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

adjust 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 2d 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.

What it actually says

/adjust — Modify Upcoming Workouts

The user will provide a reason (e.g., "feeling tired", "knee is sore", "need to swap Thursday and Friday").

Calendar modification requires Intervals.icu. If it is not configured, provide a proposed plan in text and state that the athlete must add it to their own calendar.

  1. Read relevant knowledge base files based on the reason:
    • Fatigue/soreness: knowledge/recovery-overtraining.md, knowledge/injury-prevention.md
    • Schedule change: knowledge/periodization.md (preserve weekly structure principles)
    • Feeling great: knowledge/volume-progression.md (safe ramp limits)
    • Pain/injury concern: knowledge/injury-prevention.md (always recommend medical consultation first)
  2. Fetch data using MCP tools (call them directly, in parallel where possible):
    • Wellness endpoint for the last 3 days
    • Fitness endpoint for the last 7 days
    • Events endpoint for the next 7 days
  3. Analyze the user's reason against the data:
    • If fatigue/soreness: consider reducing volume/intensity, adding rest
    • If schedule change: swap or move workouts while preserving weekly structure
    • If feeling great: consider modest additions (never reckless increases)
  4. Display:
    • Current Status: Wellness + form summary
    • Proposed Changes: Table showing each affected day with before → after
    • Clear explanation of why each change is being made, citing training science from the knowledge base
  5. WAIT FOR USER CONFIRMATION — explicitly ask "Should I apply these changes?" before calling the update event, create event, or delete event endpoints
  6. Only after user confirms, apply the changes and show confirmation of what was updated
Changes

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.
