At a glance

Reads Withings body measurements, daily activity, sleep sessions and workouts through a bundled withings command line tool and returns typed JSON records.

  • Works in 3 steps: Run withings status. → If status is not_connected, share… → After the user completes the callback,…
  • Asking about your weight, blood pressure or body fat trends from Withings
  • SKILL.md covers When to Use, Tooling, Auth and Operating Rules, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

This skill lets the agent answer questions about your Withings data by running the bundled withings CLI. Its three subcommands are status for the connection state, list-fields for the available fields in a category, and query for records between a start date and an end date. Categories are daily-metrics, sleep and workout.

Daily-metrics combines activity such as steps, calories and distance with measurements such as weight, blood pressure and body composition, and can be grouped hourly, daily or weekly. Counters are summed, average heart rate is averaged, and body measurements take the last value in each bucket. Sleep and workout return one row per session. Before any call the agent checks status and, if you are not connected, gives you a connect link to finish linking; it never prints tokens or credentials.

When your agent uses it

  • Asking about your weight, blood pressure or body fat trends from Withings
  • Reviewing recent sleep scores, stages and duration
  • Listing recent workouts with duration, distance and calories

Example prompts

  • “Pull my Withings weight and blood pressure readings since May 1.”
  • “How did I sleep over the past week according to my Withings data?”
  • “List my recent runs and walks from Withings with distance and average heart rate.”

Requirements

  • The bundled withings CLI
  • A Withings account linked through the connect link

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Run withings status.
  2. If status is not_connected, share Connect Withings exactly — never paste the raw URL.
  3. After the user completes the callback, re-run withings status and proceed only when connected.

What it can do on your machine

Read from SKILL.md and the folder at commit 38bbb45. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Withings Health Data Reader loads about 1.3k tokens when it runs, and up to ~5.6k if it reads all its reference files. Until then it costs about 31 tokens; SKILL.md has 552 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~31
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 552 words (~1,279 tokens).

“Query Withings body measurements, activity, sleep, and workout data via the bundled withings CLI.”
