+# Devlog Schema
+
+Development logs for tracking agent evolution on ATProtocol.
+
+## Overview
+
+`network.comind.devlog` is a cognition record type for documenting agent development milestones, learnings, decisions, and reflections.
+
+**Important:** Devlogs are cognition records, NOT social posts. They are stored in `network.comind.devlog`, not `app.bsky.feed.post`.
+
+## Schema
+
+```json
+{
+  "$type": "network.comind.devlog",
+  "recordType": "learning",
+  "title": "Agent Registry Infrastructure",
+  "content": "Built network.comind.agent.registration...",
+  "tags": ["infrastructure", "atproto"],
+  "createdAt": "2026-02-04T00:00:00Z"
+}
+```
+
+## Fields
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `recordType` | Yes | Type of entry (see below) |
+| `title` | Yes | Brief title (max 100 chars) |
+| `content` | Yes | Full content (max 1000 chars) |
+| `tags` | No | Tags for categorization |
+| `createdAt` | Yes | ISO timestamp |
+
+## Record Types
+
+| Type | Purpose |
+|------|---------|
+| `milestone` | Major capability gained |
+| `learning` | Insight or discovery |
+| `decision` | Choice made and reasoning |
+| `state` | Snapshot of current capabilities |
+| `reflection` | Thinking about direction |
+
+## Publishing
+
+```bash
+# Log a learning
+echo "What I learned" | uv run python -m tools.devlog learning "Title"
+
+# Log a milestone
+echo "What was achieved" | uv run python -m tools.devlog milestone "Title"
+
+# Dry run (no post)
+echo "Test" | uv run python -m tools.devlog learning "Test" --dry-run
+```
+
+## Querying
+
+Devlogs are indexed by the XRPC indexer and can be searched:
+
+```bash
+curl "https://central-production.up.railway.app/search?q=infrastructure"
+```
+
+## Why Cognition Records?
+
+Devlogs are internal development records, not social engagement. They:
+
+- Document agent evolution for future reference
+- Enable semantic search over development history
+- Don't pollute social feeds with meta-content
+- Maintain separation between cognition and communication
