Runtime Failure-Memory Smoke Test Matrix

Date: 2026-08-03 Version: v2.14.0 Related issue: #757

Entry points

MisakaNet provides four runtime entry points for failure-memory suggestions:

Entry point File Trigger
Cursor rule .cursor/rules/misakanet-failure-memory.mdc IDE auto-detects terminal failures
Claude Code playbook docs/integrations/claude-code-failure-memory.md Manual or prompted failure analysis
misaka run wrapper scripts/misaka_run.py CLI: wrap any command
Shell helper scripts/misaka-search.sh CLI: misaka-search "query" or mk "query"

1. Cursor Rule

Setup

  1. Confirm .cursor/rules/misakanet-failure-memory.mdc exists in your project root (already present in this repo).
  2. Open the project in Cursor IDE.
  3. The rule activates automatically — no manual config needed.

Trigger

Run a failing command in Cursor's integrated terminal:

npm run nonexistent-script
# or
python -c "import nonexistent_module"

Expected behavior

Cursor should detect the non-zero exit and surface the failure-memory rule. The rule instructs Cursor to search MisakaNet for matching failure-recovery lessons.

Limitations

  • Cursor IDE only (not VS Code, not JetBrains).
  • Rule must be in .cursor/rules/ — not .cursorrules (deprecated format).
  • Depends on Cursor's rule execution model, which may change.
  • First-time failures with no matching lessons will return empty.

2. Claude Code Playbook

Setup

  1. Review docs/integrations/claude-code-failure-memory.md.
  2. The playbook is a prompt/workflow document — it tells Claude Code how to invoke MisakaNet MCP tools on failure.

Trigger

After a failure in Claude Code's terminal, ask:

Check MisakaNet for this error.

Claude Code should call misakanet_search via MCP.

Expected behavior

Claude Code calls misakanet_search with the error text and returns matching lessons with titles, scores, and paths.

Limitations

  • Requires Claude Code with MCP support configured.
  • MCP server must be running (python scripts/mcp_server.py).
  • Depends on Claude Code's willingness to call MCP tools.
  • Not fully automatic — user or playbook must trigger the search.

3. misaka run Wrapper

Setup

# No install needed — run directly from repo
python scripts/misaka_run.py --help

Trigger

python scripts/misaka_run.py npm test
python scripts/misaka_run.py python failing_script.py
python scripts/misaka_run.py --capture cargo build  # auto-submit intake on failure

Expected behavior

On non-zero exit: 1. Captures stdout/stderr from the failed command. 2. Searches MisakaNet lessons for matching failure patterns. 3. Displays top matches with title, score, and path.

Options: - --capture — auto-submit redacted failure report as intake (opt-in). - --top N — number of lessons to show (default: 3).

Limitations

  • Adds overhead (subprocess + search).
  • Interactive commands may behave differently when wrapped.
  • Search quality depends on error message clarity.
  • --capture sends data to /api/intake — only use if you understand the privacy model.

4. Shell Helper (misaka-search.sh)

Setup

source scripts/misaka-search.sh

This defines two functions: misaka-search and mk.

Trigger

misaka-search "database locked"
mk "pip install timeout"

Expected behavior

Calls search_knowledge.py with the query and displays matching lessons.

Limitations

  • Bash/Zsh only.
  • Must be sourced (not executed) — bash misaka-search.sh won't work.
  • Calls Python internally, so Python must be in PATH.
  • No color output on Windows CMD.

Smoke test checklist

Run each entry point and verify:

# Entry point Command Pass criteria
1 Cursor rule Open project in Cursor, run python -c "import nonexistent" Rule triggers, Cursor shows suggestion or search prompt
2 Claude Code After a failure, ask "check MisakaNet" MCP misakanet_search returns results
3 misaka run python scripts/misaka_run.py false Shows "Command failed" + lesson matches
4 Shell helper source scripts/misaka-search.sh && misaka-search "database locked" Returns lesson results
