+# AGENTS.md
+
+You are working in the iii monorepo — a backend unification engine with three primitives: **Function**, **Trigger**, **Worker**. The engine is Rust. SDKs exist for TypeScript, Python, and Rust. All communicate over WebSocket.
+
+## Commands
+
+```bash
+# Setup
+pnpm install                     # JS/TS dependencies
+cargo build --release            # Rust workspace
+
+# Build
+pnpm build                       # all JS/TS packages (Turborepo)
+cargo build --release             # engine + Rust SDK + console
+
+# Test
+pnpm test                        # all JS/TS tests
+cargo test                       # all Rust tests
+cargo test -p iii-engine          # engine only
+cargo test -p iii-sdk             # Rust SDK only
+cd sdk/packages/python/iii && uv sync --extra dev && uv run pytest  # Python SDK
+
+# Lint & Format
+pnpm fmt                         # format JS/TS (Biome)
+pnpm fmt:check                   # check without changes
+pnpm lint                        # lint JS/TS
+cargo fmt --all                   # format Rust
+cargo clippy --workspace          # lint Rust
+
+# Run
+cargo run --release               # start engine (reads engine/config.yaml)
+pnpm dev:console                  # console frontend dev server
+pnpm dev:docs                     # docs dev server (Mintlify)

+
+**Workspaces:** `Cargo.toml` (Rust), `pnpm-workspace.yaml` (JS/TS), `turbo.json` (build orchestration).
+
+## Boundaries
+
+### Always
+
+- Use `pnpm` (never `npm`) for JS/TS packages
+- Use `cargo fmt --all` before committing Rust changes
+- Use `pnpm fmt` before committing JS/TS changes
+- Use leading slashes for HTTP `api_path` values: `/orders`, `/users/:id`
+- Use `expression` (not `cron`) for cron trigger config fields
+- Use `::` separator for function IDs: `orders::validate`, `reports::daily-summary`
+- Use `workspace:*` for internal pnpm package references
+- Include `## When to Use` and `## Boundaries` sections in every SKILL.md
+- Match SKILL.md `name` field to its directory name exactly
+
+### Ask First
+
+- Changes to public SDK APIs (npm/PyPI/crates.io surface)
+- Changes to engine config schema (`engine/config.yaml`)
+- Changes to CI/CD workflows (`.github/`)
+- Adding new engine modules
+- Modifying the WebSocket protocol between SDK and engine
+
+### Never
+
+- Commit secrets, API keys, or credentials
+- Use `npm` instead of `pnpm`
+- Push directly to `main`
+- Change engine licensing (ELv2) or SDK licensing (Apache-2.0)
+- Remove "When to Use" / "Boundaries" from SKILL.md files (SkillKit validates these)
+- Use `cron` as a config key — the engine uses `expression`
+- Omit leading slashes on `api_path` — the engine standard is `/path`
+
+## Code Style
+
+**Rust (engine + SDK):**
+```rust
+// Function IDs use :: separator
+iii.register_function(
+    RegisterFunction::new("orders::validate", validate_order)
+        .description("Validate an incoming order"),
+);
+
+// HTTP triggers use leading slash
+iii.register_trigger(
+    IIITrigger::Http(HttpTriggerConfig::new("/orders/validate").method(HttpMethod::Post))
+        .for_function("orders::validate"),
+);
+
+// Cron triggers use `expression` field (7-field: sec min hour dom month dow year)
+iii.register_trigger(
+    IIITrigger::Cron(CronTriggerConfig::new("0 0 9 * * * *"))
+        .for_function("reports::daily-summary"),
+);
+```
+
+**TypeScript (SDK):**
+```typescript
+// HTTP trigger with leading slash
+iii.registerTrigger({
+  type: 'http',
+  function_id: 'orders::validate',
+  config: { api_path: '/orders/validate', http_method: 'POST' },
+});
+
+// Cron trigger with `expression` (not `cron`)
+iii.registerTrigger({
+  type: 'cron',
+  function_id: 'reports::daily-summary',
+  config: { expression: '0 0 9 * * * *' },
+});
+```
+
+**Python (SDK):**
+```python
+# Same patterns — leading slash, expression field
+iii.register_trigger({
+    "type": "http",
+    "function_id": "orders::validate",
+    "config": {"api_path": "/orders/validate", "http_method": "POST"},
+})
+```
+
+## Skills
+
+The `skills/` directory contains 24 agent skills (iii-prefixed) auto-discovered by `npx skills add iii-hq/iii` and `npx skillkit install iii-hq/iii`. Reference implementations live in `skills/references/` with TypeScript, Python, and Rust variants.

+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding any notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the

+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
