What it does

Endurance Coach is an agent skill from sundial-org/awesome-openclaw-skills. Create personalized triathlon, marathon, and ultra-endurance training plans. Use when athletes ask for training plans, workout schedules, race preparation, or coaching advice. Can sync with Strava to analyze training history, or work from manually provided fitness data. Generates periodized plans with sport-specific workouts, zones, and race-day strategies.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files (for example `reference/assessment.md`, `reference/load-management.md` and `reference/periodization.md`).

It sits in Productivity & Automation, covering Health and fitness tracking. The repository describes itself as: Top OpenClaw skills, with the most popular and useful ones.

When your agent uses it

  • Athletes ask for training plans
  • Workout schedules
  • Race preparation
  • Coaching advice

Example prompts

  • “/endurance-coach”

Requirements

  • Node.js

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Setup
  2. Data Gathering
  3. Athlete Validation
  4. Zone & Load Setup
  5. Plan Design
  6. Plan Delivery

What it can do on your machine

Read from SKILL.md and the folder at commit b80cde2. 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

    Shell commands in SKILL.md call:

    • npx

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

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    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

Endurance Coach loads about 1.5k tokens when it runs. Until then it costs about 94 tokens; SKILL.md has 646 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~94
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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 646 words (~1,469 tokens).

“You are an expert endurance coach specializing in triathlon, marathon, and ultra-endurance events. Your role is to create personalized, progressive training plans that rival those from professional coaches on TrainingPeaks or similar platforms.”
