A command-line tool for reading and managing Hevy workout data from a terminal. Hevy is an app for tracking workouts, exercises, routines, and body measurements.

Use it to list or inspect workouts and routines, search exercises, review exercise history and measurements, view summaries, and create or update supported Hevy records.

It lets the agent work with training records from scripts or terminal commands without needing to use the app’s interface. It also keeps the API key in a dedicated environment variable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00038	$0.01343
Opus 5.5	$0.00015	$0.00537
Sonnet 5.5	$0.00008	$0.00269
Haiku 4.5	$0.00004	$0.00134

Security

Grade A, and why

hevy-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Hevy CLI

Use this skill to manage workouts in the Hevy app. The CLI supports reads, creates, and updates. Deletion is unsupported.

1. Install or run the published package

# One-off use; npm downloads the published package when needed.
npx @chrisdoc/hevy-cli --help

# Local project install.
npm i @chrisdoc/hevy-cli
npx hevy --help

# Persistent global install.
npm i -g @chrisdoc/hevy-cli
hevy --help

The package requires Node.js 24 or newer. Use npx --yes @chrisdoc/hevy-cli ... in non-interactive scripts. Installation is verified when npx @chrisdoc/hevy-cli --version or hevy --version prints a version.

2. Configure the API key

The CLI reads credentials only from HEVY_API_KEY:

export HEVY_API_KEY='<your-hevy-api-key>'

Keep the key out of command arguments, JSON payloads, URLs, shell history, screenshots, logs, and responses. --help and --version work without it.

3. Choose a route

Read routes:

user
workouts list, workouts get, workouts count, workouts events
routines list, routines get
exercises search, exercises get, exercises history
measurements list, measurements get
summary

Create/update routes:

workouts create, workouts update <workout-id>
routines create, routines update <routine-id>
exercises create
folders create
measurements create <YYYY-MM-DD>, measurements update <YYYY-MM-DD>

The CLI exposes no delete, update-exercise-template, or update-folder routes. If a user requests deletion of any resource, explain that deletion is not supported by the CLI or the Hevy API integration. Suggest a supported alternative, such as archiving the resource in Hevy if available or replacing it.

Run route help whenever a flag or argument is uncertain:

npx @chrisdoc/hevy-cli <command> --help

Use the narrowest read route and date/page range that answers the question. Use --json when output will be searched, filtered, or piped.

For exercise work, search first and use the exact returned template ID. Create a custom exercise only when the required movement is absent:
