+name: add-api-resource
+description: Add or update public v1/v2 API resources, verbs, and flags in fintoc-cli. Also use to assess whether new API fields or a fintoc SDK bump require CLI changes.
+---
+
+# Add or update an API resource
+
+## CLI model
+
+Every resource is one `ResourceDef` entry in `src/resources/registry.ts`. `src/resources/factory.ts` turns it into `fintoc [v2] <resource> <verb>` commands that call the `fintoc` node SDK. The CLI only calls the published SDK, so a resource or verb can only be added once the SDK has it.
+
+Check the SDK first. Look for the manager in `node_modules/fintoc/build/main/lib/core.d.ts` (`Fintoc` is v1, `FintocV2` is v2), or in its parent manager's `.js` if it is nested, and for its verbs in `XManager.methods = [...]` inside the manager's `.js`. If the manager or a verb you need is missing, run `npm install fintoc@latest`. If it is still missing, stop: it needs a fintoc-node release first.
+
+## Choose the scope
+
+| Change | Implementation |
+| --- | --- |
+| New resource | Append a registry entry at the end of the array. Copy `account_numbers` (v2, create and delete). |
+| New verb | Add it to the entry's `verbs`, with its flags when it takes any. |
+| New flag or filter | Add it to the verb's flags (`createFlags`, `listFlags`, `getFlags`, `testFlags`). |
+| Nested resource | Use a dotted `sdkMethod`. Copy `movements`. |
+| New field | Usually no change, since `get` and `--json` show every field. Add a flag only for a new create param or list filter, and touch `priorityColumns` only if the field matters in `list`. |
+
+Do not rename or remove existing flags or verbs, since users' scripts depend on them.
+
+## Registry entry
+
+| Field | Rule |
+| --- | --- |
+| `name`, `cliCommand` | snake_case plural API name (`account_numbers`) |
+| `displayName` | Singular, human readable (`account number`) |
+| `sdkNamespace` | `'v1'` for `Fintoc`, `'v2'` for `FintocV2` |
+| `sdkMethod` | camelCase manager property (`accountNumbers`). Nested managers use a dotted path (`accounts.movements`) |
+| `verbs` | Only the ones in the manager's `methods`, out of `create`, `get`, `list`, `delete`, `expire`, `test` |
+| `needsJws` | `true` when the API requires a JWS signature to create |
+| `priorityColumns` | 1 to 6 fields for `list`, usually `id` first |
+| `createFlags` | Must be non-empty when there is `create` |
+| `getArg` | Only when `get` takes something other than an id (see `links`) |
+
+Flags: `name` is kebab-case and is sent as snake_case, so it must match the API param. Use `nestedPath` for fields inside an object (`counterparty.account_number`). Set `required: true` only if the API requires it. For enum filters like `status`, link the object docs with a `DOCS_*_URL` constant from `src/lib/constants.ts` instead of listing values.
+
+Watch out for:
+
+- Nested managers only work for `get` and `list`. Limit `verbs` to those two and add the parent id as a required flag to each verb's flags (`getFlags`, `listFlags`), matching the SDK placeholder (`account-id` → `{account_id}`).
+- A flag segment that starts with a digit (`address-line-1`) breaks the flag. Use a letter-only name and put the API param in `nestedPath` (`address_line_1`).
+- The help text pluralizes with `${displayName}s`, so an irregular plural (`entity` → "entitys") reads wrong. Keep it and mention it in the PR.
+- Anything the factory does not support (an `update` verb, new flag types) stays out. Changing the factory needs its own design and review, so mention it in the PR instead.
+
+## Tests
+
+In `src/resources/__tests__/registry.test.ts`:
+
+- Update the hardcoded counts and name lists in `schema validation` and `v2 resources`. A new v2 resource also goes in the `v2Names` set.
+- Add a test under `resource-specific flags` for required flags, JWS or a dotted `sdkMethod`.
+- If the `name` already exists in the other namespace, look entries up by `name` and `sdkNamespace`, and make the `v2Names` check compare both, so the v1 entry stays covered.
+
+Some tests run against the compiled `dist/`, so build before running them. Then check the generated help:
+
+```sh
+npm run lint && npm run typecheck && npm run build && npm run test
+node dist/index.js [v2] <resource> <verb> --help
+```
+
+## Documentation and PR
+
+Add or update the row in the Resources table in `README.md`, with v1 rows before v2 rows.
+
+Follow the repository's PR template and mention the SDK bump and anything left out. Keep CLI version bumps and releases separate from resource changes.

+# Fintoc CLI
+
+## Project
+- Node.js CLI tool, ESM (`"type": "module"`)
+- TypeScript, bundled with tsup to `dist/index.js`
+- Runtime deps: commander, fintoc, smol-toml, @inquirer/prompts, es-toolkit, ws, zod
+
+## Commands
+- `npm run build` — build to dist/
+- `npm run test` — run tests (requires build first)
+- `npm run lint` — ESLint + Prettier check
+- `npm run lint:fix` — auto-fix lint + format
+- `npm run typecheck` — type-check without emitting
+
+## Structure
+- `src/index.ts` — entry point, Commander setup
+- `src/commands/` — one file per command
+- `src/resources/` — resource registry + command factory
+- `src/lib/` — shared utilities (auth, config, output, errors)
+- `src/types.ts` — shared type definitions
+- `src/**/__tests__/` — Vitest tests, colocated with source files
+- `.agents/skills/` — agent skills, shared by Codex and Claude Code (`.claude/skills` links here)
+
+## Conventions
+- ESLint config uses `@antfu/eslint-config` (same as dashboard)
+- Prettier runs as ESLint rule (no separate .prettierrc)
+- No semicolons, single quotes, printWidth 100
+- `no-console: error` — use proper output utilities instead
