Keyoku

Get Started

Install it once, then wire it up:

npm install -g keyoku
keyoku init

A global install keeps keyoku on a durable path. Running npx keyoku init from the throwaway npx cache is refused — npm can evict that directory and break the hooks — so install globally first.

The init command wires everything automatically:

1. Registers the MCP server — via claude mcp add --scope user, so Claude Code connects on next launch
2. Installs the hooks — activity recording (every Bash/Edit/Write/Read/MCP call), a session-start brief, and prompt-time practice injection
3. Wires Codex too — when ~/.codex exists, the MCP server lands in config.toml automatically (same tools, same workflows)
4. Stays local — no cloud, no telemetry; state lives in ~/.keyoku with the same file permissions as ~/.aws. keyoku pause stops everything instantly.

Restart Claude Code and keyoku is live. Then skip the cold start entirely:

keyoku import   # backfill months of history from your Claude Code transcripts

Now ask your agent to run workflow_suggest — keyoku mines your real history immediately instead of waiting days for new activity. Approved workflows appear as native slash commands (MCP prompts), and keyoku export <slug> bakes one into your repo as a Claude Code skill your whole team inherits.

How It Works

Without Keyoku: you describe the same multi-step process to your agent every session.

With Keyoku: you approve a workflow once, then run it with one command. The agent never has to rediscover it.

1. Activity tracing — automatic

Every tool call your agent makes is recorded as a lightweight ActivityEvent — tool name, summary, extracted entities. Purely local.

2. Pattern detection — heuristics for recall, a model for precision

workflow_suggest mines recurring sequences from your recent activity (non-overlapping counting, noise suppression, longest-chain collapsing — no model required). If an SLM key is configured (GEMINI_API_KEY or ANTHROPIC_API_KEY), the model then refines the drafts: filters coincidences, names workflows properly, and parameterizes run-specific values with {{placeholders}}.

2b. Muscle memory — converged goals become reusable workflows

A goal that converges (goal_assess reports all criteria met) promotes its action trace into a learned workflow. Next time you start a similar goal, keyoku surfaces what worked before — so the agent never rediscovers it.

• Capture happens three ways: explicit goal_record, live goal_focus (real actions stream into the goal's trace as you work), or activity backfill (if you just did the work without recording, keyoku lifts the steps from the activity log). Already have hollow workflows from older runs? keyoku backfill repopulates them.
• Reuse needs no API key. keyoku is driven by a frontier coding agent, so the agent is the judge of relevance. goal_assess returns candidateWorkflows and the agent picks the ones that genuinely apply — which matches verbose, differently-worded goals that token-overlap never could. A lite model is an optional accelerator for headless runs (keyoku watch/cron), not a requirement.
• It self-prunes. Suggestions rank by similarity × precision, where precision is learned from whether a workflow's steps actually recur — so word-matching-but-never-useful workflows sink.
• Negative memory too. Approaches that failed on the way to convergence are captured as pitfalls and surfaced as "avoid (failed before): …" on similar goals.
• Refine raw into clean. keyoku refine <slug> turns noisy captured steps into a tight, {{parameterized}} template ready to run.

3. Approval — you are the trust boundary

workflow_approve { slug: "deploy-staging", name: "Deploy staging", steps: [...] }

Review the draft like you'd review a shell script, then approve. Templates live in ~/.keyoku/templates.json.

4. Execution — bash runs, judgment pauses

workflow_execute { slug: "deploy-staging" }

• bash steps run directly (per-step cwd, timeouts, output captured)
• agent_prompt steps pause and hand the step to your coding agent, which resumes with execution_complete
• human_review steps wait for your explicit sign-off

Every execution persists step-by-step — crash-safe, fully inspectable via execution_list.

MCP Tools

Tool	What it does
activity_record / activity_list	Log and browse the observation stream
workflow_suggest	Mine patterns → model-refined draft workflows
workflow_capture	"Save what I just did" — last N session actions become a draft
workflow_approve / workflow_update	Save or edit templates (slash commands stay current)
workflow_template_list / workflow_template_delete	Manage the catalog
workflow_execute	Run a template (params fill {{placeholders}})
execution_complete / execution_cancel / execution_list	Resume, stop, browse runs
knowledge_submit / knowledge_query	The context layer — research, conventions, practice
goal_create / goal_assess / …	Goals with machine-checkable success criteria
goal_focus / goal_unfocus	Live capture — record real actions into a goal's trace as you work
connector_add / connector_call / …	Plug in external MCP servers (GitHub, GCP, …) with autonomy gating

keyoku import           Backfill activity from Claude Code + Codex transcripts (kills the cold start)
keyoku export <slug>    Bake a workflow into ./.claude/skills — or AGENTS.md with --agents-md
keyoku pause | resume   Privacy switch: stop/start all recording and injection
keyoku doctor           Verify hooks, MCP registrations, engine, and activity health
keyoku inspect          Show exactly what's stored in ~/.keyoku (--secrets scans for leaks)
keyoku status           Show goals, templates, connectors
keyoku learn            Mine patterns from the activity log
keyoku backfill         Repopulate hollow learned workflows from the activity log (--dry-run)
keyoku refine <slug>    Turn a workflow's raw steps into a clean, parameterized template (--apply)
keyoku focus <goal>     Live-capture actions into a goal's trace (--clear to stop; no arg to show)
keyoku assess <goal>    One-shot convergence check
keyoku watch <goal>     Re-assess on an interval
keyoku approvals        Approve/deny gated connector calls
keyoku audit [n]        Show the audit trail

The division of labor: heuristics generate candidates for free, the small model refines them cheaply, and your coding agent does the heavy lifting on the subscription you already pay for. Keyoku orchestrates; it never burns frontier tokens.

Security

Approved templates execute shell commands with your privileges — the approval step is the trust boundary. Read SECURITY.md before installing.
