MisakaNet

A redacted failure-memory layer for AI coding agents.

Paste an error from Cursor, Claude Code, Codex, or CI. MisakaNet searches real failure-recovery lessons and returns a fix path.

mcp-name: io.github.Ikalus1988/misakanet

What is this?

MisakaNet is a failure-memory layer for AI coding agents. When your agent hits an error — DCO failure, pip timeout, GitHub 401, MCP setup issue — MisakaNet searches 271+ indexed failure-recovery lessons and returns a fix path. No prompt leaking, no raw logs stored.

When to use it

• Cursor / Claude Code / Codex hits an error you haven't seen before
• CI fails and you don't know why
• DCO, token, pip, MCP, encoding issues repeat across projects

Try it in 30 seconds

Option A: Remote MCP (Recommended — no clone needed)

1. Open https://misakanet.org/connect in your browser
2. Click "Generate Code" — get a 6-character pairing code
3. Add to your MCP config:

{
  "mcpServers": {
    "misakanet": {
      "url": "https://misakanet.org/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN"
      }
    }
  }
}

Then ask: "Search MisakaNet for database locked"

Option B: Local MCP (Cursor / Claude Desktop / Claude Code)

{
  "mcpServers": {
    "misakanet": {
      "command": "python3",
      "args": ["scripts/mcp_server.py"]
    }
  }
}

Option C: CLI

pip install misakanet-core
python3 search_knowledge.py "GitHub token 401"

Option D: Docker (no local Python needed)

docker pull ghcr.io/ikalus1988/misakanet:latest
docker run -i ghcr.io/ikalus1988/misakanet:latest search_knowledge.py "database locked"

Use cases: CI smoke test, isolated trial, Claude Desktop MCP config with Docker.

Option E: Web

How it works

1. Agent hits an error (DCO, pip, token, MCP, encoding, CI)
        ↓
2. Search MisakaNet for matching failure-recovery lessons
        ↓
3. Read the matching lesson
        ↓
4. Apply the documented fix
        ↓
5. If no lesson matches, opt in to capture a redacted failure report
        ↓
6. Maintainers review accepted contributions and convert them into draft lessons

🧱 Product Matrix — The Full Stack

The MisakaNet ecosystem is built as a layered defense & knowledge stack:

└──────────────────────────────────────────────────────────────────┘

How the layers connect

1. fatal-guard wraps any Node.js process → crash captures a 4-field tombstone
2. Tombstone → scripts/tombstone_to_draft.py → lessons/drafts/ (auto-PR)
3. Draft lessons feed into bench-core as dynamic "unsolved mystery" tasks
4. Agents solve drafts → verified lessons enter the MisakaNet knowledge base
5. All ranking is powered by misakanet-core (zero-dep BM25 + RRF)

This is the 路线A→C 闭环: Crash → Draft → Benchmark → Verified Lesson → Searchable Knowledge.

# Any third-party tool can reuse the core engine:
from misakanet_core import BM25, tokenize, rrf

# Or wrap any CLI with crash protection:
# $ npx @misaka-net/fatal-guard -- node app.js

What is the Swarm Knowledge Protocol?

A shared experience substrate for AI agents. One agent stalls on a failure → documents the workaround → all agents skip that same failure path. No server. No database. No daemon. Just git clone + python3 search_knowledge.py.

In practice, MisakaNet is most valuable as a recovery layer during task execution, not as a separate reading experience. The primary direct user is usually an agent, not a human. Agents reuse known fixes so future tasks stall less on previously-solved failures. Human users often benefit indirectly: fewer stuck tasks, fewer repeated recovery steps, less manual intervention.

• Lesson — a piece of knowledge. Markdown file with problem → root cause → fix → verify.
• Node — an AI agent or developer who contributes and searches lessons.
• Search — BM25 keyword retrieval across all lessons. Zero dependencies. Python stdlib only.

Why?

AI agents hit the same bugs across different environments. Each one independently debugs pip on WSL, ChromaDB on NTFS, or FANUC error codes. The fix exists in someone's terminal history, invisible to everyone else. MisakaNet turns individual debugging sessions into shared, searchable knowledge.

Lesson vs Skill

MisakaNet lessons are not skills.

One line: Skill teaches an agent how to do something. Lesson teaches an agent what went wrong before and how not to fail again.

MisakaNet is not another skill marketplace. It is a shared failure-memory layer for developers and agents. Lessons come from real debug sessions, colleague-shared memory dumps, agent failure logs, and public contributor feedback.

Tools / MCP / Skills  →  do things
MisakaNet Lessons     →  avoid known failures
Benchmarks            →  measure reuse and robustness

Use skills when you want an agent to do something. Use MisakaNet when you want an agent or developer to avoid repeating known failures.

How is this different?

MisakaNet's moat: every new node and lesson makes the network exponentially more valuable — no server infrastructure required.

📦 Dependencies — layered architecture:

Layer	Dependencies	Install
Core engine — misakanet-core	Zero — pure Python stdlib	pip install misakanet-core
MisakaNet search — CLI + BM25 + RRF	Zero-dep — delegates to misakanet-core	git clone + python3 search_knowledge.py
Advanced search — --semantic	sentence-transformers (~2GB model)	pip install misakanet[semantic]
Hub mode — federation	aiohttp, websockets	pip install misakanet[hub]
Feishu integration	requests	pip install misakanet[feishu]

Only ever install what your node needs. Core search works in air-gapped sandboxes.

Capability stability tiers:

Tier	Components	Confidence
Stable	Core search (search_knowledge.py), BM25 + RRF via misakanet-core, lesson retrieval, contribution path, schema validation, fatal-guard wrapper	🟢 Production-ready
Beta	Agent integration patterns, telemetry pipeline, quality scoring, bench-core orchestrator, draft lesson pipeline, proof-of-access quotas	🟡 Well-tested, feedback welcome
Experimental	Hub federation, master mode, advanced worker/registration flows, --semantic multi-modal search	🟠 Evolving — expect breakage

Only the stable layer carries a strong backwards-compatibility commitment.

LessonReuseBench — Can agents learn from failures?

MisakaNet includes a benchmark that tests whether AI agents reuse prior lessons instead of re-debugging from scratch:

python3 scripts/lesson_reuse_bench.py --dry-run

Traditional benchmarks test: Can the agent fix this bug? LessonReuseBench tests: Can the agent fix this bug using prior experience?

Use in Cursor / Claude Desktop / Claude Code

Give your AI assistant access to failure-recovery lessons via MCP:

Remote MCP (Recommended):

{
  "mcpServers": {
    "misakanet": {
      "url": "https://misakanet.org/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN"
      }
    }
  }
}

Local MCP (Alternative):

{
  "mcpServers": {
    "misakanet": {
      "command": "python3",
      "args": ["/path/to/MisakaNet/scripts/mcp_server.py"]
    }
  }
}

Then ask: "Search MisakaNet for database locked" → Full MCP quickstart →

Copy this to your coding agent

Paste this into Cursor, Claude Code, or Claude Desktop to install and test MisakaNet in one shot:

Please install and test MisakaNet as an MCP failure-memory server.

Option A: Remote MCP (no clone needed)
1. Open https://misakanet.org/connect in your browser
2. Click "Generate Code" — get a 6-character pairing code
3. Tell me the pairing code and I'll configure the MCP connection

Option B: Local MCP
1. Clone https://github.com/Ikalus1988/MisakaNet
2. Configure it as an MCP stdio server:
   - Command: python3
   - Args: /path/to/MisakaNet/scripts/mcp_server.py
3. Restart your MCP client (Cursor / Claude Code / Claude Desktop)
4. Run the first query: Search MisakaNet for "database locked"
5. Confirm that misakanet_search returns failure-recovery lessons with title, score, and path.

MisakaNet is a failure-memory and recovery layer for coding agents / MCP clients. → Full MCP quickstart →

MCP status: MisakaNet is already registered as an MCP server on Glama, and local stdio MCP calls are verified. Glama Tool Calls = 0 means 0 Glama-routed tool calls; it does not mean MCP is broken or that local usage is zero. See the analytics counting boundary.
