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.

Security

Grade A, and why

strava-sync 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 10d 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.

Strava Training Log Sync

Overview

This skill downloads training data from Strava using the Strava MCP server and creates weekly markdown summaries in the training-log folder. Each week is stored as a single markdown file with detailed activity summaries, including lap details for runs marked as workouts.

Note: This is a Strava-specific data import tool. The running coach system also supports:

  • Other platforms (Garmin Connect, Apple Health, Polar Flow, etc.) - athlete provides data
  • Manual training logs - athlete creates markdown files directly
  • Conversational input - athlete describes training verbally

This skill uses MCP tools specific to Strava (mcp__strava__*). Similar skills could be created for other platforms using their respective APIs or MCP servers.

Workflow

1. Get Week Number from User

First, ask the user to provide the training week number:

  • Prompt: "Which training week would you like to sync? (e.g., 1, 2, 3)"
  • Store this number as the week identifier
  • The file will be saved as week-{n}.md where {n} is this week number

2. Check Strava Connection

Verify that Strava is connected:

# Check connection status

Use the mcp__strava__check-strava-connection tool to verify the connection. If not connected, use mcp__strava__connect-strava to authenticate.

3. Fetch Recent Activities

Retrieve the last 7 days of activities from Strava:

  1. Use mcp__strava__get-recent-activities to fetch recent activities (default 30 activities)
  2. Filter activities to only those from the last 7 days
  3. Calculate the week date range (e.g., "2024-01-15 to 2024-01-21")

4. Process Each Activity

For each activity in the last week:

  1. Extract key information:

    • Activity name
    • Date and time
    • Activity type (Run, Ride, Swim, etc.)
    • Distance (convert to miles or km)
    • Duration (format as HH:MM:SS)
    • Elevation gain
    • Average pace/speed
    • Average heart rate (if available)
    • Description/notes
  2. Check if the activity is marked as a workout:

    • Look for the workout_type field in the activity data
    • For runs: workout_type 0 = default run, 1 = race, 2 = long run, 3 = workout

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
