cross-source-correlation

cross-source-correlation is a skill for Claude Code, Codex from aozyildirim/Agena. It costs 64 tokens per session (801 once invoked), scanned A, original, MIT.

A tool for comparing events from code changes, deployments, monitoring systems, and issue trackers within the same time window. It groups related events into confidence-scored incident clusters.

In plain words
What is it for?
Use it during incident investigation to correlate pull-request merges, deployments, error alerts from services such as Sentry or Datadog, and tickets from Jira or Azure DevOps.
Why use it?
It reduces the manual work of switching between systems to determine which code change or deployment may have caused a bug.

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

cross-source-correlation 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 8d ago.

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.

Cross-Source Correlation

When a Sentry alert fires, a senior engineer mentally cross-references the last deploy time, recent PRs, NewRelic apdex, and the support tickets opened in the last hour. AGENA's Cross-Source Correlation engine does the same correlation deterministically, producing a single confidence-scored cluster per incident.

How to apply this pattern

  1. Pick a time window (default 60 minutes ending now) and pull every event your platform observed inside it: PR merges, deploys, error imports (Sentry / NewRelic / Datadog / AppDynamics), and work-item imports (Jira / Azure DevOps).

  2. Score candidate clusters using a heuristic that rewards co-location in time + repo:

    • PR merge inside the window → +40
    • Deploy from the same repo inside the window → +20
    • One monitoring signal in the window → +20 (+30 if more than one)
    • One work-item opened in the window → +10 (+20 if more than one)
    • Bonus +10 when a PR is present alongside any monitoring signal
  3. Surface only clusters ≥ 70. Below that the noise / signal ratio collapses; above it you get the "vay" moment for incident triage.

  4. Persist the cluster with: primary_kind, primary_label, related_events[], confidence, severity, narrative, repo_mapping_id. Keep a fingerprint for idempotency so repeated poller runs don't double-insert the same cluster.

  5. Offer triage actions on each cluster: confirm, false-positive, undo, and (when a PR is the prime suspect) one-click rollback.

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.
