KeiSeiKit

A multi-LLM substrate that gives any agentic coding tool persistent memory, deterministic agent identity, and self-maintaining orchestration. Works first-class with Claude Code; MCP-compatible bridges generate context for Cursor / Continue / Zed / Aider / Windsurf / Cline / OpenClaw / Kimi from the same source-of-truth.

Apache 2.0 — explicit patent grant + retaliation clause. 102 Rust crates (~132K LOC), 67 skills, 35 hooks, 37 agent manifests, 82 substrate blocks, 18 capability bundles, 7 substrate roles. Self- indexing via kei-registry SQLite (currently 495 active DNAs across the public substrate). Three-phase nightly consolidation. Foreign-project ingestion runtime (kei-import <repo-url>).

Maturity matrix

The substrate ships as a layered set of components at different maturity levels. Read this before relying on any single piece for production work.

Component	Status	Notes
24+ Rust primitives	varies (alpha → beta → concept)	Inspect each crate's Cargo.toml package.metadata.keisei.maturity if declared; otherwise treat as alpha unless you've personally exercised it. Most primitives are alpha — they build, type-check, and have unit tests, but have not been hardened against adversarial input or run at scale.
Cortex daemon (kei-cortex HTTP + WS)	alpha	CLI-driven daemon works in author's daily use; HTTP REST + WS endpoints + 8-tool /chat agentic loop build clean. Browser app (cortex-ui) and VSCode extension (@keisei/vscode-cortex) are concept-level — scaffolds present, not production paths.
MCP server (@keisei/mcp-server)	alpha (unpublished)	Not yet on npm. Install via local dist build (see Quick start below).
Sleep layer (Phase A / B / C)	alpha	Phase A queue (/sleep-on-it → cloud agent) + Phase B markdown morning report work. Auto-codification of rules from sleep insights is not yet wired — codification path is manual via /escalate-recurrence. Phase C deep-sleep refactor proposals run on a 7-day cadence and write plan-only markdown by default.
Hooks (35 shipped)	beta	Tested in author's daily use (4–8 parallel Claude Code terminals). Pipeline hooks (assemble-agents, no-hand-edit-agents) are load-bearing; advisory hooks (RULE 0.12 / 0.13 / 0.14) are non-blocking.
Skills + manifests + assembler	beta	Structured + assembler-validate gate runs on every git commit inside ~/.claude. Schema is locked (see docs/AGENT-SCHEMA-LOCKED.md).

What it does

Persistent memory	SQLite ledger + content-addressable memory store, session-spanning context, cross-machine sync via memory-repo
Agent DNA	Deterministic 80-char identity per invocation: <role>::<caps>::<scope-sha8>::<body-sha8>-<nonce>. Same task → same prefix → "did this run before?" via SQL, no embeddings
Constructor Pattern for prompts	Agent .md files composed from manifests + blocks + capability bundles + rule fragments. Edit a block → all agents using it recompose. Single source of truth
kei-fork	Atomic git triplet (branch + worktree + ledger row) for parallel agent runs. Atomic rollback. No main-branch collisions across 4-8 simultaneous Claude sessions
Three-phase sleep	Phase A incubation (queued tasks) → Phase B REM consolidation (analyzes last 30 sessions, writes morning markdown report) → Phase C NREM deep-sleep (every 7 days, conflict scan + refactor proposals). No feedback loop — outputs are markdown, you decide what to keep
Auto self-indexing	Every substrate file edit triggers registry update + agent regeneration + DNA-INDEX.md refresh + keimd graph reindex
Foreign-project ingestion	kei-import <repo> walks → matches against 12 runtime traits → extracts skills from README/docs → generates migration plan → produces per-phase agent prompts
Cross-tool bridges	One rule-set, 11 target formats (.cursorrules, .windsurf/rules/main.md, .github/copilot-instructions.md, AGENTS.md, GEMINI.md, etc)
npm-style publishing path	Publish your agents / skills / hooks as scoped packages. The author runs an opt-in mirror at keigit.com (public Forgejo + npm registry, OAuth, per-user PAT) — this is an author-operated mirror (KeiSei84 / private Forgejo), not a neutral community service. The substrate is remote-agnostic; use any git remote and any npm registry you trust. See docs/PUBLISHING.md

Why it exists

The author runs 4-8 parallel Claude Code terminals daily. Without substrate, every session loses context, every parallel agent collides on main, every "did we already solve this?" requires manual grep. With substrate, identity carries — agents know what ran before, results converge through the ledger, fork-as-triplet prevents collisions, three-phase sleep produces overnight consolidation.

This is a tool first, not a product. If it solves your problem, fork it.

Quick start

# Claude Code (primary target — full hook + agent integration)
/plugin marketplace add KeiSei84/KeiSeiKit
/plugin install keisei@keisei-marketplace

# Any MCP-compatible client (Cursor / Continue / Zed / Aider / etc)
git clone https://github.com/KeiSei84/KeiSeiKit-1.0
cd KeiSeiKit-1.0
./install.sh --profile=minimal

37 agents + 67 skills + 35 hooks + nightly consolidation wired in 60 seconds. Eleven install profiles (minimal → core → full + MCP-only / Cortex / Cursor / Continue / Zed / Aider / Docker / Nix) documented in docs/INSTALL.md.

Outcome-only — try just the outcome loop (5 files, ~200 LOC)

If you want to try only the outcome-tracking primitive without committing to the full kit (no daemon, no Forgejo, no launchd, no 100 crates), run ./install.sh --profile=outcome-only. Installs 2 hooks + a SQLite ledger + one line in ~/.claude/CLAUDE.md; uninstalls in four lines. See docs/PROFILE-OUTCOME-ONLY.md.

Self-maintaining

After install, the substrate maintains itself. Every edit cascades:

edit any rule .md       → kei-decompose registers fragments
edit any manifest .toml → assembler regenerates one agent .md
edit any block .md      → assembler regenerates ALL agents
edit any skill SKILL.md → kei-registry updates
edit any hook .sh       → kei-registry updates
edit any primitive src/ → kei-import-project register updates
ANY substrate edit      → DNA-INDEX.md auto-refreshes
ANY substrate edit      → keimd graph auto-reindexes

nightly:
  Phase A (incubation)         → process queued tasks
  Phase B (REM consolidation)  → analyze last 30 sessions → morning report
  Phase C (NREM, every 7d)     → conflict scan + refactor proposals

No automatic feedback loop into agent state. All consolidation outputs are human-readable markdown. You read, you decide what merges.

Honest limits

• Phase 5 executor (kei-import-project) generates per-phase agent prompts as JSON; the actual Agent({...}) spawn happens orchestrator-side (Claude Code Agent tool, MCP wrapper, or a thin shell loop). A first-class JS/TS wrapper that auto-spawns + tracks is future work.
• Phase 9 Path A (model-router assembler-time rebake) — 37 agent manifests currently declare model: opus in frontmatter. Bayesian posterior router activates per-task-class when ≥100 outcome rows accumulate (currently 3). Until then, routing happens via orchestrator discipline plus advisor-hook stderr nudges.
• Cortex stack (kei-cortex / kei-tty / kei-mcp) ships as alpha (CLI/daemon track) — downgraded from "beta" because two of the three intended frontends are not yet shipping. Local HTTP daemon + ratatui TUI + MCP stdio JSON-RPC build clean and run in the author's daily use. Browser app (cortex-ui) and VSCode extension (@keisei/vscode-cortex) are concept-level only — scaffolds exist, no production wiring. Treat the daemon + CLI as the supported surface; treat the GUI frontends as roadmap.
• @keisei/mcp-server npm package — not yet published to npm. Install via the local dist build:

  cd _ts_packages
  bun install            # or: npm install
  bun run -r build       # or: npm run -r build
  # mcp-server output lands in _ts_packages/packages/mcp-server/dist/
  

  Then point your MCP-aware client at the local dist/ entry point. Single-binary builds via bun build --compile are documented in _ts_packages/packages/mcp-server/BUILD.md (5-target matrix, ~85–95 MB per binary). Do not assume npm-registry install will work until v1.0.
• Non-Claude clients integrate via MCP + bridges, not native hooks. PreToolUse / PostToolUse / UserPromptSubmit / Stop semantics are Claude Code primitives. Other clients get capability exposure but not the hook wire-up.

What it's NOT

• Not a Claude Code replacement — runs alongside, not instead-of
• Not a SaaS — local-first by default; hosted offering under consideration if community demand emerges (see Roadmap)
• Not enterprise — solo-maintained, no SLA, no dedicated support
• Not a framework — substrate. You compose; it doesn't dictate workflow

Roadmap

The substrate is functionally complete for solo-developer use. What might be valuable as a hosted service if there's demand:

• Cross-machine memory sync — DNA-indexed memory available across laptop + desktop + cloud Claude session
• Hosted Phase B/C nightly — traces consolidated by a remote agent, morning report delivered to inbox
• Encyclopedia search-as-API — query team substrate by DNA / role / capability across multiple agents

These are considered, not committed. Open an issue with your use-case if any of these would solve real pain. Until then: fork, run locally, file PRs.

Hermes — proof of foreign-architecture ingest

Ten phases of Nous Research's Hermes (MIT, Python agent framework) ingested into KeiSeiKit substrate through April 2026. Each Hermes concept lives as a KeiSeiKit primitive:

Hermes phase	KeiSeiKit landing
ShareGPT trajectory export	kei-export-trajectories crate
OpenAI-compat HTTP server	kei-llm-router providers + chat handler
Daytona sandbox backend	kei-backend-daytona (with toolbox proxy URL split)
Injection-guard on memory writes	wired through kei-memory::ingest + kei-pet::memory
Memory-nudge invoker	Invoker trait + MemoryStore Arc plumbed
SKILL.md skill format	kei-skills::SkillRegistry, consumed by kei-mcp
Skill-invocation aggregation	kei-ledger schema v8 + aggregate-skills CLI
Multi-platform gateway	kei-gateway (Telegram / Discord / Slack / CLI)
Cron / scheduler	kei-cron-scheduler parser+job+runner

The kei-import umbrella runs the same pipeline (decompose → match → extract-skills → plan → execute) on any Rust / TS / Python / Go repo. Hermes was the validation case; the runtime works on others.

Frontend design — anti-AI-slop philosophy

The frontend-design skill is a deliberate counter-position to the same-shape output of v0 / Lovable / Bolt:

• 10 archetypes — Editorial / Swiss / Brutalist / Minimal / Maximalist / Retro-Futuristic / Organic / Industrial / Art Deco / Lo-Fi. Each declares typography pairing + color palette + layout language + motion style.
• OKLCH color system — one --brand-hue controls the full palette, perceptually uniform.
• Phase Gate (mandatory before any code): purpose, archetype, the one differentiator, three anti-references, design tokens. Skip the gate = skip the skill.
• Hard bans: Inter / Roboto / Space Grotesk, purple gradients on white, centered card grids as default, hero → cards → testimonials template, linear easing on UI transitions.
• Diverge-Kill-Mutate loop when output feels generic.
• The Blur Test: at 20% visibility, layout silhouette must be distinguishable from anti-references.

Orchestrator skill landing-page composes 11 skills across 6 recipes (apple-product / saas / portfolio / ecommerce / agency / startup).
