/baseline -- Baseline Measurement Skill

Skill ID: onex:baseline
Version: 2.0.0
Backing nodes: node_baseline_capture, node_baseline_compare

Changelog

• 2.0.0 — Thinned to dispatch-only shim. All logic in node_baseline_capture and node_baseline_compare. Replaced direct Python handler imports with onex run-node dispatch.
• 1.0.0 — Original skill with direct Python handler imports.

Usage

/baseline capture [baseline_id] [--probes pr,tickets,health] [--label "description"]
/baseline compare [baseline_id] [--probes pr,tickets]
/baseline report [baseline_id]

Announce at start: "I'm using the baseline skill."

Behavior

capture

Dispatches node_baseline_capture to snapshot current system state.

uv run onex run-node node_baseline_capture --input '{
  "baseline_id": "<baseline_id>",
  "probes": ["github_prs", "linear_tickets", "system_health", "git_branches"],
  "label": "<label>",
  "dry_run": false
}'

• Terminal event: onex.evt.omnimarket.baseline-captured.v1
• Artifact written to: .onex_state/baselines/{baseline_id}.json
• Reports: probes run, probes failed, artifact path

compare

Dispatches node_baseline_compare to load the baseline artifact, re-capture current state, and diff per probe.

uv run onex run-node node_baseline_compare --input '{
  "baseline_id": "<baseline_id>",
  "dry_run": false
}'

• Terminal event: onex.evt.omnimarket.baseline-compared.v1
• Artifact written to: .onex_state/baselines/{baseline_id}.delta.json
• Reports: summary paragraph + per-probe delta counts table

report

Reads existing .delta.json artifact and displays in chat. No re-capture. No dispatch needed — read the artifact directly from .onex_state/baselines/{baseline_id}.delta.json.

Default Probes

github_prs, linear_tickets, system_health, git_branches

Optional (require infra): kafka_topics, db_row_counts

Example -- Overnight Workflow

Before work:

/baseline capture overnight-2026-04-09 --label "before overnight run"

After work:

/baseline compare overnight-2026-04-09

On non-zero exits, surface the SkillRoutingError JSON envelope directly; do not produce prose.
