Keep project documentation synchronized and hierarchical across the index, functional specs, and technical docs, updating it after code changes.
About
Maintains a hierarchical documentation system with a single source of truth, enforcing separation of functional versus technical docs and bidirectional link consistency. A developer uses it when creating, updating, reorganizing, or syncing docs, ideally after successful code changes.
- No-duplication rule: write once, link everywhere else
- Separates functional (what/why) from technical (how) docs with hierarchical linking

What it does
Keep project documentation synchronized and hierarchical across the index, functional specs, and technical docs, updating it after code changes.
Files
Doc Sync
Maintain synchronized, hierarchical project documentation following a structured system where high-level documents link to detailed specifications, requirement specs remain implementation-agnostic, and technical docs reference features appropriately.
Key principle: If code changed successfully and will be kept, docs should be updated to match user-observable behavior. Internal implementation details that don't affect how users interact with or understand the system don't require documentation updates.
Always invoke this skill before committing changes to version control.
Do NOT invoke for:
- Exploratory/debugging work that doesn't lead to changes
- Temporary experiments or proof-of-concepts
- Simple clarification questions
- Internal code organization changes — refactoring that doesn't change external behavior (e.g., moving dependencies between aliases, renaming internal variables)
Documentation Structure
Project documentation follows this hierarchy (create only what's needed):
project-root/
├── README.md # Project intro, badges, quick links (minimal)
├── docs/
│ ├── index.md # Main documentation hub
│ ├── functional/ # Functional requirement specifications
│ │ ├── index.md # Requirements overview (links to specs)
│ │ ├── feature-1.md
│ │ └── ...
│ └── technical/ # Technical documentation
│ ├── index.md # Technical docs overview
│ ├── architecture.md # System design (optional)
│ ├── development.md # Dev setup, build, test (optional)
│ ├── operational.md # Deploy, monitor, manage (optional)
│ └── ...component docs...Flexible File vs Directory Structure
Only create documentation that exists. Don't create empty files or directories.
For any topic, start with a single file when content is simple:
docs/technical/architecture.mddocs/technical/development.md
Expand to a directory with index.md when content grows complex:
docs/technical/architecture/index.md+ subtopic filesdocs/technical/development/index.mdlinking to subtopicsdocs/technical/operational/index.md— deployment, monitoring, management
Core Principles
1. No Duplication — Single Source of Truth
- Each piece of information should exist in EXACTLY ONE appropriate place
- Higher-level docs provide summaries and links, NOT duplicate content
- NEVER copy-paste content between documents — use links and references instead
- NEVER duplicate information from source files — especially version numbers, configuration values, or data that lives in code
- Source code documentation is authoritative for function/module docs — technical docs should link to generated API docs rather than duplicate
2. Appropriate Placement
- Functional specs (
docs/functional/*) describe WHAT features do and WHY they exist - Technical docs (
docs/technical/*) describe HOW things are implemented - Index docs (
index.mdfiles) summarize and link, don't duplicate - README.md provides minimal project intro, links to
docs/index.md - When adding content, ask: "What is the MOST SPECIFIC appropriate place for this?"
3. Separation of Concerns
- Functional specs MUST NOT contain implementation details
- Technical docs MAY reference features from functional specs
- Index documents provide structure and navigation, not primary content
4. Hierarchical Linking
README.md→docs/index.md→docs/functional/index.mdanddocs/technical/index.md→ specific docs- Cross-references between functional and technical docs are encouraged
- Links replace duplication — always prefer linking over copying
5. Bidirectional Consistency
- When any document changes, update all documents that reference or are referenced by it
- Propagate changes up and down the documentation hierarchy
6. Source Code is Primary Documentation
- Well-named functions, parameters, and data structures are the first layer of documentation
- Comments explain intent, not what the code does
- For code-level documentation conventions, consult language-specific editing skills
7. Procedural Instructions Hierarchy
- Prefer the most deterministic form: executable scripts/commands > checklists/decision trees > prose
Anti-Duplication Workflow
Before adding ANY documentation content:
1. Check if it already exists elsewhere — search across all docs, determine if you should update that location or link to it 2. Determine the single best location — feature requirements → docs/functional/, implementation details → docs/technical/, dev setup → docs/technical/development.md 3. Use links instead of duplication — write it ONCE in the most appropriate place, other documents link to it 4. Consolidate when you find duplication — identify which location is most appropriate, keep content there, replace duplicates with links
Example:
Bad — same content in index and detail file:
# docs/functional/index.md
## Image Viewer
The image viewer allows users to view images with zoom and pan controls...
[3 paragraphs]Good — single source with linking:
# docs/functional/index.md
## Image Viewer
Interactive image viewing with zoom, pan, and navigation controls.
See [image-viewer.md](image-viewer.md) for detailed requirements.Workflows
When Updating Existing Documentation
1. Identify the document type being modified 2. Determine impact scope — search for documents that link TO and FROM this document 3. Update all affected documents — parent summaries, child details, cross-references 4. Verify consistency — check links, descriptions, separation of concerns
When Creating New Documentation
1. Determine document placement — functional spec → docs/functional/, technical doc → docs/technical/ 2. Create the document with clear filename (kebab-case), appropriate content 3. Update parent documents — add links in relevant index files 4. Create cross-references — link between functional and technical docs
When Reviewing Existing Documentation
1. Audit current state — list all docs, find duplicates, identify misplaced content 2. Plan reorganization — map files to target locations, identify consolidation opportunities 3. Execute reorganization — move/rename files, create index files, update cross-references 4. Clean up content — remove duplication, enforce separation of concerns, condense verbose content 5. Verify conformance — all links valid, no orphaned files, no duplicate content
When Documents Don't Exist
1. Assess what exists — README, docs/ directory, informal documentation 2. Create missing structure (only what's needed) — docs/, docs/functional/, docs/technical/ 3. Generate core documents in order: README.md → docs/index.md → category indexes 4. Populate with initial content from existing code, comments, or informal docs 5. Incrementally add detailed docs as features and implementation docs are needed
Content Guidelines
Link Formatting
**[Feature Name](file.md)** - description
Writing Style: Concise But Clear
- Use bullet points over paragraphs when listing information
- Start with the essential point, add details only if necessary
- Prefer short sentences (10-15 words)
- Cut introductory phrases, marketing language, obvious statements
- Use active voice and direct language
Document Templates
README.md — 1-2 sentences on what the project does + link to docs/index.md
docs/index.md — Overview, quick start, links to functional and technical docs
docs/functional/index.md — Vision (1-2 sentences), features list with one-line descriptions + links
*docs/functional/.md** — Overview, user value, requirements (descriptive names, NO numeric IDs), acceptance criteria, NO implementation details
docs/technical/index.md — Development environment (first), stack, design/architecture, modules, deployment (last)
*docs/technical/.md** — Purpose, key functions, algorithms, code references (file:line)
docs/technical/development.md — Prerequisites, quick start, commands reference, workflows, troubleshooting
For a detailed checklist when reviewing documentation, see references/review-checklist.md.
Examples
Adding a new authentication feature
1. Create functional spec: docs/functional/authentication.md — what auth is needed and why, NO implementation details 2. Update `docs/functional/index.md` — add link and brief description 3. Create technical doc: docs/technical/auth-implementation.md — reference the functional spec, detail technical decisions 4. Update `docs/technical/index.md` — add link
Updating an existing feature spec
1. Make changes to the functional spec 2. Check parent index — update description if summary changed 3. Check technical docs — find docs that reference this spec 4. Update technical docs if requirements change affects implementation 5. Verify `docs/index.md` still accurately describes project scope
Adding development instructions
1. Add to `docs/technical/development.md` — commands, workflows, troubleshooting 2. Update `docs/technical/index.md` — add link if not present 3. Do NOT duplicate — don't copy command definitions from bb.edn, reference source of truth

Functional Requirements
ShopAPI provides a complete e-commerce backend.
Features
- [Product Catalog](product-catalog.md) - Browse, search, and filter products with full-text search powered by PostgreSQL tsvector
- [Shopping Cart](shopping-cart.md) - Persistent cart management with inventory validation
- [Order Processing](order-processing.md) - Order lifecycle from checkout to delivery with async pipeline
Order Processing
Overview
Full order lifecycle from cart checkout to delivery tracking.
Requirements
- Place orders from cart contents
- Order states: pending -> confirmed -> shipped -> delivered
- Track order status and history
- View past orders
- Failed orders are retried up to 3 times before being marked as failed
Pipeline Implementation
Orders are processed asynchronously using core.async:
(defn start-order-pipeline []
(async/pipeline 4
processed-ch
(map process-order)
order-ch))The pipeline uses 4 worker threads. Each order goes through validation, payment processing, and inventory reservation.
Order States
pending- Just placed, awaiting processingconfirmed- Payment verified, inventory reservedshipped- Handed off to fulfillmentdelivered- Received by customerfailed- Processing failed after 3 retries

Order Processing Pipeline
Overview
Orders are processed asynchronously using core.async channels.
Pipeline Architecture
1. Order placed -> message on order-channel 2. process-order consumer validates inventory and payment 3. On success: order confirmed, inventory decremented 4. On failure: retry up to 3 times, then mark as failed
Implementation
(defn start-order-pipeline []
(async/pipeline 4
processed-ch
(map process-order)
order-ch))Uses a fixed thread pool of 4 workers via core.async/pipeline.

Deployment
Building
clojure -T:build uber # Build uberjarThe uberjar is output to target/notesync.jar.
Running in Production
java -jar target/notesync.jarAll configuration is via environment variables (see README.md for the full list).
Docker
FROM eclipse-temurin:21-jre
COPY target/notesync.jar /app/notesync.jar
EXPOSE 3000
CMD ["java", "-jar", "/app/notesync.jar"]Database Migrations
Run before each deploy:
clojure -M:migrateMigrations are in resources/migrations/ and use a sequential numbering scheme.
Health Check
GET /health returns 200 OK with {"status": "ok"} when the server is running and connected to both PostgreSQL and Redis.
Notes & Notebooks
Notes
Users can create, edit, and organize notes. Notes support Markdown formatting and can be tagged for searching.
Requirements
- Create notes with title, body (Markdown), and optional tags
- Edit note title, body, and tags
- Delete notes (soft delete with 30-day recovery)
- List all notes with pagination and sorting (by date, title)
- Filter notes by tag, notebook, or date range
Note Storage
Notes are stored in the notes table:
CREATE TABLE notes (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
user_id UUID REFERENCES users(id),
notebook_id UUID REFERENCES notebooks(id),
title TEXT NOT NULL,
body TEXT NOT NULL DEFAULT '',
tags TEXT[] DEFAULT '{}',
search_vector tsvector,
deleted_at TIMESTAMPTZ,
created_at TIMESTAMPTZ DEFAULT now(),
updated_at TIMESTAMPTZ DEFAULT now()
);
CREATE TRIGGER notes_search_update
BEFORE INSERT OR UPDATE ON notes
FOR EACH ROW EXECUTE FUNCTION
tsvector_update_trigger(search_vector, 'pg_catalog.english', title, body);Notebooks
Notes are grouped into notebooks for organization.
Requirements
- Create notebooks with a name
- Rename notebooks
- Delete notebooks (moves notes to "Unfiled" notebook)
- Each user has a default "Unfiled" notebook created on registration
- List notebooks with note count
Implementation
Notebooks use a simple CRUD pattern in notesync.notebooks:
(defn create-notebook [user-id name]
(db/execute-one! ["INSERT INTO notebooks (user_id, name) VALUES (?, ?)"
user-id name]))
(defn delete-notebook [user-id notebook-id]
(jdbc/with-transaction [tx (db/ds)]
;; Move notes to Unfiled
(jdbc/execute! tx ["UPDATE notes SET notebook_id = (SELECT id FROM notebooks WHERE user_id = ? AND name = 'Unfiled') WHERE notebook_id = ?" user-id notebook-id])
;; Delete the notebook
(jdbc/execute! tx ["DELETE FROM notebooks WHERE id = ? AND user_id = ?" notebook-id user-id])))Search
Full-text search across all user-accessible notes (owned + shared).
Requirements
- Search by keyword across note title and body
- Results ranked by relevance and recency
- Only returns notes the user owns or has been shared
- Pagination support
Implementation
Search uses PostgreSQL's built-in full-text search with tsvector:
(defn search-notes [user-id query & {:keys [limit offset] :or {limit 20 offset 0}}]
(db/execute!
["SELECT n.id, n.title, ts_headline('english', n.body, plainto_tsquery('english', ?)) as snippet,
ts_rank(n.search_vector, plainto_tsquery('english', ?)) as rank
FROM notes n
LEFT JOIN note_shares ns ON ns.note_id = n.id AND ns.user_id = ?
WHERE (n.user_id = ? OR ns.user_id IS NOT NULL)
AND n.deleted_at IS NULL
AND n.search_vector @@ plainto_tsquery('english', ?)
ORDER BY rank DESC, n.updated_at DESC
LIMIT ? OFFSET ?"
query query user-id user-id query limit offset]))The search_vector column is automatically maintained by a trigger (see notes-and-notebooks.md).
Sharing & Collaboration
Overview
Notes and notebooks can be shared with other users for collaborative editing. Changes to shared notes are synchronized in real time via WebSocket connections backed by Redis pub/sub.
Requirements
- Share a note with another user by email
- Set permission level: read-only or read-write
- Revoke sharing access
- Note owner can see all collaborators
- Shared notes appear in the recipient's "Shared with me" view
- Real-time sync: when a collaborator edits a shared note, all other viewers see changes immediately
Real-Time Sync Architecture
Client A (edit) → WebSocket → Server → Redis pub/sub → Server → WebSocket → Client B (update)The sync module (notesync.sync) manages connections and message routing:
(defn on-note-edit [note-id user-id patch]
;; Broadcast edit to all other viewers of this note
(let [msg {:type :edit
:note-id note-id
:user-id user-id
:patch patch
:timestamp (System/currentTimeMillis)}]
(redis/publish (str "note:" note-id) (pr-str msg))))Each WebSocket connection subscribes to the Redis channel for the note being viewed. When an edit comes in, it's broadcast to all subscribers except the sender.
Access Control
Sharing is tracked in the note_shares table:
CREATE TABLE note_shares (
note_id UUID REFERENCES notes(id),
user_id UUID REFERENCES users(id),
permission VARCHAR(10) CHECK (permission IN ('read', 'write')),
created_at TIMESTAMPTZ DEFAULT now(),
PRIMARY KEY (note_id, user_id)
);The notesync.sharing namespace checks permissions before allowing reads or writes on shared notes.
Acceptance Criteria
- Sharing a note sends no notification (future feature)
- Revoking access immediately disconnects the user's WebSocket for that note
- A user with read-only access cannot edit via the API or WebSocket
- Deleting a shared note revokes all shares
NoteSync
A collaborative note-taking API with real-time sync, built with Clojure.
Tech Stack
- Clojure 1.12 with Ring and Reitit
- PostgreSQL 16 with next.jdbc
- Redis for pub/sub real-time sync
- buddy-auth for JWT authentication
Getting Started

| Variable | Default | Description |
|---|---|---|
| PORT | 3000 | HTTP server port |

Features
Notes
Users can create, edit, and organize notes into notebooks. Notes support Markdown formatting and can be tagged for easy searching.
Notebooks
Notes are grouped into notebooks. Users can create, rename, and delete notebooks. Deleting a notebook moves its notes to "Unfiled."
Sharing & Collaboration
Notes and notebooks can be shared with other users. Shared notes support real-time collaborative editing — changes are broadcast to all viewers via Redis pub/sub.
Search
Full-text search across all notes using PostgreSQL tsvector. Results are ranked by relevance and recency.
API Endpoints
Authentication
POST /api/auth/register— Create accountPOST /api/auth/login— Get JWT tokenPOST /api/auth/refresh— Refresh token

Documentation Review Checklist
Use this checklist when reviewing or auditing existing documentation.
Directory Structure (Required)
- [ ] Use exact directory names —
docs/functional/anddocs/technical/are requirements, not suggestions - [ ] Rename non-conforming directories — flag and fix during audit
Hierarchy Violations
- [ ] README.md vs docs/index.md — README should be minimal (description + link only), no duplicated quick start or examples
- [ ] docs/index.md links — Should only link to top-level sections (functional/index.md, technical/index.md), not their children
- [ ] Development content — Must live in docs/technical/development.md, not in docs/index.md or README
- [ ] API docs link — Belongs in docs/technical/index.md, not docs/index.md
Content Placement
- [ ] Quick start — Lives in ONE place only (docs/index.md), not also in README
- [ ] Build commands — Live in docs/technical/development.md only
- [ ] Feature details — Live in docs/functional/*.md, not in index files
- [ ] Implementation details — Live in docs/technical/*.md, not in functional specs
Index File Rules
- [ ] docs/index.md — Contains: overview, quick start, links to functional/ and technical/ indexes only
- [ ] docs/functional/index.md — Contains: vision, feature list with one-line descriptions + links to specs
- [ ] docs/technical/index.md — Contains: stack, module list, links to development.md, API docs, and component docs
Cross-Document Duplication
- [ ] No repeated code examples — Same example should not appear in multiple files
- [ ] No repeated explanations — Concepts explained once, linked elsewhere
- [ ] Version/config values — Never duplicated from source files into docs
Content Quality
- [ ] No duplication — Each piece of info in exactly one place
- [ ] Concise and clear — No filler, short sentences, bullet points over paragraphs
- [ ] Appropriate location — Follows placement guidelines
- [ ] Links valid — All links point to existing files/sections
- [ ] Functional specs clean — No implementation details
- [ ] Terminology consistent — Same terms used across all docs
- [ ] Index docs summarize and link — Don't duplicate child doc content
