> **Status: frozen (August 2026).** cavekit is no longer in active development. > Everything below still installs and works, but expect no new features or > fixes. Active development of the family lives in > [caveman](https://github.com/JuliusBrussee/caveman) and > [caveman-browse](https://github.com/JuliusBrussee/caveman-browse). <h1 align="center">cavekit</h1> <p align="center"> <strong>compressed spec-driven development for claude code</strong><br/> <sub>one file · one loop · zero sub-agents</sub> </p> --- ## what this is Plan-then-execute forgets. SDD remembers — but most SDD frameworks bury that value under agent swarms, dashboards, and ceremony that costs more tokens than it saves. Cavekit is the simplest full loop: **grill → spec → research → review → build**, over one `SPEC.md` file, no sub-agents. Three commands you run every time; four more you reach for only when the change earns it. The spine is three properties that earn their tokens: - **durable spec** — `SPEC.md` at repo root survives context resets. It is the agent's long-term memory: lose the window, reload the spec, keep going. - **caveman encoding** — ~75% fewer tokens than prose. Symbols, fragments, pipe tables. All nine skill descriptions cost ~1.1k context — 16× lighter than spec-kit's 18.6k. That is the whole point. - **backprop reflex** — every test failure becomes a `§B` entry; classes of bug become `§V` invariants the spec never forgets. And one rule that keeps it from bloating into the frameworks it replaces: **right-size**. A one-line fix is just `/build`. The full chain is for genuinely uncertain or high-blast-radius work — never for a typo. ## commands **the loop** — run these every time: | cmd | job | |---|---| | `/ck:spec` | create / amend / backprop `SPEC.md`. Sole mutator. | | `/ck:build` | native plan → execute against spec. Names which test proves each `§V`. Auto-backprops on failure. | | `/ck:check` | read-only drift report. Lists §V / §I / §T violations. The drift detector. | **reach for these** — only when the change earns the ceremony: | cmd | job | |---|---| | `/ck:grill` | interrogate a fuzzy idea into a sharp `§G`/`§C`, one question at a time, before you spec. | | `/ck:research` | gather external knowledge into `§R` so build grounds in facts, not hallucinations. Every finding cites a source. | | `/ck:review` | adversarial senior review of the spec *before* build. Refutes, hardens `§V`, ends in a go/no-go gate. | | `/ck:deepen` | spare-budget design pass — make one shallow module deep. Behavior held, tests green before & after. | ## install One line, via the `skills` CLI: ```bash npx skills add JuliusBrussee/cavekit ``` Installs nine skills into `~/.claude/skills/`: `spec`, `build`, `check` (the loop), `grill`, `research`, `review`, `deepen` (reach-for), plus `caveman` and `backprop` (the utilities). Claude activates each when its trigger context matches — e.g. "write a spec for…" invokes `spec`, a fuzzy idea invokes `grill`, a risky change before build invokes `review`. Claude Code picks them up on next launch. Or via the Claude Code marketplace (also adds the `/ck:spec`, `/ck:build`, `/ck:check`, `/ck:grill`, `/ck:research`, `/ck:review`, `/ck:deepen` slash commands): ```bash /plugin marketplace add juliusbrussee/cavekit /plugin install ck@cavekit ``` Or clone directly: ```bash git clone https://github.com/juliusbrussee/cavekit.git ~/.claude/plugins/cavekit ``` ## format See [`FORMAT.md`](./FORMAT.md). Sections: §G goal, §C constraints, §I interfaces, §R research (optional, pipe table), §V invariants, §T tasks (pipe table), §B bugs (pipe table). Each verb owns specific sections — no verb rewrites a section it does not own. ## files ``` FORMAT.md spec schema + caveman encoding + sectioned ownership commands/ seven thin slash-command entry points → the skills (loop + reach-for) skills/spec spec mutator — sole writer skills/build plan-execute, verification contract skills/check drift report skills/grill sharpen a fuzzy idea → §G/§C before spec skills/research external knowledge → §R, every finding sourced skills/review adversarial senior review of the spec → hardens §V skills/deepen spare-budget design pass — make one module deep skills/caveman encoding utility skills/backprop bug → spec protocol (six steps) ``` ## non-goals - no sub-agents. Main Claude does the work. - no dashboards. `cat SPEC.md` is the dashboard. - no parallel workers. One thread, one spec, one diff. - no JSON / YAML spec bodies. Markdown + pipe tables. - no hooks, no orchestration binaries, no TypeScript helpers. --- ## older cavekit (the Hunt lifecycle, v3.1.0 and earlier) The previous generation is **not deprecated** — it is frozen at tag [`v3.1.0`](https://github.com/juliusbrussee/cavekit/tree/v3.1.0) and remains a fully working plugin. **What it is**: > Spec-driven AI development with an autonomous execution loop. Four-command > Hunt lifecycle (`/ck:sketch` → `/ck:map` → `/ck:make` → `/ck:check`), > plus `/ck:ship`, `/ck:review`, `/ck:revise`, `/ck:status`, `/ck:design`, > `/ck:research`, `/ck:init`, `/ck:config`, `/ck:resume`, `/ck:help` — 16 > slash commands total. 12 named sub-agents. Per-task token budgets, > stop-hook state machine, model-tier routing, auto-backpropagation from > test failures, tool-result caching, Codex peer review, Karpathy > behavioral guardrails, caveman token compression, knowledge-graph > integration, and design-system enforcement. Parallel wave execution and > team mode. **Pick v3.1.0** if you want the full autonomous loop, parallel agents, peer review, or design-system workflow. **Pick v4** if you want the distilled loop — one spec, no orchestration, right-sized ceremony. ### install the older version Marketplace: ```bash /plugin marketplace add juliusbrussee/cavekit@v3.1.0 /plugin install ck@cavekit ``` Git: ```bash git clone -b v3.1.0 https://github.com/juliusbrussee/cavekit.git ``` Full docs live at the tag — `git checkout v3.1.0` and read the README there for command reference, skill catalog, and the Hunt lifecycle guide. ### choosing, or moving See [`UPGRADE.md`](./UPGRADE.md). Honest framing: - Stay on v3.1.0 if your project has active `context/kits/` investment. - Move to v4 if you want fewer moving parts and smaller token bills. - It is a **two-way door** — `SPEC.md` is plain markdown; nothing traps you in either direction. ## ecosystem Cavekit is one rock in the caveman family: | repo | what | status | |---|---|---| | [caveman](https://github.com/JuliusBrussee/caveman) | output compression skill + engine — *why use many token when few do trick* | live | | [caveman-browse](https://github.com/JuliusBrussee/caveman-browse) | token-efficient browser automation | live | | [cavegemma](https://github.com/JuliusBrussee/cavegemma) | Gemma 4 31B fine-tuned on caveman pairs — *why prompt every turn when weight remember* | labs | | [cavemem](https://github.com/JuliusBrussee/cavemem) | cross-agent persistent memory — *why agent forget when agent can remember* | frozen | | **cavekit** *(you here)* | spec-driven build loop — *why agent guess when agent can know* | frozen | ## philosophy > The spec is the only artifact that earns its tokens. Everything else > that costs tokens must either save more tokens later, or the user's > attention, or it gets cut. See [`CHANGELOG.md`](./CHANGELOG.md) for the full v3 → v4 break. ## license MIT.
