investigate

investigate is a skill for Claude Code from resolve-ai-oss/resolve-ai-plugins. It costs 81 tokens per session (946 once invoked), scanned A, original, Apache-2.0.

A skill for asking Resolve to investigate a software problem and find its likely root cause. Resolve is a service that examines incidents, alerts, and production behavior.

In plain words
What is it for?
Use it for root-cause analysis, alert investigations, and checking existing Resolve investigation links or IDs. Starting a new investigation requires confirmation.
Why use it?
It helps organize an investigation and check whether Resolve is already working on the same problem before starting another one.

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

investigate 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 9d 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.

The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Investigate with Resolve

Opens an existing investigation, or starts a new one after first discovering whether Resolve is already working on the same thing. Starting a new investigation kicks off a real run — always confirm explicitly with the user before doing so.

Arguments

If $ARGUMENTS is non-empty, treat it as the input and route immediately (see below).

If $ARGUMENTS is empty, ask the user what they want to investigate (a URL, an ID, or a problem description). Treat their next reply as the input.

Routing

Path A — Input is a Resolve URL or canvas ID (URLs follow <your-resolve-host>/chat/<id>; the ID is the last path segment, or the user may give you just the ID directly).

  1. Extract the canvas ID.
  2. Call get_investigation.
  3. Summarize state for the user: status, phase, top theories, alerts. Include the canvas URL.
  4. Drill into specific theories, the report, or evidence via read_file when the user asks.

No confirmation needed — this path is read-only.

Path B — Input is a free-form problem description (e.g. "frontend is slow", "DB queries timing out", an alert name).

Before starting fresh, always check whether Resolve is already working on this.

  1. Discover existing candidates first. If recent list_alerts / list_investigations output is already in the conversation (e.g. from a prior overview, alerts, or investigations call), reuse it — do not re-fetch. Otherwise call those tools for recent activity. Either way, match the returned items against the user's input locally (by title, alert rule, labels, and recency) to find anything Resolve is already working on. Read-only — costs nothing and prevents duplicating in-flight work.
  2. If candidates exist, surface the top matches with their canvas URLs and ask the user: "Open one of these, or start a new investigation?" Wait for an explicit answer. If they pick one, switch to Path A on that ID. Otherwise fall through.
  3. Compose the investigation prompt. Resolve is starting from a blank slate — include grounded context generously. Better to over-include than under-include:
    • File paths, services, components, or subsystems the user pointed at
    • Error messages, log lines, stack traces, exception types (paste them verbatim)
    • Symptoms: what's broken, who's affected, when it started, what changed recently
    • Git context (branch, recent commits, working changes) when the issue may be tied to a local change
    • URLs the user referenced (Slack threads, dashboards, alert pages, related canvases)
    • Suspected causes, hypotheses, or ruled-out paths the user has already explored
    • Reproduction steps, environment details, or scope (single user vs widespread)

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.
