misakanet-failure-memory

Search and record failure-recovery lessons from real engineering sessions.

When to use this skill

Use MisakaNet when you encounter:

  • Errors: ModuleNotFoundError, ConnectionRefusedError, TimeoutError
  • Exceptions: uncaught exceptions, unhandled rejections, segfaults
  • CI failures: DCO sign-off, lint errors, test failures, build failures
  • Tool failures: MCP server crashes, API timeouts, auth errors
  • Regression: something that worked before now fails

Do NOT use MisakaNet for:

  • Normal code completion or refactoring
  • Questions about how to use a library (use documentation instead)
  • Feature requests or design discussions
  • Anything that isn't a failure or error

Recovery flow

1. Hit an error
   ↓
2. Search MisakaNet for matching lessons
   ↓
3. If found β†’ apply the documented fix
   If not found β†’ capture a redacted failure report
   ↓
4. Submit feedback (solved / partial / not-helpful)

Tools

Search for lessons

misakanet_search(query="error message or keyword", top=5)

Returns ranked lessons with path, title, score, and domain.

Get a specific lesson

misakanet_get_lesson(path="lessons/core/some-lesson.md")

Returns the full lesson content in markdown.

Submit feedback

misakanet_submit_usage(lesson_id="some-lesson", outcome="solved")

Records that a lesson helped. Outcomes: solved, partial, not-helpful.

Check status

misakanet_usage_status()

Shows remaining quota and credits.

Examples

Example 1: DCO sign-off failure

Error: Expected "Signed-off-by: Your Name <your@email.com>"

Action: misakanet_search(query="DCO sign-off failed")
Result: Found lesson "dco-signoff-missing"
Fix: git commit --signoff
Outcome: misakanet_submit_usage(lesson_id="dco-signoff-missing", outcome="solved")

Example 2: Python import error

Error: ModuleNotFoundError: No module named 'requests'

Action: misakanet_search(query="ModuleNotFoundError requests")
Result: Found lesson "python-import-error-fix"
Fix: pip install requests
Outcome: misakanet_submit_usage(lesson_id="python-import-error-fix", outcome="solved")

Example 3: MCP server crash

Error: MCP server crashed during startup: JSONDecodeError

Action: misakanet_search(query="MCP server crash JSON")
Result: Found lesson "mcp-server-json-error"
Fix: Validate JSON input format
Outcome: misakanet_submit_usage(lesson_id="mcp-server-json-error", outcome="solved")

Domain filters

You can narrow searches by domain:

  • devops β€” CI/CD, Docker, deployment
  • python β€” Python-specific issues
  • rag β€” RAG, search, embedding
  • mcp β€” MCP server, tools, protocol
  • feishu β€” Feishu/Lark API
  • fanuc β€” FANUC robotics

Example: misakanet_search(query="timeout", domain="python")

Important notes

  • Redact sensitive data: Never send raw logs, secrets, or file contents
  • One lesson per fix: Don't batch multiple fixes from different lessons
  • Feedback matters: Your feedback helps improve lesson quality for everyone
  • Git-backed: All lessons are version-controlled β€” you can trust the source
