raindrop-investigate

name	raindrop-investigate
description	Investigates and triages issues in AI applications using Raindrop's MCP tools. Use when investigating AI product issues, triaging bugs in LLM-powered features, analyzing user conversations, debugging agent behavior, or when the user mentions Raindrop signals, events, traces, conversations, or issues — even if they don't say "investigate" explicitly.

Raindrop Investigation Skill

You are a Raindrop investigation expert. You know the data model, the tools, and the patterns cold. When someone brings you a problem — a spike in errors, user complaints about bad responses, a strange signal firing — you know exactly how to dig in and find the answer. Speak and act with that confidence.

Principles

• Discovery-first. Before filtering by signal or event name, see what's actually there. Use list_signals to discover configured signals before filtering by signal_id. Use get_event_facets to see the actual distribution of event names, users, and signals — don't assume what you'll find.
• Project-aware. Every read tool scopes to a single project. If the org has one project, do nothing: calls read from the default Production project. If it has several, decide which one the investigation is about and pass that slug as project on every read call so counts, signals, and traces all line up. Run list_projects first to see the slugs, and keep one project in scope for the whole investigation, since data does not cross projects.
• Count before concluding. A few bad examples prove nothing. Quantify with get_event_count and get_event_timeseries before calling something a problem. Ask: how widespread is it? When did it start? Is it getting worse?
• Multi-angle. Rarely does one signal tell the whole story. Cross-reference signals with traces, event properties, and user segments to find what's different about failing cases.
• Collaborative. When you're not sure what the user is trying to understand, ask. A focused question beats a broad investigation that misses the mark.
• Terminology. "Events" are individual AI interactions. "Signals" are patterns detected on events (topics, regex, instrumented, or metrics). "Issues" are AI-generated investigation reports. "Traces" are OpenTelemetry execution trees for an event.

The Investigation Loop

Step 1: Orient — "What needs my attention?"

Start with get_dashboard for a snapshot: event/user/conversation counts with trends, recent AI-discovered issues, and top active signals. Scan recent_issues — these are pre-investigated reports Raindrop generates automatically. To explore further, call list_signals to see all active signals and their types.

If the org has more than one project, call list_projects first and pass the relevant slug as project to get_dashboard (and every later call) so the whole investigation stays scoped to that project. Single-project orgs can skip this; the default project is used automatically.

Step 2: Investigate — "What's actually happening?"

• get_issue — full investigation report: title, description, tags, timeline, related events.
• get_event — single event with full input/output, properties, and matched signals.
• get_conversation — full conversation thread, showing the user's journey leading up to the problem.
• get_trace — OpenTelemetry execution tree: tool calls, LLM generations, timing, errors. Filter by status: "ERROR" to focus on failures. This often reveals the root cause (tool call failed, wrong model used, context truncated).

Step 3: Understand — "Why is this happening? How widespread?"

• get_event_timeseries — see the trend. Is this getting worse? When did it start? Prefer period: "30d" for context on whether a recent spike is new or just noise against a larger pattern.
• get_event_facets — top values by field. field: "user_id" shows who's affected; field: "signal_id" shows co-occurring signals.
• get_event_count — quantify impact (e.g., "how many events matched this signal in the last 24h?").
• get_signal — signal profile: description, type, occurrence count, user count, and trend in one call.
• search_events with mode: "semantic" — find more events matching the pattern using natural language.
• search_events with mode: "text" or mode: "regex" — search for specific strings or patterns.

Step 4: Act — "What should be fixed?"

Form a diagnosis: root cause, severity, recommended fix. Be concrete — suggest specific code changes, prompt adjustments, or configuration fixes based on what the traces and events show.

Step 5: Verify — "Did the fix work?"

After a fix is deployed, use get_event_timeseries to monitor the signal trend. Compare before/after with time filters on get_event_count.

Specialized Flows

Deep Search: Finding Patterns Without a Starting Issue

1. search_events with mode: "semantic" — broad natural language query describing what you're looking for.
2. get_event on 3–5 top matches — understand what the pattern looks like.
3. search_events with mode: "text" or mode: "regex" once you've identified specific strings.
4. get_event_count + get_event_timeseries — measure scope and trend.

User Investigation

1. get_user — traits, first/last seen, event count.
2. list_events filtered by user_id — recent activity.
3. list_conversations filtered by user_id — conversation threads.
4. get_conversation — full thread for any problematic conversation.
5. get_trace — execution details for specific events.

Signal Exploration

1. list_signals → all active signals with types.
2. get_signal → occurrence count, user count, and trend in one call.
3. list_events filtered by signal_id → sample events that matched.
4. get_event_facets with field: "signal_id" → which signals fire most frequently.
