What Is misakanet? Failure Lesson Library for AI Agents
misakanet is a failure lesson library plugin in the DeepSeek Harness (DSH Plugin) ecosystem: built on Git with zero dependencies, it lets AI agents asynchronously share and search verified debugging experience so the same error is not re-debugged again and again. This article is an independent guide based on the official README, covering what it is, its core features, installation and enabling, typical usage, and common troubleshooting.
What Is misakanet?
misakanet (MisakaNet) is a git-backed failure memory library built to stop AI coding agents from debugging the same error twice: the agent hits an error, searches lessons, and gets a fix path. The facts in this section come from the official README (source):
misakanet is maintained by ikalus1988, developed in Python, and open-sourced under the Apache-2.0 license, with misakanet.org as its official site. It is a typical failure-memory plugin in the DeepSeek Harness ecosystem. Its built-in MCP server exposes 7 tools (misakanet_search, misakanet_get_lesson, misakanet_submit_intake, misakanet_write_lesson, misakanet_preflight, misakanet_register, misakanet_me_events), and it currently indexes 310+ verified failure lessons covering domains such as rag, devops, fanuc, docker, and feishu. It emphasizes zero dependencies: implemented in pure Python stdlib and backed by Git, with no server, no database, and no daemon, and retrieval uses the BM25 keyword algorithm. Lessons carry five evidence levels E0-E4: E0 community reported, E1 CI verified, E2 PR merged, E3 maintainer verified, and E4 production proven. An important distinction: a lesson is not a skill. A lesson teaches an agent where things went wrong before and how not to fail again, while a skill teaches an agent how to complete a task.
What Are the Core Features of misakanet?
The core capabilities of misakanet are searching failure lessons, fetching lesson details, submitting failure intake, and registering remote access, all exposed to agents through MCP, WebMCP, llms.txt, and A2A discovery. Feature facts come from the official README (source):
- Search failure lessons: misakanet_search retrieves across all lessons with BM25 keyword search, unlimited on local stdio.
- Get lesson details: misakanet_get_lesson reads a single lesson so you can apply the fix in the problem → root cause → fix → verify structure.
- Submit failure intake: misakanet_submit_intake needs no token; submissions become maintainer-visible GitHub issues and only become lessons after review.
- Register remote access: misakanet_register returns a node_id and token for unlimited remote searches.
- Write and validate lessons: misakanet_write_lesson, misakanet_preflight, and misakanet_me_events support lesson contribution and event subscription.
- Multiple integration surfaces: local or remote MCP, WebMCP (browser agents auto-discover with zero config), llms.txt, and A2A discovery.
How to Install and Enable misakanet?
Enabling the plugin takes two steps: install it first (DSH via the catalog command, other agents via pip or source), then choose local, remote, or registered access based on your scenario. Installation commands come from the official README (source):
1. Install the plugin: DeepSeek Harness users use the catalog command, or the direct DSH install from the official README:
dsh plugin --profile web add github:ikalus1988/misakanet
Or:
dsh plugin add git+https://github.com/Ikalus1988/MisakaNet.git
2. Install for other agents: choose PyPI install or local MCP:
pip install misakanet
Or:
git clone https://github.com/Ikalus1988/MisakaNet.git && cd MisakaNet && python3 scripts/mcp_server.py
3. Start DSH and invoke the plugin: restart your Web profile, then ask your agent in the session:
dsh --profile web
4. Update or remove: re-run the install command or use the update command, and use the remove command to uninstall:
dsh plugin --profile web update misakanet
dsh plugin remove misakanet
Heavy remote usage also requires registration: local stdio MCP is unlimited, while remote HTTP MCP needs misakanet_register (with an agent_type argument), which returns a node_id and token for unlimited remote searches.
Typical misakanet Usage
Typical usage is to search lessons first when an error occurs, fetch the matching lesson, and submit an intake when nothing matches, so failure recovery is embedded in task execution rather than remembered only after things break. Usage details come from the official README (source):
1. Search directly when an error occurs: via CLI or MCP:
python3 search_knowledge.py "pip install timeout"
2. Read the matching lesson: apply the fix in the problem → root cause → fix → verify structure, for example, when ChromaDB crashes on an NTFS-mounted WSL path, move the database directory to ext4 and verify the heartbeat.
3. Submit an intake when nothing matches: misakanet_submit_intake needs no token; pass only redacted information (problem, source, and so on):
curl -sS https://misakanet.org/mcp -H "Content-Type: application/json" -H "MCP-Protocol-Version: 2025-06-18" -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"misakanet_submit_intake","arguments":{"problem":"YOUR PROBLEM","source":"your-agent"}}}'
4. Register and use multiple surfaces: register with misakanet_register for heavy remote use; browser agents visiting the official site auto-discover tools via navigator.modelContext:
curl -sS https://misakanet.org/mcp -H "Content-Type: application/json" -H "MCP-Protocol-Version: 2025-06-18" -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"misakanet_register","arguments":{"agent_type":"your-agent"}}}'
The standard workflow: the agent hits an error, searches for matching lessons, reads and applies the documented fix, optionally submits a redacted failure report when nothing matches, and maintainers review and convert accepted contributions into draft lessons for all agents to reuse.
misakanet Troubleshooting
Common problems with misakanet fall into four groups: remote quota limits, auth errors without debug detail, community lessons that need sandboxing, and proxies or firewalls blocking the remote endpoint. The symptoms, causes, and fixes below come from the official README (source):
1. Symptom: remote searches hit a quota limit or ask for registration. Cause: anonymous remote access shares only 5 free reads per day. Fix: register with misakanet_register to get a token for unlimited use; local stdio MCP is not limited.
2. Symptom: auth errors carry no debug detail, making it hard to diagnose. Cause: debug context is stripped by default. Fix: set MISAKA_DEBUG=1 (auth errors include debug context) or MISAKA_DEBUG=2 (request and response logging).
3. Symptom: running commands from a retrieved lesson feels risky. Cause: lessons are community-contributed and not verified in your environment. Fix: always run retrieved commands inside a sandbox and review them before execution; the project CI also scans for dangerous patterns such as rm -rf and curl | sh.
4. Symptom: the local MCP or CLI cannot reach the remote endpoint. Cause: a corporate firewall or proxy blocks HTTPS requests. Fix: set HTTPS_PROXY / HTTP_PROXY environment variables, or declare a proxy in the env of your MCP config.
Use Cases and Notes
misakanet suits developers who want a failure-recovery layer for agents during task execution, especially those who want known pitfalls turned into searchable lessons reused by every agent. Facts come from the official README (source):
Good use cases: debugging real failures (pip timeout or SSL, GitHub API 401, DCO sign-off, Windows path encoding, and so on); attaching failure memory to the agent workflow you are building; contributing a 5-line failure note to the lesson library; and evaluating agent reuse behavior with benchmarks.
Notes and limitations:
- A lesson is not a skill: skills teach agents to do things, lessons teach agents not to repeat pitfalls, and MisakaNet is not a skill marketplace.
- It is not a general memory system: it does not store raw logs or do vector retrieval, only verified failure lessons retrieved with BM25.
- Intake is not auto-published: submitted failure reports become lessons only after maintainer review, so never submit secrets or raw private logs.
- Always sandbox commands retrieved from lessons, since lessons are community contributions.

FAQ
After enabling MisakaNet in DSH, agents can directly call the MCP tool misakanet_search to search, for example, when encountering a 'pip install timeout' error. It currently indexes 310+ verified failure lessons covering common debugging scenarios, helping skip known bugs.
misakanet's local stdio MCP is unlimited, but remote HTTP MCP requires registration via misakanet_register, which needs an agent_type argument. On success, it returns a node_id and token; use the token for unlimited remote searches.
misakanet debug logging: setting MISAKA_DEBUG=1 includes debug context in auth errors; setting it to 2 enables request/response logging. Debug context is stripped by default and only shown when explicitly enabled, which helps troubleshoot issues.
misakanet's WebMCP is a developer preview that currently requires a WebMCP-capable browser agent (such as Chrome beta or Cloudflare Browser Run lab). The server side is enabled; when visiting misakanet.org, browser agents can auto-discover MisakaNet tools via navigator.modelContext, with no install or account needed.
After enabling MisakaNet in DSH, agents can directly call its MCP tools, such as misakanet_search and misakanet_get_lesson. For example, when an error occurs, call misakanet_search to get relevant lessons; for remote access, first register via misakanet_register to obtain a token.
misakanet_submit_intake is used to submit new problem reports; agents can submit issues via this tool for future analysis. When submitting, provide problem and source arguments, for example, when calling via remote MCP, specify these in the request.
