rca-annotator

rca-annotator is a skill for Claude Code from redhat-et/rhdp-rca-plugin. It costs 35 tokens per session (2,168 once invoked), scanned A, original, Apache-2.0.

A structured review tool for labeling the results of a root-cause analysis, which is an investigation into why a failure happened. It records whether a diagnosis is correct, how strong its evidence is, how difficult the case was, and possible alternatives.

In plain words
What is it for?
Use it after a root-cause-analysis run to annotate the diagnosis and save the review as structured annotation data.
Why use it?
It helps turn human review of failure investigations into consistent data for evaluation, benchmarking, or building datasets.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

rca-annotator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/cli.py, scripts/jumpbox_io.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

RCA Annotator

A structured annotation tool that presents the root-cause-analysis agent's diagnosis to the user and guides them through labeling it — capturing whether the diagnosis is correct, evidence quality, difficulty, and alternative hypotheses.

root-cause-analysis (Agent) rca-annotator (Annotation tool)
Purpose Diagnose failures for users Capture human-labeled ground-truth data
Reads Logs, Splunk, GitHub (live) Step 1/3/4/5 output files (offline)
Output Human-readable diagnosis Structured annotation.json

Use when: a root-cause-analysis run is complete and you want to annotate its output as correct, incorrect, or partially correct — for evaluation, benchmarking, or dataset building.

Do NOT use to perform initial RCA (use root-cause-analysis).

Prerequisites

Verify root-cause-analysis has been completed.

  • JUMPBOX_URI (optional) — SSH connection string (e.g. "user@host -p 2222"). If unset, uses local .analysis/ only.
  • SSH keys configured in ~/.ssh/config if using jumpbox; ssh and rsync installed.
  • Required files in .analysis/<job_id>/:
    • step5_summary.json — Agent's final diagnosis (primary input)
    • step1_job_context.json — Job metadata, failed tasks
    • step3_correlation.json — Timeline with AAP + Splunk events
    • step4_github_fetch_history.json — Configuration and code context

If missing, run root-cause-analysis skill first.

Workflow

  1. Download from jumpbox (if JUMPBOX_URI set) or verify local files
  2. Read step5_summary.json — present the agent's diagnosis to the user
  3. Walk through annotation questions interactively — the user labels each section
  4. Write annotation.json with the user's labels
  5. Upload to jumpbox (if JUMPBOX_URI set)

Step 0: Download Analysis Files

cd skills/rca-annotator
python scripts/cli.py download --job-id <job_id>

Downloads from jumpbox /usr/local/mlflow/<job_id>/ to local .analysis/<job_id>/. If JUMPBOX_URI unset, validates local files only. Errors on missing remote directory, missing required files, or connection failure.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
