Root cause analysis for bugs. Dispatches RCA executors in parallel, consolidates findings, and appends RCA Diagnosis to the plan file.

Same command for any agent — swap --agent for codex, cursor, copilot.

# RCA Stage Skill Diagnose a bug by dispatching root cause analysis executors. Consolidates findings and appends the RCA Diagnosis section to the plan file. --- ## Step 1: Load Config and Resolve Executors ```bash bun -e " import { loadDevBuddyConfig, getProviderType } from '${CLAUDE_PLUGIN_ROOT}/scripts/pipeline-config.ts'; const config = loadDevBuddyConfig(); const stage = config.stages['rca']; const executors = stage.executors.map(exec => ({ ...exec, providerType: getProviderType(exec.preset) })); console.log(JSON.stringify({ executors })); " ``` --- ## Step 2: Resolve Session Variables 1. Resolve tmpdir: ```bash bun -e "console.log(require('os').tmpdir())" ``` Store as `{TMPDIR}`. 2. Generate unique output IDs: ```bash bun -e "console.log(require('crypto').randomBytes(4).toString('hex'))" ``` Store as `{RAND}`. Output file for executor at index `{i}`: `{TMPDIR}/.vcp/oneshot/rca-{RAND}-{i}.json` 3. Ensure output directory: ```bash mkdir -p "{TMPDIR}/.vcp/oneshot" ``` --- ## Step 3: Prompt Assembly For each RCA executor: ``` ORIGINAL REQUEST: {user's bug description from conversation} --- You are executing the ROOT CAUSE ANALYSIS stage. Diagnose the bug described above. Do NOT fi

Root cause analysis for bugs. Dispatches RCA executors in parallel, consolidates findings, and appends RCA Diagnosis to the plan file.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill dev-buddy-rca --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
