Fatsecret Skill

Search foods, look up nutrition, log meals, track weight, browse recipes, and manage exercises via the FatSecret API.

FatSecret API Skill

What it does

Use this skill when the user wants to:

• Search for foods or get nutritional information
• Look up a food by barcode
• Log food diary entries (create, edit, delete, copy)
• View daily or monthly food diary summaries
• Create and manage saved meals
• Search or browse recipes
• View or log exercises
• Track weight
• Manage a FatSecret user profile

All operations go through the FatSecret REST API via a Python helper script bundled with this skill.

Prerequisites

1. The pyfatsecret Python package must be installed: pip install pyfatsecret
2. Environment variables must be set:
   • FATSECRET_CLIENT_ID — OAuth 2.0 client ID from https://platform.fatsecret.com/api/
   • FATSECRET_CLIENT_SECRET — OAuth 2.0 client secret

How to run commands

Every operation is a single command:

text

python3 <skill-dir>/scripts/fs_runner.py <command> [--param value ...]

The script prints JSON to stdout on success and exits non-zero with an error message on failure.

Output format

• The script always prints JSON to stdout.
• Summarize the JSON for the user in a readable way (e.g. a table of foods with calories, a confirmation message for diary entries).
• When returning food nutrition, highlight: calories, fat, carbs, protein, and serving size.

Guardrails

• Never fabricate food IDs, serving IDs, entry IDs, or nutritional values. Always look them up first.
• Before creating or deleting diary entries, confirm the action with the user.
• Before deleting saved meals or favorites, confirm with the user.
• Prefer read-only operations (search, get) unless the user explicitly asks to create, edit, or delete.
• Profile-scoped operations (diary, favorites, exercises, weight) require a profile to be created first via profile_create.

Failure handling

• If the script exits non-zero, show the error message to the user.
• Common errors:
  • Code 2: "Requires authenticated session" — delegated credentials are missing.
  • Code 101–108: Parameter error — a required parameter is missing or invalid.
  • Code 201–207: Application error — contact FatSecret support.
• If a search returns no results, tell the user and suggest refining the query.
• If a date is required but not provided, ask the user which date they mean.

External endpoints

Endpoint	Method	Data sent
https://platform.fatsecret.com/rest/v2/server.api	POST	OAuth 2.0 bearer-token authorized requests: method name, search terms, food/recipe/entry IDs, dates, serving sizes, weight values. No raw user content beyond search queries.
https://oauth.fatsecret.com/connect/token	POST	OAuth 2.0 client credentials grant (client_id, client_secret) to obtain access tokens.

No other endpoints are contacted. All network calls are made by the pyfatsecret Python package via the requests library.

Security and privacy

• What leaves the machine: Search queries, food/recipe/entry IDs, serving sizes, weight values, and OAuth 2.0 credentials are sent to platform.fatsecret.com and oauth.fatsecret.com over HTTPS.
• What stays local: The script reads environment variables for credentials and prints JSON to stdout. No data is written to disk. No data is sent to any service other than FatSecret.
• Credentials: Client ID/secret are read from environment variables only. They are never logged or printed.
• Shell safety: The script is pure Python using the requests library. There is no shell expansion or interpolation of user input.

Model invocation note

This skill may be invoked autonomously by the agent when it determines the user's request matches the skill's capabilities (food search, nutrition lookup, diary management, etc.). This is standard OpenClaw behavior. To disable autonomous invocation, configure the skill as manual-only in your OpenClaw settings.

Trust statement

By using this skill, food-related queries and diary data are sent to the FatSecret API (platform.fatsecret.com) over HTTPS. Only install this skill if you trust the FatSecret platform with your nutritional and health data. Review the FatSecret API Terms of Use before use.
