Guidance for human and AI contributors working in this repository.

1. Purpose

Paperclip is a control plane for AI-agent companies. The current implementation target is V1 and is defined in doc/SPEC-implementation.md.

2. Read This First

Before making changes, read in this order:

1. doc/GOAL.md
2. doc/PRODUCT.md
3. doc/SPEC-implementation.md
4. doc/DEVELOPING.md
5. doc/DATABASE.md

doc/SPEC.md is long-horizon product context. doc/SPEC-implementation.md is the concrete V1 build contract.

3. Repo Map

• server/: Express REST API and orchestration services
• ui/: React + Vite board UI
• packages/db/: Drizzle schema, migrations, DB clients
• packages/shared/: shared types, constants, validators, API path constants
• packages/adapters/: agent adapter implementations (Claude, Codex, Cursor, etc.)
• packages/adapter-utils/: shared adapter utilities
• packages/plugins/: plugin system packages
• doc/: operational and product docs

4. Dev Setup (Auto DB)

Use embedded PGlite in dev by leaving DATABASE_URL unset.

pnpm install
pnpm dev

This starts:

• API: http://localhost:3100
• UI: http://localhost:3100 (served by API server in dev middleware mode)

Quick checks:

curl http://localhost:3100/api/health
curl http://localhost:3100/api/companies

Reset local dev DB:

rm -rf data/pglite
pnpm dev

5. Core Engineering Rules

1. Keep changes company-scoped. Every domain entity should be scoped to a company and company boundaries must be enforced in routes/services.

2. Keep contracts synchronized. If you change schema/API behavior, update all impacted layers:

• packages/db schema and exports
• packages/shared types/constants/validators
• server routes/services
• ui API clients and pages

3. Preserve control-plane invariants.

• Single-assignee task model
• Atomic issue checkout semantics
• Approval gates for governed actions
• Budget hard-stop auto-pause behavior
• Activity logging for mutating actions

4. Do not replace strategic docs wholesale unless asked. Prefer additive updates. Keep doc/SPEC.md and doc/SPEC-implementation.md aligned.

5. Keep repo plan docs dated and centralized. When you are creating a plan file in the repository itself, new plan documents belong in doc/plans/ and should use YYYY-MM-DD-slug.md filenames. This does not replace Paperclip issue planning: if a Paperclip issue asks for a plan, update the issue plan document per the paperclip skill instead of creating a repo markdown file.

6. Database Change Workflow

When changing data model:

1. Edit packages/db/src/schema/*.ts
2. Ensure new tables are exported from packages/db/src/schema/index.ts
3. Generate migration:

pnpm db:generate

4. Validate compile:

pnpm -r typecheck

Notes:

• packages/db/drizzle.config.ts reads compiled schema from dist/schema/*.js
• pnpm db:generate compiles packages/db first

7. Verification Before Hand-off

Run this full check before claiming done:

pnpm -r typecheck
pnpm test:run
pnpm build

If anything cannot be run, explicitly report what was not run and why.

8. API and Auth Expectations

• Base path: /api
• Board access is treated as full-control operator context
• Agent access uses bearer API keys (agent_api_keys), hashed at rest
• Agent keys must not access other companies

When adding endpoints:

• apply company access checks
• enforce actor permissions (board vs agent)
• write activity log entries for mutations
• return consistent HTTP errors (400/401/403/404/409/422/500)

9. UI Expectations

• Keep routes and nav aligned with available API surface
• Use company selection context for company-scoped pages
• Surface failures clearly; do not silently ignore API errors

10. Pull Request Requirements

When creating a pull request (via gh pr create or any other method), you must read and fill in every section of .github/PULL_REQUEST_TEMPLATE.md. Do not craft ad-hoc PR bodies — use the template as the structure for your PR description. Required sections:

• Thinking Path — trace reasoning from project context to this change (see CONTRIBUTING.md for examples)
• What Changed — bullet list of concrete changes
• Verification — how a reviewer can confirm it works
• Risks — what could go wrong
• Model Used — the AI model that produced or assisted with the change (provider, exact model ID, context window, capabilities). Write "None — human-authored" if no AI was used.
• Checklist — all items checked

11. Definition of Done

A change is done when all are true:

1. Behavior matches doc/SPEC-implementation.md
2. Typecheck, tests, and build pass
3. Contracts are synced across db/shared/server/ui
4. Docs updated when behavior or commands change
5. PR description follows the PR template with all sections filled in (including Model Used)

11. Fork-Specific: HenkDz/paperclip

This is a fork of paperclipai/paperclip with QoL patches and an external-only Hermes adapter story on branch feat/externalize-hermes-adapter (tree).

Branch Strategy

• feat/externalize-hermes-adapter → core has no hermes-paperclip-adapter dependency and no built-in hermes_local registration. Install Hermes via the Adapter Plugin manager (@henkey/hermes-paperclip-adapter or a file: path).
• Older fork branches may still document built-in Hermes; treat this file as authoritative for the externalize branch.

Hermes (plugin only)

• Register through Board → Adapter manager (same as Droid). Type remains hermes_local once the package is loaded.
• UI uses generic config-schema + ui-parser.js from the package — no Hermes imports in server/ or ui/ source.
• Optional: file: entry in ~/.paperclip/adapter-plugins.json for local dev of the adapter repo.

Local Dev

• Fork runs on port 3101+ (auto-detects if 3100 is taken by upstream instance)
• npx vite build hangs on NTFS — use node node_modules/vite/bin/vite.js build instead
• Server startup from NTFS takes 30-60s — don't assume failure immediately
• Kill ALL paperclip processes before starting: pkill -f "paperclip"; pkill -f "tsx.*index.ts"
• Vite cache survives rm -rf dist — delete both: rm -rf ui/dist ui/node_modules/.vite

Fork QoL Patches (not in upstream)

These are local modifications in the fork's UI. If re-copying source, these must be re-applied:

1. stderr_group — amber accordion for MCP init noise in RunTranscriptView.tsx
2. tool_group — accordion for consecutive non-terminal tools (write, read, search, browser)
3. Dashboard excerpt — LatestRunCard strips markdown, shows first 3 lines/280 chars

Plugin System

PR #2218 (feat/external-adapter-phase1) adds external adapter support. See root AGENTS.md for full details.

• Adapters can be loaded as external plugins via ~/.paperclip/adapter-plugins.json
• The plugin-loader should have ZERO hardcoded adapter imports — pure dynamic loading
• createServerAdapter() must include ALL optional fields (especially detectModel)
• Built-in UI adapters can shadow external plugin parsers — remove built-in when fully externalizing
• Reference external adapters: Hermes (@henkey/hermes-paperclip-adapter or file:) and Droid (npm)
