discovery layer: `/compose-solution` Phase 3's prior-art grep covers `_blocks/`, `_manifests/`, `_primitives/` (shell + Rust), `skills/`, `_bridges/`, `hooks/` — so any pipeline can reuse primitives without re-inventing them.

## Primitives (Rust)

`_primitives/_rust/` is a Cargo workspace with 9 single-binary crates. `install.sh` builds `--release` and drops binaries at `~/.claude/agents/_primitives/_rust/target/release/<name>`.

| Crate | Purpose |
|---|---|
| `kei-ledger` | Agent-fork lifecycle SQLite (`fork` / `done` / `fail`); SSoT for RULE 0.12 |
| `kei-migrate` | Universal DB migration runner — Postgres / SQLite / MySQL autodetect from `DATABASE_URL` |
| `kei-changelog` | Git-cliff-style `CHANGELOG.md` generator from Conventional Commits |
| `ssh-check` | `sshd_config` linter — flags weak ciphers, PermitRootLogin yes, password auth, etc. |
| `firewall-diff` | `ufw` intended-vs-running diff — catches drift between declared policy and live kernel rules |
| `mock-render` | Playwright wrapper — takes screenshots with SHA-locked PNGs (WYSIWYD: What You See Is What You Deploy) |
| `visual-diff` | Pixel diff with tolerance — used in `/site-create` screenshot-regression loop |
| `tokens-sync` | Design tokens JSON → Tailwind config extend + CSS variables under `:root` |
| `genesis-scan` | Patent-IP leak scanner — runs as a git pre-commit or CI gate (complements the `genesis-leak-guard` runtime hook) |

## Primitives (shell)

`_primitives/*.sh` is the shell-primitive layer. Installed at `~/.claude/agents/_primitives/` by `install.sh` with `chmod +x`.

| Primitive | Purpose |
|---|---|
| `tomd` | Universal non-native-format → markdown (PDF, DOCX, XLSX, PPTX, CSV, images with OCR, code) |
| `design-scrape` | Scrape a live URL's DOM + computed styles + asset manifest into a structured JSON blob |
| `live-preview` | `start` / `stop` / `status` dev server wrapper — writes `.keisei/dev-server.pid` for hook discovery |
| `figma-tokens` | Figma API → design tokens JSON (consumed by `tokens-sync`) |
| `frontend-inspect` | Pointer a running dev server, dump DOM tree + accessibility tree + CSS cascade for a given selector |
| `screenshot-decode` | OCR + layout extraction from a screenshot (used when design source is a PNG, not code) |
| `metrics-scrape` | Pull Prometheus / OpenMetrics endpoints, normalize, diff against baseline |
| `log-ship` | Tail structured logs, forward to Loki / CloudWatch / journald with rate limits |
| `provision-hetzner` | Hetzner Cloud API provisioner — server create + cloud-init + ready-wait |
| `provision-vultr` | Vultr API provisioner — same shape as Hetzner |
| `harden-base` | Post-provision baseline hardening — fail2ban, ufw, unattended-upgrades, no-root-ssh |
| `kei-ci-lint` | Pre-commit / pre-push CI lint — runs the minimum-viable checks locally before push |
| `kei-docs-scaffold` | One-shot doc site skeleton emitter (mdbook / docusaurus / astro-starlight) |

## Architecture

```
  Manifest (_manifests/<name>.toml)          <-- source of truth
         |
         |   [assembler/src/*.rs]              <-- Rust binary
         v
  Generated agent (.claude/agents/<name>.md)  <-- regenerated, never hand-edited
         ^
         |                                     [hook: assemble-agents]
  Block edit (_blocks/<block>.md)             <-- triggers rebuild of ALL agents
```

Six hooks enforce the pipeline:

- **`assemble-agents`** (PostToolUse, Write/Edit) — rebuilds the affected agent(s) whenever a manifest or a block changes. No manual rebuild needed.
- **`assemble-validate`** (PreToolUse, Bash) — blocks `git commit` inside `~/.claude` if any manifest fails validation. Keeps the repo in a buildable state at all times.
- **`no-hand-edit-agents`** (PreToolUse, Edit/Write) — refuses edits to any `.md` under `~/.claude/agents/` that starts with the `<!-- GENERATED -->` marker, pointing you at the manifest instead. Override with `AGENT_MIGRATION=1` for emergencies only.
- **`tomd-preread`** (PreToolUse, Read) — auto-converts opaque binary formats (`.docx`, `.doc`, `.xlsx`, `.pptx`, `.csv`) to markdown via the `tomd` primitive and redirects Claude to read the cached `.md` instead.
- **`agent-fork-logger`** (PreToolUse, Agent) — RULE 0.12 advisory: logs every Agent subagent invocation to the `kei-ledger` SQLite DB so the orchestrator can validate the fork bundle. Never blocks; silent no-op if `kei-ledger` is absent.
- **`site-wysiwyd-check`** (PostToolUse, Edit/Write) — on frontend-source edits (`.tsx`, `.vue`, `.svelte`, `.astro`, `.css`, `.html`, `.jsx`, `.ts`) in a project with a live dev server (`.keisei/dev-server.pid`), takes a Playwright screenshot via `mock-render` and diffs against `.keisei/target.png` via `visual-diff`. Advisory-only — drift is reported to stderr, never blocks.

## Adding custom blocks

Blocks are plain markdown in `~/.claude/agents/_blocks/`. To add one:

1. `touch ~/.claude/agents/_blocks/stack-mystack.md` and write the block.
2. Reference it in a manifest's `blocks = [...]` list.
3. The PostToolUse hook rebuilds the affected agent(s) automatically.

Blocks should be 10-50 lines, single-concern, and readable in isolation. If a block exceeds ~60 lines, split it into two.

## Adding custom manifests

Copy `_templates/specialist.toml.template` and fill the placeholders, OR run `/new-agent` and answer the wizard. Either way, the assembler validates the manifest and generates the `.md` on write.

## Agents overview

All kit agents are namespaced under `kei-*` so they won't collide with your own agents (e.g. your personal `validator` or `critic`) living in `~/.claude/agents/`.

| Agent | Role |
|---|---|
| `kei-code-implementer` | Write production code, Constructor Pattern enforced, Test-First discipline |
| `kei-infra-implementer` | Deploy scripts, CI/CD, secrets management, cost-aware paid infra |
| `kei-ml-implementer` | Training scripts, inference code, Modal jobs, exact param counts |
| `kei-critic` | Read-only anti-pattern / bug / security / perf / debt finder |
| `kei-validator` | Fact-checker; verifies API existence, version compat, citations, doc claims |
| `kei-security-auditor` | Risk-classified security audit with variant analysis + supply chain check |
| `kei-architect` | Read-only structural analysis; dep graph, patterns, coupling |
| `kei-researcher` | Generic web + codebase research, evidence-graded findings |
| `kei-ml-researcher` | ML literature, benchmarks, reproducibility, tooling-reuse search |
| `kei-cost-guardian` | Pre-launch GO/NO-GO for paid compute (Modal, AWS, fal.ai, Apify, etc.) |
| `kei-modal-runner` | Modal compute orchestrator with KILL GUARD (never stops running jobs) |
| `kei-fal-ai-runner` | fal.ai image/video/3D generation expert |

## Cross-tool bridges

KeiSeiKit ships 11 verified tool-bridge templates under `_bridges/`. Render them into any project and the same Constructor-Pattern ruleset is visible to every AI coding tool you use — no drift, one source of truth.

**Tools covered:**

| Tool | Output file |
|---|---|
| Cursor (legacy) | `.cursorrules` |
| Cursor (modern MDC) | `.cursor/rules/main.mdc` |
| Codex CLI / Warp / Zed / Antigravity fallback | `AGENTS.md` |
| GitHub Copilot | `.github/copilot-instructions.md` |
| Windsurf | `.windsurf/rules/main.md` |
| JetBrains Junie | `.junie/guidelines.md` |
| Continue.dev | `.continue/rules/main.md` |
| Google Antigravity / Gemini CLI | `GEMINI.md` |
| Aider | `CONVENTIONS.md` + `.aider.conf.yml` |
| Replit Agent | `replit.md` |

**Three ways to generate:**

1. **At install time** — `./install.sh --with-bridges` renders all 11 into `$PWD` after the normal install completes. Skipped if `$PWD` is the KeiSeiKit repo itself.
2. **From the `/new-agent` wizard** — Phase 8 asks click-only whether to generate all 11, just `AGENTS.md`, or skip.
3. **Manually, any time** — `~/.claude/agents/_bridges/emit.sh <project-dir>` (the install copies `_bridges/` into your agent fleet dir). Add `--only <output-path>` to restrict to a single file.

All paths are idempotent: existing bridge files in the project are skipped, never overwritten. See `_bridges/README.md` for the full template→output-path table.

## Meta-composer

`/compose-solution` is the meta-creator: tell it what you want to solve in one free-text paragraph, it decomposes the task, greps existing blocks / skills / manifests / primitives / bridges for prior art, proposes a minimal math-first architecture, and assembles the right artefact — agent, skill, hook, rule, block, or pipeline invocation. Every decision except the intake is a click (option-picker), never free-text.

Example: "I want a hook that blocks `rm -rf ~/` in any Bash call" → Phase 2 decomposes into (pattern-match, severity, event, wiki entry) → Phase 3 greps `hooks/`, `_blocks/`, `_primitives/` for prior art → Phase 5 proposes `hook = PreToolUse:Bash + pattern + exit 2` → Phase 7 hands off to `/escalate-recurrence` with severity and event pre-filled.

Phase 6 is the feedback loop: when a component has no prior art, the skill drafts a new `_blocks/<slug>.md` and — on your click — persists it. Next time `/compose-solution` (or `/new-agent`) runs, that block is discoverable. Every session leaves the kit a little smarter; the report prints `_blocks/` count before → after so the growth is visible.

See `skills/compose-solution/SKILL.md` and its phase files (`phase-1-intake.md` through `phase-7-assemble.md`) for the full 7-phase pipeline.
