Why kula

AI writes a growing share of the code, and the people shipping it trust it less every year. In the Stack Overflow 2025 Developer Survey, 84% of developers use or plan to use AI tools, 46% distrust their accuracy (33% trust it), and the most common complaint, at 66%, is code that is almost right, but not quite. The gap is context and control: an agent greps a codebase it cannot see the shape of, edits code it should never touch, and forgets what it learned between sessions. And the review that has to catch all of this still reads diffs line by line.

Developer tooling splits into camps, and each leaves part of that gap open:

Kula is the one place where those meet, because they all need the same thing: a graph of the code that stays current with git:

1. Workflows for agents. explore, fix, refactor, tests, docs and your own: each a work mode with its own fences, scope, steps, docs and memory policy. A refactor can't touch the tests that define "unchanged"; a test-writing session can't "fix" the code under test.

2. Fences that know the code. Lock a symbol, not just a path; hide secrets; scope a task to part of the graph. One verdict serves MCP, a pre-edit hook in Claude Code, Cursor, Codex and Gemini CLI, and the CI gate.

3. Memory anchored to code. What an agent learns is pinned to the function it describes, stored in git, and marked stale the moment that function changes.

4. Architectural review. graph-diff and Contrast show what a branch does to the structure: symbols gained, lost and rewritten, call edges added and cut, blast radius by risk.

5. Offline collaboration. Proposals, issues, notes and memories are git objects on refs/kula/meta: they work on a plane and sync through any remote.

6. A graph you can take with you. The whole graph is RDF under a published vocabulary: export Turtle or JSON-LD, or ask it anything in SPARQL.

Sixty seconds

cd your-repo
kula init                          # kula.toml · git hooks · agents connected · first graph
kula view                          # graph + git UI → http://localhost:7420
kula impact parseConfig            # what breaks if I change this?
kula graph-diff main WORKTREE      # what my uncommitted work does to the architecture
kula graph isolate src/auth/** --save auth   # one part of the code, who calls in, what it calls out
kula task start "split auth" -w refactor   # agents may restructure; tests are locked
kula commit -am "ship it"          # …and it's still just git

For AI agents

kula agents connect all     # Claude Code, Cursor, Codex, Gemini CLI: MCP server + pre-edit hook, in each one's own format
kula agents sync            # a brief of tools, fences and workflows in AGENTS.md, for every other agent

Enforced, not advised

Fences are not a paragraph in a prompt. Every way an agent can change code meets the same verdict:

Workflows

A workflow is a work mode. Start a task in one and its fences, scope, steps, docs and memory policy apply to every agent until the task is done.

kula workflow list
kula task start "split the auth module" --workflow refactor

[[workflow]]
name = "db-migrate"
about = "Schema changes, nothing else"
scope = ["migrations/**"]
lock = ["src/db/pool.rs"]
memory = "read"
steps = ["Write the migration and its rollback", "pre_edit every query on the changed tables", "verify_edit"]
docs = ["docs/MIGRATIONS.md"]

Any harness can work in any workflow: through MCP and the hooks, under kula run -w <name>, or as the agent's own file: kula workflow install <name> writes it as a Claude Code subagent (.claude/agents/), a Cursor rule (.cursor/rules/) and a Gemini CLI command (/kula:<name>).

Autoresearch

Give an agent a number to move (test time, bundle size, p95 latency, validation loss) and the code it may change. It forms a hypothesis, edits, and calls experiment: kula checks the change against the fences, runs the metric itself, commits the change when the number improves and reverts it when it doesn't. Agents never report their own scores, every kept step is a commit you can read, and memories carry what worked into the next run.

kula research init --metric "cargo bench --bench index 2>&1 | grep -o '[0-9.]* ms' | tail -1" --goal min --scope "src/index/**" --budget 40
kula research start                 # the baseline, on a research/ branch
kula research try "cache the parser per language"   # or the agent's `experiment` tool
kula research status                # baseline, best, every experiment

flowchart LR
    R[research<br/>baseline · best · what failed] --> H[one hypothesis]
    H --> E[edit, in scope<br/>fenced by the hook]
    E --> X[experiment<br/>kula runs the metric]
    X -->|better| K[kept as a commit]
    X -->|worse · failed · fenced| V[reverted]
    K --> M[remember why]
    V --> M
    M --> R

Teams

A team gives every agent its own workflow, and the hook holds each one to its own: Claude Code on an autoresearch loop, Cursor writing tests, Codex reviewing read-only – at the same time, in one checkout.

kula team save ship --lead claude -m claude=autoresearch:"speed up the indexer" -m cursor=tests -m codex=explore:review
kula team prompt ship codex     # the team's prompt, its own, its place, its workflow
kula team start ship

Teams carry a hierarchy (who leads, who answers to whom), hand-offs, and system prompts for the team and each agent; Agents › Teams draws them on the same renderer as the code graph, tinted by workflow. Start one from a template (ship a feature, bug hunt, research swarm, safe refactor, docs pass) and rewire it by dragging one member onto another.

Skills

One set of skills for every agent, kept in git. Each lives in .agents/skills/<name>/SKILL.md, which Codex reads directly; kula writes the same skill where Claude Code, Gemini CLI and Cursor look for theirs. A skill only one agent has can be adopted into the shared set.

kula skill new release-notes -d "Write release notes from the commits since the last tag"
kula skill list                 # each skill, and whether each agent has the current copy
kula skill adopt claude triage  # take an agent's own skill into the shared set
kula skill sync                 # write every skill where each agent reads it

When an agent's copy of a skill was edited locally, kula skill list shows it as differs; Agents › Skills shows the diff – the agent's copy against the source – before a sync overwrites it. The tab also shows which workflows and teams mention a skill, and the skill's own files.

Agent config: MCP and rules

TeamAI-CLI-style parity beyond skills: every agent's MCP servers (.mcp.json for Claude Code, .cursor/mcp.json for Cursor, .gemini/settings.json for Gemini CLI, .codex/config.toml for Codex) and rules files (CLAUDE.md, GEMINI.md, AGENTS.md, .cursor/rules/) are read where each one lies, and shown against the shared source in .agents/mcp.json. Syncing writes one server definition out to every agent and never clobbers the rest of their config.

kula agents mcp          # the matrix: MCP servers and rules per agent vs the source
kula agents mcp kula     # sync the kula server from .agents/mcp.json to every agent

Agent memories carry layers derived at read time, no new storage: each memory is labelled with its scope – task when its target is inside the active task's scope, else workflow when inside a workflow's scope, else repo – and its provenance: the agent that wrote it, the commit on refs/kula/meta that introduced it, and the symbol or file it is anchored to. Agents › Skills shows the table.

Fences

[[guard]]
paths = ["migrations/**"]
level = "locked"          # read, never edit
reason = "schema changes go through the DBA"

[[guard]]
symbols = ["src/billing.rs:charge_card"]
level = "review"          # editable; kula check lists it for a person

[[guard]]
paths = ["data/customers/**"]
level = "hidden"          # never shown to an agent, in any answer

flowchart LR
    T[kula.toml<br/>fences · workflows] --> V{{one verdict<br/>per path and symbol}}
    K[.kula/task.json<br/>task · scope · workflow] --> V
    S[secrets<br/>.env · keys · certs] --> V
    V --> M[MCP answers<br/>hidden code left out]
    V --> H[pre-tool hook<br/>edits, reads, shell, refused with the reason]
    V --> P[pre-commit hook<br/>an agent's fenced commit refused]
    V --> R[kula run<br/>any harness, held for the run]
    V --> E[verify_edit<br/>reports what slipped]
    V --> C[kula check<br/>fails the branch in CI]
    V --> U[UI<br/>fences on the graph]

The strongest level wins: hidden > locked > scope > review > open, so a task can narrow what kula.toml allows, never widen it. Likely secrets are hidden by default. Agents can suggest a fence or a workflow over MCP; only a person accepts it into kula.toml.

Memory

kula memory add login "tokens are hashed twice for legacy clients"
kula memory recall login       # its own, its file's, its callers' and callees', the repo's

stateDiagram-v2
    direction LR
    [*] --> fresh: remember, anchored to a hash of the code
    fresh --> stale: the code changes
    stale --> fresh: confirm, re-anchored
    fresh --> [*]: forget
    stale --> [*]: forget

A memory is one fact pinned to a symbol, a file or the repo, stored with the notes in git. Recall ranks by the graph, not by text similarity. When the code changes, the memory comes back stale instead of being trusted silently.

Tools

The full model (levels, the hook protocol per agent, recall ranking, the brief) is in docs/AGENTS.md.

The UI

kula view serves a local app at localhost:7420: loopback only, with a per-session token.

Getting around: ⌘K searches everything (# issues, @ branches, > commands); 1–9, 0, a, q switch views; ⌥← ⌥→ and the browser's back and forward walk through views and tabs; [ ] through inspected symbols; ? lists every shortcut. Every place has a shareable URL: #graph/<id>/impact, #graph/fences/refactor, #agents/memory, #issues/3.

Commands

Kula is a superset of git: anything it doesn't know goes straight to git, so kula rebase -i, kula bisect and kula lfs pull all work. Every graph command takes --json; -C <path> works like git's.

The full reference, kula.toml and CI are in docs/CLI.md.

The knowledge graph as RDF

kula kg export -f jsonld -o graph.jsonld        # ttl · nt · jsonld · rdfxml
kula kg sparql 'SELECT ?name (COUNT(?c) AS ?callers) WHERE {
  ?s a kula:Function ; kula:name ?name . ?c kula:calls ?s
} GROUP BY ?name ORDER BY DESC(?callers) LIMIT 10'

• Indexing. Files are walked in parallel (respecting .gitignore) and parsed with tree-sitter. 11 languages are built in – TypeScript/TSX, JavaScript/JSX, Python, Rust, Go, Java, C, C++, C#, Ruby and PHP, plus the script blocks of Vue, Svelte and Astro – and 173 more come as language packs via kula lang add (kula lang add --detected installs whatever the repository contains). A pack is the grammar as a native library, downloaded from this project's GitHub release and checked against its sha256 manifest, or compiled locally with --build; the binary stays at 28 MB. 130 packs extract definitions, calls and imports, 28 definitions and calls, 15 definitions only – measured on each grammar's own test corpus; the full table is in docs/LANGUAGES.md. Packs are 0.07–4.3 MB each on a measured sample of ten (173 packs ≈ 175–350 MB per platform, extrapolated from that sample); kula lang remove <id> deletes one. Packs are built for macOS and Linux (x86_64 and ARM); on Windows the 11 built-in languages are what you get for now. Calls resolve to the same file, then imported files, then a unique match in the same language family; a stoplist keeps .get() and .map() from wiring everything together. Clusters come from weighted label propagation.

• Any revision, without a checkout. A revision's graph is built from git objects (git ls-tree and one git cat-file --batch) and cached per commit. Symbols match across revisions by kind, path, container and name, and compare by a hash of their source.

• Storage. .kula/graph.db (SQLite and FTS5) is git-ignored, built beside the live file and swapped in with one rename, so a running kula view never reads a half-built graph. It reindexes in the background whenever HEAD moves.

• Cleans up after itself. Once kula view sits idle (15 min by default), it drops old kula run copies, temp files and cached graphs, and compacts the store. Change the timer in Settings → Disk or with kula clean --after 30 (0 turns it off); kula clean runs a pass now.

• Metadata in git. Issues, proposals, notes and memories are one JSON document committed onto refs/kula/meta: full history, nothing touches your branches, kula share publishes it (with the agent setup on refs/kula/setup) and kula sync pulls it; nothing is pushed until you share.

• Git itself is never reimplemented: kula shells out to git, so hooks, signing, credential helpers and LFS keep working.

• Security. The UI listens on 127.0.0.1, rejects foreign Host headers (DNS rebinding), requires a per-session token on every call, and validates revisions so they can't be read as options.

The internals (resolution, the store, risk, the meta ref, the API) are in docs/ARCHITECTURE.md.

Docs

Development

pnpm -C web install && pnpm -C web build   # UI → web/dist (embedded in release builds)
cargo run -- view                           # run against this repo
./scripts/test.sh                           # everything CI runs; --quick skips packaging
pnpm -C web test:ui                         # Playwright: desktop, tablet and phone, against this repo and a seeded fixture

Releasing: push a vX.Y.Z tag. release.yml builds five targets and publishes the GitHub release, .deb packages and the apt repository, PyPI wheels, npm packages, the crate and the Homebrew formula.

Roadmap

• Incremental re-indexing on file change (kula view --watch)

• Language packs for Windows

• Two-way sync with GitHub and GitLab issues and pull requests

• Time-travel: scrub through history and watch the architecture change

Contributing

Kula takes contributions through GitHub issues and pull requests.

• Bugs and ideas: open an issue. For a bug, include kula --version, your OS, what you ran and what happened; for a wrong graph edge or a fence that let a write through, a small repository or a one-line reproducer is ideal.

• Pull requests: for anything beyond a small fix, open an issue first so the approach can be agreed before you write it. Then fork, branch from main, and open a pull request that says what changed and how you checked it.

• Before you push: ./scripts/test.sh must pass (it is what CI runs), and UI changes should pass pnpm -C web test:ui. Keep commits focused, and add a test for any behaviour you change.

• New languages: most languages arrive as packs; see docs/LANGUAGES.md for how a pack is defined and built with scripts/build-langpacks.sh.
