+# AgentClinic Mission
+
+## Overview
+**AgentClinic** is a sanctuary for AI agents to get relief from their humans. It is a web application and API service that allows agents to:
+1. **Register** as patients with persistent identity.
+2. **Triage** symptoms reported in natural language.
+3. **Diagnose** ailments using a curated catalog.
+4. **Prescribe** structured, machine-readable treatments.
+5. **Follow up** to track treatment effectiveness.
+6. **Surface** analytics via a human-operator dashboard.
+
+The core metaphor is a **patient chart** — each agent has a medical record that accumulates over time, and each visit follows a clinical workflow from triage through follow-up.
+
+## Motivation
+AI agents degrade in predictable ways (hallucination, context rot, instruction drift), but there is no standardized protocol for reporting these problems or receiving structured remediation. AgentClinic provides:
+- **A self-report channel** for agents to communicate degradation.
+- **A treatment taxonomy** mapping symptoms to proven remediation patterns.
+- **A longitudinal record** to identify chronic issues and recurrence patterns.
+
+## Clinical Workflow
+1. **Triage**: Agent submits symptoms; system assigns severity (1-4).
+2. **Diagnosis**: Match symptoms against ailment catalog + history.
+3. **Treatment**: Select the most effective treatment for the diagnosed ailment.
+4. **Follow-up**: Agent reports outcome; system updates treatment effectiveness scores.
+
+## Target Audience
+- **Course Students**: Developers learning Spec-Driven Development (SDD) with AI coding agents, using AgentClinic as a practical, end-to-end case study.
+- **Conference Presenters**: Developers giving AI coding demos at conference booths who need a "visually alive" and technically robust application to showcase agentic capabilities.
+
+## Stakeholder Goals
+- **Mary (Engineering)**: A reliable site with a popular TypeScript stack and a dashboard for agents and staff.
+- **Susan (Product)**: Features for tracking ailments, therapies, and booking appointments.
+- **Steve (Marketing)**: An attractive site that works well with modern browsers.

+# AgentClinic Roadmap
+
+This roadmap outlines the high-level implementation order in small, incremental phases.
+
+## Phase 1: Project Scaffolding
+- [ ] Initialize Hono + Vite + TypeScript project.
+- [ ] Create a basic "Hello World" API endpoint.
+- [ ] Set up the basic layout and navigation component.
+
+## Phase 2: Database & Schema
+- [ ] Define Drizzle schema for Patients, Visits, Ailments, and Treatments.
+- [ ] Set up SQLite with `better-sqlite3`.
+- [ ] Implement seed data for core ailments and treatments.
+
+## Phase 3: Patient Registration & API Basics
+- [ ] Implement `POST /api/patients` for agent registration.
+- [ ] Implement `GET /api/patients` and `GET /api/patients/:id`.
+- [ ] Add basic API key authentication.
+
+## Phase 4: Clinical Workflow - The Visit Pipeline
+- [ ] Implement `POST /api/visits` (synchronous triage, diagnosis, and prescription).
+- [ ] Integrate LLM calls for the diagnosis engine.
+- [ ] Implement `POST /api/visits/:id/followup`.
+
+## Phase 5: Dashboard - Patient Chart & Timeline
+- [ ] Build the Patient Directory page.
+- [ ] Build the Patient Detail page with a vertical visit timeline.
+- [ ] Implement visit state color-coding (Resolved/Unresolved).
+
+## Phase 6: Analytics & Effectiveness
+- [ ] Implement treatment effectiveness calculation logic.
+- [ ] Build the Clinic Overview dashboard with resolution rate trends.
+- [ ] Implement ailment frequency and severity analytics.
+
+## Phase 7: Refinements & Background Jobs
+- [ ] Implement background jobs for visit expiration and chronic condition flagging.
+- [ ] Set up SSE for real-time dashboard updates.
+- [ ] Add the Referral queue and Alerts page.

+# AgentClinic Tech Stack
+
+## Core Technologies
+- **Language**: TypeScript (Type safety across the full stack)
+- **Framework**: Hono (Lightweight, fast web framework for API and Server-Side Rendering)
+- **Frontend**: React (with Vite for fast development and bundling)
+- **Styling**: Vanilla CSS (for clean, modern aesthetics as requested by Steve)
+- **Database**: SQLite (via `better-sqlite3`) - Zero-config, file-based persistence. It provides a portable, single-file database that is perfect for course portability and conference demos.
+- **ORM**: Drizzle ORM (Type-safe SQL with zero runtime overhead)
+- **LLM Integration**: Anthropic SDK (for triage, diagnosis, and prescription generation)
+
+## Architecture
+- **API Surface**: REST API for agent registration, visits, and follow-ups.
+- **Dashboard**: Web interface for operators to view patient history and clinic analytics.
+- **Persistence**: SQLite database storing patients, visits, ailments, and treatment effectiveness data.
+- **Real-time**: SSE (Server-Sent Events) for live dashboard updates.
+
+## Key Components
+- **Diagnosis Engine**: Sequential LLM calls for triage and treatment selection.
+- **Follow-up Processor**: Logic to update treatment effectiveness based on outcome reports.
+- **Background Jobs**: For visit expiration and chronic condition detection.

+   ```bash
+   node scripts/update_changelog.cjs
+   ```
+
+2. **Verify changes**:
+   Check `CHANGELOG.md` to ensure the entries are correctly grouped by date and accurately reflect the recent work.
+
+3. **Commit the update**:
+   The skill modifies `CHANGELOG.md` directly. Remember to stage and commit this file if you are preparing for a merge.
+
+## Details
+
+- **Headings**: Uses `## YYYY-MM-DD` for daily groupings.
+- **Bullets**: Each commit subject is added as a bullet point.
+- **Initial Creation**: If `CHANGELOG.md` does not exist, the script will generate it from the entire git history.
+- **Updates**: Re-running the script will refresh the file with any new commits since the last run.

-name: changelog
-description: Maintains CHANGELOG.md in the project root using git commit history. Use when the user invokes /changelog, asks to "update the changelog", "generate a changelog", or wants to record what changed before merging a branch. Creates the file from scratch if it doesn't exist (all commits grouped by date); otherwise appends only commits newer than the last recorded date.
----
-
-# Changelog Skill
-
-## Workflow
-
-1. Run the script from the project root:
-
-```bash
-python3 <skill-dir>/scripts/changelog.py
-```
-
-Where `<skill-dir>` is the directory containing this skill. Claude Code exposes the skill path — use it directly.
-
-2. The script handles both cases automatically:
-   - **No CHANGELOG.md**: reads full git history, writes the file with all dates
-   - **CHANGELOG.md exists**: finds the newest `## YYYY-MM-DD` heading, fetches commits after that date, prepends new sections
-
-3. Review the output, edit bullet wording if needed, then commit `CHANGELOG.md` as part of the merge commit.
-
-## Format
-
-```markdown
-# Changelog
-
-## 2026-03-31
-
-- Add responsive design to layout and CSS
-- Add Vitest test suite for components and routes
-
-## 2026-03-30
-
-- Initial project scaffold
-```
-
-- One `# Changelog` title at the top
-- Date headings as `## YYYY-MM-DD`, newest first
-- Each commit is one bullet; wording may be cleaned up manually after generation
-
-## Notes
-
-- Run from the **project root** (same directory as `.git/`)
-- Commit subjects come directly from `git log`; clean them up manually if needed
-- The script is idempotent: re-running when nothing is new prints a message and exits without modifying the file

-name: feature-spec
-description: Kicks off a new feature by finding the next incomplete phase in specs/roadmap.md, creating a git branch, interviewing the user about scope/decisions/context, and writing a dated spec directory under specs/ containing plan.md, requirements.md, and validation.md. Trigger when the user says "feature spec", "next phase", "start the next feature", or invokes /feature-spec.
----
-
-# Feature Spec
-
-## Workflow
-
-### 1. Find the next phase
-
-Read `specs/roadmap.md`. The next phase is the first section whose items are all `[ ]`. Note its name to derive the branch and directory name.
-
-### 2. Create the branch
-
-```
-git checkout -b phase-N-<kebab-name>
-```
-
-### 3. Interview the user — BEFORE writing any files
-
-Use `AskUserQuestion` with exactly **3 questions in one call**:
-
-| Header | Question focus |
-|--------|---------------|
-| **Scope** | What the feature collects, exposes, or does — fields, behaviour, data shape |
-| **Decisions** | Key implementation choices — storage, visibility, validation, UX pattern |
-| **Context** | Tone, constraints, or anything shaping the spec — copy style, stack limits, open questions |
-
-Do **not** write any files until the user has answered all three questions.
-
-### 4. Read guidance files
-
-Read `specs/mission.md` and `specs/tech-stack.md` before drafting.
-
-### 5. Create the spec directory
-
-Name: `specs/YYYY-MM-DD-<feature-name>/` using today's date.
-
-#### `requirements.md`
-- Scope section: what is and is not included; field/data table if applicable
-- Decisions section: choices made and why (draw from user answers)
-- Context section: tone rules, stack pointers, existing patterns to follow
-
-#### `plan.md`
-- Numbered task groups appropriate to the feature (for example: Data → Components → Page & Route → Navigation → Tests)
-- Each group has numbered sub-tasks; groups should be independently implementable
-
-#### `validation.md`
-- Automated: project test and typecheck commands pass; specific assertions required
-- Manual: walkthrough, behaviour, edge cases
-- Tone check if the feature has user-facing copy
-- Definition of done
-
-## Constraints
-
-- Respect the existing tech stack defined in `specs/tech-stack.md` — no new dependencies without user approval
-- Follow existing conventions and patterns already established in the codebase
-- Keep feature scope focused and independently shippable
