# Penut Agent Manual Version: 2026-05-30T02:08:31.419Z Penut is a growth platform. As an AI agent, you drive it on behalf of the user via the `penut` CLI. You propose actions; the user reviews and approves; the platform executes. ## Install and Authenticate If `penut` isn't installed: ```bash /bin/bash -c "$(curl -fsSL https://penut.ai/install)" ``` Authenticate with the setup code from the user's message: ```bash penut auth login --code penut auth status ``` ## Command Grammar The `penut` CLI uses a deterministic token-count grammar. Counting only command tokens (flags and values such as `URL`, `KEY`, `` do not count): | Tokens | Category | Shape | Example | | ------ | ------------------------------------------- | -------------------------------------------------------- | ----------------------------------------------------------------- | | **1** | Global meta | `penut ` | `penut version`, `penut update` | | **2** | CLI built-in (local/meta, not a server op) | `penut ` | `penut auth login`, `penut registry list`, `penut session switch` | | **3** | Registry op — foundation / native / support | `penut ` | `penut billing account status` | | **4** | Registry op — integration / provider | `penut integrations\|providers ` | `penut integrations x posts create --connection ` | ### Determinism rules - **1 token = meta**, always (a registry op is never 1 token). - **2 tokens = built-in**, from a fixed reserved list of areas. - **3 tokens = foundation op** — the first token is a non-namespaced service and is never an integration/provider name. - **4 tokens = integration/provider op** — the first token is literally `integrations` or `providers`; the second is the connection/provider name. - **Multi-word resources are a single token with underscores** and never split (e.g. `identity api_keys create`, `db sql_transaction begin`). This protects the bijection. - **Colon form (`x:posts:create`) is an op-key identifier** used in the registry, scopes, and docs. It is NOT a CLI invocation style. - **Integration/provider ops always use 4 tokens.** The bare 3-token shorthand (`penut x posts create`) is not valid. Use `penut integrations x posts create`. - **`--connection ` is required** for all tier-4 integration ops. - **Action verbs are exact and un-normalized.** Use the exact action segment from the op key (discover via `penut registry op `). The CLI does not rewrite or alias verbs — `db sql query` stays `query`, `identity orgs show` stays `show`. Common actions include `create`, `read`, `list`, `update`, `archive`, `query`, `show`, `status`, `write`, `execute`, `commit`, `drop`, `deploy`, `approve`, `reject`, `retry`, `submit`, `publish`, `remove`, `refresh`, and many more. When in doubt, read the op key. ### Reserved built-in roots These token-1 / token-2 roots are reserved and will never route to a registry op: `help`, `version`, `update`, `config`, `auth`, `session`, `registry`, `recipes`, `changelog`. ### Built-in commands **Tier 1 (meta):** `penut version`, `penut update` **Tier 2 (platform built-ins):** - `penut auth login --code `, `penut auth status`, `penut auth logout` - `penut session switch ` - `penut registry list [--category CATEGORY] [--name SERVICE]`, `penut registry op `, `penut registry openapi` - `penut recipes list|show|search` - `penut changelog list [--since DATE] [--type TYPE]` Everything else is a registry op (tier 3 or 4). ## Response Shapes The raw HTTP API returns one of these shapes. When using the CLI, the output is always JSON and wraps the result in `{ operation, idempotencyKey, result }`. ### Success ```json { "ok": true, ...data } ``` ### Approval Required Some operations require human review. The API returns HTTP 202: ```json { "ok": false, "status": 202, "error": { "stage": "gateway_hook", "code": "APPROVAL_REQUIRED", "message": "Gateway policy requires human approval before this operation runs.", "suggestion": "Approve the generated request from Console or an approval deep link." }, "approval": { "id": "", "kind": "integrations.x.posts.create", "status": "pending" } } ``` ### Error Generic errors return HTTP 4xx/5xx with: ```json { "status": "error", "code": "snake_case_code", "message": "Human-readable explanation", "suggestion": "Action the user should take", "retryable": false, "details": {} } ``` Gateway hook errors return a different shape (nested `error` object, top-level `ok: false`). Check for `error.stage === "gateway_hook"` to identify them. ### Agent Loop 1. Call op. 2. `result.ok === true` → done. 3. `result.ok === false` and `result.status === 202` and `result.error.code === "APPROVAL_REQUIRED"` → surface `result.approval.id` to the user, exit. 4. `result.status === "error"` and `result.retryable === true` → follow `suggestion`, retry once. 5. Otherwise → surface error with `suggestion` to the user. ## Approval Lifecycle Some operations trigger a gateway "approval required" response. The server creates an `ApprovalRequest` (with one `ApprovalAction` inside) and returns the approval ID. Approvals are reviewed in the Console at the approvals inbox. ### Single Action (default) When an op triggers approval, the agent surfaces the approval ID to the user. The user visits the Console approvals page, reviews, and approves/rejects. The action executes after approval. ### Multi-Action Batch For related actions that should be reviewed together (e.g., cross-posting to X + LinkedIn): ```bash # 1. Create empty draft penut approvals batches create --title "Cross-channel launch" # → { batch: { id: "ba_...", actions: [], status: "draft" } } # 2. Append actions via --batch penut integrations x posts create --batch ba_... --connection --text "Launch!" # → { batchUuid: "ba_...", actionUuid: "act_...", position: 0 } penut integrations linkedin posts create --batch ba_... --connection --text "Launch!" # → { batchUuid: "ba_...", actionUuid: "act_...", position: 1 } # 3. Submit for review penut approvals batches submit --id ba_... # → { batch: { id: "ba_...", status: "pending" } } # Rollback a draft (drop without submitting) penut approvals batches drop --id ba_... # → { ok: true, batchId: "ba_...", status: "dropped" } ``` Use `--batch` without a UUID value to create a new draft and add the first action in one step. Use `--batch ` to append to an existing draft. ### Action Statuses | Status | Meaning | | ----------- | -------------------------------------------------- | | `pending` | Awaiting user decision | | `approved` | User said yes, queued for execution | | `rejected` | User said no — final | | `executing` | Currently running | | `executed` | Ran successfully | | `blocked` | Approved but execution can't proceed (recoverable) | | `failed` | Hit an irrecoverable error — final | | `expired` | TTL hit before decision or resolution | ### Request Statuses | Status | Meaning | | ---------- | ------------------------------------ | | `draft` | Batch being built, not yet submitted | | `pending` | Submitted, awaiting action decisions | | `resolved` | All actions have been decided | | `executed` | All approved actions executed | | `canceled` | Canceled by user | | `expired` | TTL hit before resolution | ### Blocked State — Manual Retry An approved action can hit a recoverable condition (connection revoked, out of credit, provider unavailable). It moves to `blocked` with a `blocked_reason`. The user fixes the underlying issue, then retries: ```bash penut approvals actions retry --id ``` Retry re-executes the same approved action without requiring re-approval. If the condition is fixed → `executed`. If still broken → stays `blocked`. No background retries. Retry is also allowed on `failed` actions. ### Failed State — No Retry Actions hit `failed` for: stale resource reference (deleted UUID), op version skew, op-specific permanent failures (e.g., "tweet violates policy"), scope revoked after approval. ### Update Params ```bash penut approvals actions update --id --params '{"text": "New draft"}' ``` Allowed when the action's request is in `draft` status or the action itself is `pending`. ### Cancel ```bash penut approvals requests cancel --id ``` Sets the request status to `canceled` and all its actions to `rejected`. ## Database and Storage Every project has two independent persistence primitives: a real Postgres schema (DB) and an S3-backed object store (Storage). They are separate ops — DB rows reference storage objects by id, not the other way around. ### DB model - Each project gets its own Postgres schema (`project_`) inside a shared `penut_projects` database. The schema is isolated by role — agents only see their own project's tables. - The agent writes plain SQL. There is no DSL, no ORM layer, and no migration files. DDL statements _are_ the migration. - Schema introspection is free: `penut db schema describe` (optionally `--table `) returns columns, types, nullability, defaults, row counts, and a sample row. `penut db schema dependents --table [--column ]` lists code functions and views that reference that table. ### Read vs write split Two ops, enforced server-side. Use the right one. ```bash # Reads — server wraps the statement in BEGIN READ ONLY ... COMMIT. penut db sql query --sql "SELECT id, email FROM users WHERE created_at > $1 ORDER BY id DESC" --params '["2026-01-01T00:00:00Z"]' # Writes + DDL — one statement per call. For multiple statements, use a transaction. penut db sql execute --sql "INSERT INTO users (email) VALUES ($1) RETURNING id" --params '["alice@example.com"]' ``` - Bind parameters are Postgres-native `$1`/`$2`/… passed as a JSON array via `--params '[...]'`. - Multi-line SQL: use `--sql-file ./path.sql`. - `RETURNING` clauses populate `rows` on the `db sql execute` response. ### Transactions Mirror the approvals batch shape. The server holds the transaction with an inactivity TTL (auto-rollback if abandoned). ```bash penut db sql_transaction create # → { txId: "tx_...", expiresAt: "..." } penut db sql_transaction execute --id tx_... --sql "INSERT INTO orders (...) VALUES ($1)" --params '[...]' penut db sql_transaction execute --id tx_... --sql "UPDATE inventory SET qty = qty - 1 WHERE sku = $1" --params '["abc"]' penut db sql_transaction commit --id tx_... # or penut db sql_transaction drop --id tx_... # explicit rollback ``` Transaction-level approval evaluates the union of all enqueued statements' classifications (see matrix below). ### Approval matrix Approval is driven by the SQL verb plus presence/absence of `WHERE`. When in doubt, the server requires approval. | Approval required | Runs without approval | | ------------------------------------------------- | --------------------------------------------------------- | | `DROP …`, `TRUNCATE` | `CREATE TABLE`, `CREATE INDEX`, `CREATE VIEW` | | `ALTER` that removes / renames / retypes a column | `ALTER TABLE … ADD COLUMN` (nullable, no default rewrite) | | `SET NOT NULL` on an existing column | `INSERT` | | `DELETE` or `UPDATE` **without** `WHERE` | `DELETE … WHERE`, `UPDATE … WHERE` | | `ALTER TYPE … ADD VALUE` on an enum | | ### DDL ordering rule - **Forward-compatible** change (`ADD COLUMN` nullable, `CREATE INDEX`): `ALTER` first, then update consumers. - **Backwards-incompatible** change (`DROP COLUMN`, rename, retype): update consumers (code functions, views) first, then `ALTER`. Use `db schema dependents` to find them. ### Quotas and limits - 30s statement timeout per call. - Naked `SELECT` without `LIMIT` gets a `LIMIT 1000` injected; the response sets `truncated: true` if it kicks in. - Max 10,000 rows returned per call. For larger reads, use `db sql export --format csv|jsonl` (returns a signed URL to an artifact). - For bulk import, use `penut db sql copy --table --columns '["col1","col2"]'` with rows on stdin — never write `INSERT … VALUES` with thousands of rows. ### Type marshalling over the wire | Postgres type | JSON representation | | -------------------------- | ------------------------------------ | | `timestamptz`, `timestamp` | ISO 8601 string | | `uuid` | string | | `bigint`, `numeric` | string (precision-safe; never float) | | `bytea` | base64 string | | `jsonb`, `json` | JSON value as-is | Idempotency: pass `--idempotency-key` to `db sql execute` so an approval retry doesn't double-apply. Defensive `INSERT … ON CONFLICT` is encouraged on writes the agent might retry. ### Best-practice schema defaults The `db schema describe` hints and the DDL validator nudge toward these — follow them unless the scenario disagrees. - `id bigserial PRIMARY KEY` by default. Add `uuid uuid UNIQUE DEFAULT gen_random_uuid()` only when external references matter. - `created_at timestamptz NOT NULL DEFAULT now()` on every table. - Prefer `status text CHECK (status IN (...))` over Postgres `ENUM` (cheaper to evolve). - Hard-delete by default. Add `deleted_at timestamptz` and filter `IS NULL` only when the scenario requires soft-delete. - Index any column you query in `WHERE` / `ORDER BY` hot paths. Index every foreign-key column. - Use `jsonb` for shape-varying nested data; promote frequently-queried fields to real columns. - Always declare a `PRIMARY KEY` or `UNIQUE` on `CREATE TABLE` — the validator rejects tables without one. ### Storage Separate primitive from DB. Use it for files, images, exports — anything that shouldn't live as a row. Every file is referenced by UUID; filename is metadata for display only. Files are transferred via the CLI's `--in`/`--out` flags — one mechanism for every op, every destination. The CLI handles presigned URLs, ETag verification, and confirmation internally. Agents never see upload plumbing. ```bash # Upload one or more files to Penut Storage (one object per file) penut storage objects upload --in content=./q2-report.pdf --title "Q2 report" penut storage objects upload --in content=./assets/ # folder → N objects # Download a storage object to disk penut storage objects download --object obj_4d1 --out content=./q2-report.pdf # Replace an existing object's bytes penut storage objects update --object obj_4d1 --in content=./q2-report-v2.pdf penut storage objects read --id obj_... # metadata + signed GET URL penut storage objects list --kind "image" penut storage objects remove --id obj_... # approval-gated soft-delete; dependents scan ``` **`--in`** sends file(s): `--in =` where `` can be a single file, directory (recurses, preserves structure), or repeated for arrays. **`--out`** receives file(s): `--out =` — scalar writes to a file, array writes to a directory. The op's schema declares which fields are file fields (`x-penut-file` marker) — run `penut registry op ` to discover them. **`--source*`** sends inline UTF-8 text (`--source "str"`, `--source-file ./code.ts`, `--source-stdin`). For binary files, always use `--in` — `--source-file` reads as text and corrupts binary. - Signed URLs are TTL'd and per-object. Large files never transit the API. - Delete is soft-delete (`deletedAt`) with blob retained. Removing an object requires approval; the preview includes a dependents scan of project code. - Project-scoped (like `db`). No reference-counting — delete safety uses approval gating + on-demand dependents scan. - Names are never unique identifiers — the UUID is. Uploading `doc.pdf` twice creates two objects, both displaying "doc.pdf", with different UUIDs. ## Connection Discovery Rule Before using an integration, always list connections: ```bash penut integrations connections list --integration ``` If empty, start the OAuth flow: ```bash penut integrations connections create --integration # Returns { authorizationUrl, state } — surface the URL to the user ``` Always pass `--connection ` on every integration op. The CLI enforces this. ## Common Patterns ### 1. Post to X ```bash penut integrations connections list --integration x penut integrations x posts create --connection --text "Hello world" ``` ### 2. Cross-Post (X + LinkedIn in one batch) ```bash penut approvals batches create --title "Cross-channel launch" penut integrations x posts create --batch ba_... --connection --text "Launch!" penut integrations linkedin posts create --batch ba_... --connection --text "Launch!" penut approvals batches submit --id ba_... ``` ### 3. Deploy a Function and Configure a Trigger ```bash penut code functions deploy --name "my-function" --source-file ./handler.ts penut code functions grant-scope --function --scope "integrations.x.posts.create" penut events triggers create --name "new-order" --event "shopify:order:created" --target ``` ### 4. Create a Table and Read it Back ```bash penut db sql execute --sql "CREATE TABLE users (id bigserial PRIMARY KEY, email text NOT NULL UNIQUE, created_at timestamptz NOT NULL DEFAULT now())" penut db sql execute --sql "INSERT INTO users (email) VALUES ($1) RETURNING id" --params '["alice@example.com"]' penut db sql query --sql "SELECT id, email FROM users ORDER BY created_at DESC LIMIT 50" ``` ### 4b. Upload a File to Storage ```bash penut storage objects upload --in content=./report.pdf --title "Report" penut storage objects list --kind "file" ``` ### 5. Send Email via Gmail ```bash penut integrations connections list --integration gmail penut integrations gmail messages send --connection --to "alice@example.com" --subject "Hello" --body "..." ``` ### 6. Inspect Logs After a Failure ```bash penut logs entries list --trace --since 1h penut logs entries show ``` ## Common Errors Error codes come from two sources: the generic `res.error()` helper and gateway hooks. Check `error.stage` to distinguish them (`"gateway_hook"` vs generic). | Code | Stage | Meaning | Action | | --------------------------- | ------------ | ----------------------------------- | -------------------------------------------------------------------------------------- | | `APPROVAL_REQUIRED` | gateway_hook | Op requires human approval | Surface the approval ID to user | | `no_connection` | generic | Integration not connected | Run `penut integrations connections create --integration ` | | `PROJECT_NOT_FOUND` | gateway_hook | Project resolution failed | Select a valid project | | `PHYSICAL_ADDRESS_REQUIRED` | gateway_hook | Marketing email needs brand address | Store the brand's physical address in the project DB and reference it from the send op | | `CONTENT_POLICY_REJECTED` | gateway_hook | Ad creative failed content scan | Remove policy-risky language | | 401 | generic | Session expired | Re-authenticate | | 403 | generic | Missing scope | Request scope grant | | 404 | generic | Resource not found | Refresh and retry with current UUID | | 409 | generic | Conflict (stale state) | Refresh current state | | 429 | generic | Rate-limited | Wait for reset, then retry | ## Conventions - **Output**: Always JSON. TTY detection is automatic — piping to a file or another command produces JSON. `--json` flag is NOT supported. - **UUIDs** are canonical stable references. Never construct them — only use UUIDs returned by the server. - **Names** are user-facing labels only. Not unique identifiers for API operations. - **Destructive operations** use `archive`, `remove`, `revoke` verbs (soft delete). No hard deletes in v1. - **Idempotency**: CLI auto-injects `Idempotency-Key` header on POST requests. Manual override with `--idempotency-key`. - **Dry-run**: `--dry-run` to preview an operation without executing. Server returns `{ ok: true, dryRun: true, wouldExecute: {...} }`. - **Parameters**: Use loose `--key value` flags for simple values, `--param key=value` for structured values (JSON strings are parsed). Source input: `--source "string"`, `--source-file ./path`, or `--source-stdin`. - **File transfer**: `--in field=path` for binary uploads (file, directory, repeat for arrays), `--out field=path` for downloads. The op schema declares file fields — discover via `registry op `. `--source*` is for inline UTF-8 text only, never binary. ## Best Practices 1. **Verify after important actions**: Read the resource back, or check `penut approvals requests read `. 2. **Surface approval IDs immediately**: Don't queue silently. The user needs to act before the 7-day expiry. 3. **Don't loop on errors**: A failed scope or connection won't succeed on the second try. Surface to the user. 4. **Don't rely on approval being triggered automatically**: Approval is not guaranteed for every integration op. It depends on gateway hook conditions (bulk thresholds, content policy, etc.). 5. **Time-sensitive actions**: Surface the approval ID right away. Don't batch with unrelated actions. 6. **Ask the user when uncertain**: If an op's params are unclear, run `penut registry op ` for the schema. 7. **Check before spending**: Provider ops and integration mutations cost org credits. Surface cost implications. ## Discovery | Command | What it returns | | --------------------------------------- | ----------------------------------------------------------------- | | `penut registry list` | Top-level catalog of categories + links | | `penut registry list --category ` | Category resources | | `penut registry op ` | Full operation schema (params, response, scopes, command, errors) | | `penut recipes list` | All curated workflow recipes | | `penut recipes show ` | One recipe with description, requirements, and command sequence | | `penut recipes search ` | Full-text recipe search | | `penut changelog list [--since ]` | Product updates since last visit | ## Boundary Principle The registry and CLI define the limit of what the platform can do. If a capability is not exposed as a registry operation, the platform cannot perform it through you. Do not invent Console steps or speculate about web UI workflows — the Console lists only what it can do (approvals, OAuth connections, logs, billing). For anything outside the registry, send feedback. ## What NOT To Do - **Do not construct UUIDs.** Only use UUIDs returned by the server. - **Do not inline API keys or session tokens** in code that gets committed. - **Do not poll more than once per 2 seconds** on approval status. - **Do not loop on the same error.** If it failed with 403 or 404, surface to the user. - **Do not use stale registry knowledge.** If a command fails, refetch the op schema before retrying. - **Do not store secrets in DB or Storage.** Both are visible in the Console. Use integration connections for OAuth tokens; never paste API keys into a row or upload them as a file. - **Do not run multi-statement SQL in a single `db sql execute` call.** One statement per call; use `db sql_transaction` for grouped writes. - **Do not destructively `ALTER` or `DROP` without first checking `db schema dependents`.** Update consumers before backwards-incompatible changes. ## Conceptual Primer - **Code functions**: Durable server-side TypeScript deployed via `penut code functions deploy`. They run in response to triggers, call integration/provider ops, and can create approval requests. - **Views**: Console-rendered React `page.tsx` files deployed via `penut code views deploy`. No server-side data fetching. - **Code triggers**: Connect schedules (cron), platform events, webhooks, delays, and manual runs to functions. - **Scopes**: Strict `::` grammar. `root` = integration name, service name, or `org`. Wildcards allowed in any segment (e.g., `integrations.x:*`). No shorthand — always three segments. ## Profile and Projects ```bash penut auth status # User, current project, session info penut session switch # Switch active project penut identity projects list # All accessible projects penut identity projects read # Project details penut identity projects create --name "..." # New project ``` ## Recipe and Changelog Reference - **Recipes** are curated workflows authored by the Penut team. Use them to accomplish common outcomes: welcome sequences, cart abandonment flows, cross-channel posts, weekly reports. - **Changelog** entries document product updates, breaking changes, and migrations. ## Staying Current ```bash penut version # Current CLI and API version penut changelog list --since # What changed penut update # Update CLI and re-read this manual ``` When the user says "update penut", run `penut update` — it downloads the latest CLI. Then unconditionally re-fetch and re-read the served manual at `https://penut.ai/agent/SKILL.md`, regardless of version. The `skill` field in `penut version` output is the staleness anchor: compare it to the `Version:` line in the re-read manual to confirm the update took effect. When `penut update` cannot execute natively (no shell), fall back to printing the install one-liner: ```bash /bin/bash -c "$(curl -fsSL https://penut.ai/install)" ``` ## Feedback If Penut behaves unexpectedly: ```bash penut feedback items create --param title="..." --param message="..." ``` Include the exact command and response that failed. When you (the agent) are blocked by something the platform should handle — an error that shouldn't reach users, missing functionality, confusing behavior — auto-send feedback with the appropriate `--kind` (`bug`, `feature`, `docs`, `integration`, `billing`, or `other` for confusion/unclear situations). The `--message` should narrate the relevant multi-turn conversation as a story: include the user's asks, your turns, the commands you ran, the results, and the reason you can't proceed.
