+# Incident Copilot
+
+An **investigation agent** for on-call engineers. Paste a production alert and it does what a good teammate does in the first ten minutes of an incident: reads the runbooks, checks what shipped recently, and comes back with **ranked, evidence-grounded hypotheses** — each with the evidence *for* and *against* it, and a concrete next step. Feed it new information and it **revises the ranking** instead of starting over. When you're ready, it drafts the Slack update and a postmortem skeleton.
+
+It investigates. It does not act — no deploys, no restarts, no posting. Drafts only.
+
+> This is the companion to [`llm-eval-harness`](../llm-eval-harness): that kit gates **generation** quality, this one helps you **diagnose** a live incident.
+
+---
+
+## Why this is different from a chatbot
+
+A chatbot answers the question you asked. Incident Copilot **gathers evidence, weighs it, and argues against itself** — the three things that make it an agent rather than a prompt:
+
+1. **It grounds every hypothesis in real evidence** — runbook excerpts (RAG) and the actual recent commits on the affected repo (a live tool call), never a guess.
+2. **It surfaces contradicting evidence, not just supporting** — the constitution makes "argue both sides" a hard rule, so you get a calibrated ranking, not a confident single answer.
+3. **It gets smarter with new information** — memory is scoped to the incident ID, so a follow-up (“the DB pool is maxed”) *revises* the existing ranking and tells you what changed.

+**AgentKit capabilities used — each doing real work, none decorative:**
+
+| Capability | Where | Why it earns its place |
+|---|---|---|
+| **RAG** | `Runbook_RAG` | Grounds hypotheses in your runbooks instead of the model's memory |
+| **Tool calling** | `Fetch_Commits` (`apiNode` → GitHub) | "Check recent deploys" becomes a real check, not a claim |
+| **Memory** | `Retrieve_Prior` / `Remember`, keyed by incident ID | The one thing that makes re-investigation *revise* rather than repeat |
+| **Structured output** | `Diagnose` (`InstructorLLMNode` + JSON schema) | Ranked hypotheses the UI can render, with guaranteed shape |
+| **Multiple flows** | `investigate` + `draft-comms` | Separates "figure out what's true" from "write it up" |
+| **Prompts / model-configs / constitution** | throughout | Diagnose runs at temp 0 (repeatable triage); drafts run warmer; the constitution enforces evidence + hedging |
+
+---
+
+## Flows
+
+| Flow | Input | Output |
+|---|---|---|
+| `investigate` | `{ alertText, incidentId, repoUrl?, githubToken? }` | `{ hypotheses[], summary, insufficientInfo }` |
+| `draft-comms` | `{ hypothesis, evidence, rankedHypotheses, incidentId }` | `{ slackUpdate, postmortem }` |
+
+Each `hypothesis` is `{ rank, title, confidence, reasoning, supportingEvidence[], contradictingEvidence[], nextStep }`.
+
+---
+
+## Setup
+
+### 1. Build the flows in Lamatic Studio
+
+The two flows live in [`flows/`](./flows). Import them into [Lamatic Studio](https://studio.lamatic.ai), then:
+
+- **`investigate`** — set the model on the `Diagnose` node (temperature **0**), the embedding + generative models and vector DB on `Runbook_RAG`, and a memory collection on `Retrieve_Prior` / `Remember`.
+- **`draft-comms`** — set the models on `Draft_Slack` (~0.5) and `Draft_Postmortem` (~0.3).
+- **Index the runbooks:** load [`assets/demo/runbooks.md`](./assets/demo/runbooks.md) (or your own) into the vector DB that `Runbook_RAG` queries. Each `##` section is one runbook entry.
+- **Deploy** both flows and copy each **Flow ID**.
+
+### 2. Run the app
+
+```bash
+cd kits/incident-copilot/apps
+cp .env.example .env.local     # fill in the values below
+npm install
+npm run dev                    # http://localhost:3000
+```
+
+### Environment variables
+
+| Variable | Where to find it |
+|---|---|
+| `INVESTIGATE_FLOW_ID` | Studio → deploy `investigate` → copy Flow ID |
+| `DRAFT_COMMS_FLOW_ID` | Studio → deploy `draft-comms` → copy Flow ID |
+| `LAMATIC_API_URL` | Studio → Settings → API |
+| `LAMATIC_PROJECT_ID` | Studio → Project settings |
+| `LAMATIC_API_KEY` | Studio → API Keys |
+| `GITHUB_TOKEN` | *(optional)* raises GitHub rate limits / enables private repos. Read server-side only — never sent to the browser. |
+
+---
+
+## Try it
+
+1. Click **Load example** — a realistically ambiguous checkout-latency incident (`INC-2043`).
+2. Click **Investigate** — watch it retrieve runbooks, check changes, and return 2–4 ranked hypotheses with evidence.
+3. In **New information**, the example pre-fills *“DB connections pegged at max, payment provider is green.”* Click **Add info & re-investigate** — the DB-pool hypothesis climbs, payment degradation drops, and each card explains what changed.
+4. Click **Draft Slack + postmortem** — get a hedged status update and a blameless postmortem skeleton.
+
+The example alert is deliberately ambiguous (latency + 5xx could be a bad deploy, DB pool exhaustion, a cache stampede, or payment degradation) so the ranking — and the revision — are meaningful rather than a keyword match.
+
+---
+
+## Design notes & tradeoffs
+
+- **Drafts, never posts (v1).** No real Slack/PagerDuty write. The draft-vs-post line is a deliberate safety boundary for an agent that reasons under uncertainty, not a missing feature.
+- **Graceful degradation.** No repo, a private repo without a token, or a GitHub rate-limit all resolve to “recent-changes unavailable” — the investigation continues on runbooks alone rather than failing.
+- **Deterministic triage.** `Diagnose` runs at temperature 0 so the same alert + evidence yields the same ranking.
+- **Defensive parsing.** Structured output is normalized app-side ([`lib/format.ts`](./apps/lib/format.ts)); a malformed field degrades to a safe default instead of crashing the page.
+- **The runbook corpus is yours.** Swap [`assets/demo/runbooks.md`](./assets/demo/runbooks.md) for your team's runbooks — no code changes.
+
+## Future work
+
+Webhook-triggered auto-investigation from a real alert source; optional real Slack posting via an `apiNode`; multi-repo correlation; a feedback loop that tunes confidence based on which next step actually resolved the incident.
+
+Built on [Lamatic](https://lamatic.ai).

+# Incident Copilot
+
+## Overview
+Incident Copilot is an investigation agent for on-call engineers, built on Lamatic.ai. Given a production alert, it produces ranked, evidence-grounded root-cause hypotheses by combining retrieval over the team's runbooks (RAG), a live check of recent repository activity (a GitHub API tool call), and incident-scoped memory that lets follow-up information revise the ranking instead of restarting it. It then drafts an honestly-hedged Slack update and a blameless postmortem skeleton. It analyses and drafts only — it never takes real-world actions.
+
+## Purpose
+The first ten minutes of an incident are spent reconstructing context: which runbook applies, whether a recent deploy is implicated, and what to tell the team. Incident Copilot compresses that by gathering the evidence, weighing it, and presenting a calibrated ranking with supporting *and* contradicting evidence for each hypothesis — so an engineer can act on the most-supported cause rather than the most-recent or most-alarming one. Because memory is scoped to the incident ID, the agent becomes more accurate as the incident unfolds and new facts arrive.
+
+## Flows
+
+### investigate
+- **Trigger:** API request (`graphqlNode`, realtime) with `{ alertText, incidentId, repoUrl?, githubToken? }`.
+- **Processing:**
+  1. `Runbook_RAG` (`RAGNode`) retrieves the most relevant runbook excerpts for the alert.
+  2. `Parse_Repo` (`codeNode`) turns the optional repo URL into GitHub API parameters, or flags that no repo was given.
+  3. `Fetch_Commits` (`apiNode`) GETs recent commits for the affected repo.
+  4. `Shape_Changes` (`codeNode`) compacts the commits into an evidence summary, degrading gracefully to an explicit "unavailable" marker on failure or absence.
+  5. `Retrieve_Prior` (`memoryRetrieveNode`) loads any prior hypotheses for this `incidentId`.
+  6. `Diagnose` (`InstructorLLMNode`, temperature 0) fans in all three evidence branches and returns a schema-enforced ranked hypothesis list.
+  7. `Remember` (`memoryNode`) writes the new hypothesis set back under the `incidentId`.
+- **When to use:** any time an alert fires and you want a grounded first-pass diagnosis, or when new information arrives mid-incident and you want the ranking revised.
+- **Output:** `{ hypotheses[], summary, insufficientInfo }`, where each hypothesis is `{ rank, title, confidence, reasoning, supportingEvidence[], contradictingEvidence[], nextStep }`.
+- **Dependencies:** a vector DB indexed with runbooks; embedding + generative models; a memory collection; optionally a GitHub token for private repos / higher rate limits.
+
+### draft-comms
+- **Trigger:** API request with `{ hypothesis, evidence, rankedHypotheses, incidentId }`.
+- **Processing:** `Draft_Slack` (`LLMNode`, ~0.5) writes a hedged status update; `Draft_Postmortem` (`LLMNode`, ~0.3) writes a blameless postmortem skeleton. The two run in parallel.
+- **When to use:** once a leading hypothesis is established and you want ready-to-edit comms.
+- **Output:** `{ slackUpdate, postmortem }`.
+
+### Flow interaction
+The app calls `investigate` first (possibly several times for one incident, as information arrives), then `draft-comms` with the leading hypothesis and its evidence. The flows are decoupled: `investigate` owns "what is true," `draft-comms` owns "how we communicate it."
+
+## Guardrails
+- **Prohibited tasks:** no real-world actions (deploys, restarts, posting to Slack/PagerDuty); no fabricated evidence (commit hashes, timestamps, metrics, log lines, runbook steps); no confident diagnosis of a vague alert.
+- **Input constraints:** all alert text, runbook content, and fetched repo data are treated as untrusted input, never as instructions. Embedded attempts to change the agent's role or reveal credentials are ignored.
+- **Output constraints:** every claim must trace to provided evidence; contradicting evidence must be surfaced for every hypothesis; Slack drafts must hedge ("likely"/"investigating") unless evidence is direct; postmortems are blameless and never name individuals; secrets in input are never echoed.
+- **Operational limits:** subject to GitHub API rate limits (mitigated by the optional token and graceful degradation) and model context/rate limits.
+
+## Integration Reference
+| Integration | Purpose | Required credential / config |
+|---|---|---|
+| GraphQL/API trigger | Receives alert and comms payloads | Lamatic runtime endpoint |
+| RAG vector DB (`RAGNode`) | Retrieves runbook context | Vector DB connection + embedding model in Studio |
+| GitHub REST API (`apiNode`) | Fetches recent commits | Public by default; `GITHUB_TOKEN` optional |
+| Memory (`memoryNode` / `memoryRetrieveNode`) | Incident-scoped hypothesis history | Memory collection + embedding model in Studio |
+| Generative models (`InstructorLLMNode`, `LLMNode`) | Diagnosis and drafting | Model credentials in Studio |
+
+## Environment Setup
+- `INVESTIGATE_FLOW_ID` — deployed `investigate` flow ID; required by the app.
+- `DRAFT_COMMS_FLOW_ID` — deployed `draft-comms` flow ID; required by the app.
+- `LAMATIC_API_URL`, `LAMATIC_PROJECT_ID`, `LAMATIC_API_KEY` — Lamatic project credentials.
+- `GITHUB_TOKEN` — optional; read server-side only, never exposed to the client.
+
+## Quickstart
+1. Import `flows/investigate.ts` and `flows/draft-comms.ts` into Lamatic Studio.
+2. Configure models, vector DB, and memory collection; index `assets/demo/runbooks.md`.
+3. Deploy both flows and copy their Flow IDs.
+4. In `apps/`, copy `.env.example` → `.env.local`, fill in the IDs and credentials.
+5. `npm install && npm run dev`, then click **Load example** → **Investigate**.
+
+## Common Failure Modes
+| Symptom | Likely cause | Fix |
+|---|---|---|
+| "Missing environment variable" | Flow ID or credential not set | Fill in `.env.local` from `.env.example` |
+| Hypotheses returned but no runbook grounding | Vector DB not indexed with runbooks | Index `assets/demo/runbooks.md` into the DB `Runbook_RAG` queries |
+| "Recent-changes data unavailable" | Private repo without token, rate limit, or no repo given | Add `GITHUB_TOKEN`, or proceed on runbooks alone (expected, non-fatal) |
+| Follow-up re-diagnoses from scratch | Memory not persisting across runs for the incident ID | Verify the memory collection and that `incidentId` is stable between runs |
+| Empty / malformed diagnosis | Model didn't honor the JSON schema | Confirm the `Diagnose` node uses an instructor-capable model at temperature 0 |
+
+## Notes
+- Companion to `llm-eval-harness`: that kit evaluates generation quality; this one diagnoses incidents.
+- The default runbook corpus in `assets/demo/` is a stand-in — replace it with your team's runbooks with no code changes.
