+
+Unified Developer Experience Platform for the [Pachca API](https://dev.pachca.com) — the REST API of Pachca, a corporate messenger. A single source (TypeSpec + workflows.ts + examples.ts) generates artifacts for every channel: web docs, CLI, SDKs, an n8n node, agent skills, and LLM context.
+
+**Docs**: https://dev.pachca.com · **OpenAPI**: https://dev.pachca.com/openapi.yaml · **Authorization**: https://dev.pachca.com/api/authorization · **Changelog**: https://dev.pachca.com/updates · **Postman/Bruno**: https://dev.pachca.com/pachca.postman_collection.json
+
+## CLI
+
+```bash
+# Zero-install (npx)
+npx @pachca/cli messages create --entity-id=123 --content="Hello!" --token $PACHCA_TOKEN
+
+# For regular use
+npm install -g @pachca/cli
+pachca auth login
+pachca messages create --entity-id=123 --content="Hello!"
+pachca guide "send a message"  # CLI guide
+
+# Built-in API reference right in the terminal (for agents)
+pachca api ls                          # list every endpoint
+pachca api POST /messages --describe   # params, body, example
+pachca api POST /messages -f message[content]="Hello"  # direct request
+```
+
+Every API method is available as a command: typed flags, validation, four output formats (table, JSON, YAML, CSV), cursor pagination, multiple auth profiles, and a non-interactive mode for CI and AI agents. The `pachca api` command sends direct requests to any method and ships a built-in API reference (`ls`, `--describe`, `--spec`, `--docs`) from the same OpenAPI spec — an agent never needs to open the docs website.
+
+**Docs**: https://dev.pachca.com/guides/cli
+
+## Agent Skills
+
+AI agents use CLI-first skills with step-by-step workflows, zero-friction authorization, and automatic permission checks.
+
+### Install (40+ agents)
+
+```bash
+npx skills add pachca/openapi
+```
+
+### Compatibility
+
+| Agent | Path |
+|-------|------|
+| Claude Code | `CLAUDE.md` → `AGENTS.md` |
+| Codex CLI | `AGENTS.md` |
+| OpenCode | `skills/` |
+| Cursor, Windsurf, Continue, 40+ more | Auto-detected |
+| Manual install | `cp -r skills/pachca-* <path>` |
+
+### Available skills
+
+| Skill | Description |
+|-------|-------------|
+| `pachca-profile` | Profile, status, custom fields |
+| `pachca-users` | Employees and tags (groups) |
+| `pachca-chats` | Channels, conversations, members, export |
+| `pachca-messages` | Messages, files, reactions, buttons |
+| `pachca-bots` | Bots, webhooks, unfurling |
+| `pachca-forms` | Interactive forms |
+| `pachca-tasks` | Reminders (tasks) |
+| `pachca-search` | Full-text search |
+| `pachca-security` | Audit events, DLP |
+| `pachca` | Router skill — routes to the right skill |
+
+Skills are generated automatically from the OpenAPI spec on `bun turbo build`. Install only from the official repository — skills contain instructions only (no executable code).
+
+## n8n
+
+A community node for [n8n](https://n8n.io/) — 18 resources, 65+ operations, and a Pachca Trigger with automatic webhook registration.
+
+```bash
+# In n8n: Settings > Community Nodes > n8n-nodes-pachca
+npm install n8n-nodes-pachca
+```
+
+Generated automatically from the OpenAPI spec, fully backward-compatible with v1.

+
+## SDK
+
+| Language | Package | Registry |
+|----------|---------|----------|
+| [TypeScript](sdk/typescript/README.md) | `@pachca/sdk` | npm |
+| [Python](sdk/python/generated/README.md) | `pachca-sdk` | PyPI |
+| [Go](sdk/go/README.md) | `github.com/pachca/go-sdk` | Go modules |
+| [Kotlin](sdk/kotlin/README.md) | `com.pachca:sdk` | JitPack |
+| [Swift](sdk/swift/README.md) | `PachcaSDK` | SPM |
+| [C#](sdk/csharp/generated/README.md) | `Pachca.Sdk` | NuGet |
+
+Every SDK follows one pattern: `PachcaClient(token)` → `client.service.method(request)`.
+
+**Conventions:**
+- **Input**: path params and body fields (if ≤2) are spread into method arguments. Otherwise — a single request object.
+- **Output**: if an API response contains a single `data` field, the SDK returns its contents directly.
+- Service, method, and field names match the operationId and parameters from the OpenAPI spec.
+
+**Example (TypeScript):**
+
+```typescript
+import { PachcaClient } from "@pachca/sdk";
+
+const pachca = new PachcaClient("YOUR_TOKEN");
+const users = await pachca.users.listUsers();
+await pachca.reactions.addReaction(messageId, { code: "👍" }); // ≤2 fields → arguments
+```
+
+SDKs are generated from `openapi.yaml` and published automatically on push to `main`.
+
+### Generator
+
+Instead of a prebuilt SDK, you can generate a typed client straight into your own project:
+
+```bash
+npx @pachca/generator --output ./generated --lang typescript
+npx @pachca/generator --output ./generated --lang typescript,python,go,kotlin,swift,csharp
+```
+
+| Option | Description |
+|--------|-------------|
+| `--spec <path\|url>` | Path or URL to an OpenAPI 3.0 YAML (default: `https://dev.pachca.com/openapi.yaml`) |
+| `--output <dir>` | Output directory for the generated code |
+| `--lang <langs>` | Comma-separated languages: `typescript`, `python`, `go`, `kotlin`, `swift`, `csharp` |
+| `--examples` | Generate `examples.json` with call examples |
+
+**Docs**: https://dev.pachca.com/guides/sdk/overview
+
+## Testing
+
+| Tool | How to use |
+|------|------------|
+| [Scalar](https://client.scalar.com/?url=https://dev.pachca.com/openapi.yaml) | Online client right in the browser — no install |
+| [Postman Collection](https://dev.pachca.com/pachca.postman_collection.json) | Download and import into Postman |
+| Bruno | Download the same file and import: File → Import → Postman Collection |
+
+## AI integrations
+
+| File | Contents |
+|------|----------|
+| [`/llms.txt`](https://dev.pachca.com/llms.txt) | Short index: every endpoint with links + a line map |
+| [`/llms-full.txt`](https://dev.pachca.com/llms-full.txt) | Full docs: guides + endpoints with parameters |
+| [`/llms-en.txt`](https://dev.pachca.com/llms-en.txt) | English version of the full docs (for Context7) |

+| [`/workflows.arazzo.yaml`](https://dev.pachca.com/workflows.arazzo.yaml) | Multi-step API workflows in Arazzo 1.0.1 |

+| `<any page>.md` | Markdown version of any page (or the `Accept: text/markdown` header) |
+| `/.well-known/agent-skills/index.json` | Agent Skills discovery index (Cloudflare RFC) |
+
+[Context7](https://context7.com/pachca/openapi) — AI-native document discovery. Through the CLI, the API reference is available without the website too: `pachca api ls`, `pachca api <METHOD> <path> --describe`.
+
+All files are served with `Access-Control-Allow-Origin: *`, marked `X-Robots-Tag: noindex`, and cached through a CDN.
