oura-api-skill is a skill for Claude Code from YasuakiOmokawa/oura-mcp. It costs 43 tokens per session (1,222 once invoked), scanned A, original, MIT.

A reference guide and collection of recipes for the Oura Ring API v2. The API is a way for software to read Oura data such as sleep, activity, readiness, heart rate, and workouts.

In plain words
What is it for?
Use it when answering questions about Oura data or retrieving sleep, activity, readiness, heart-rate, workout, and other Oura records through oura-mcp.
Why use it?
It explains authentication, date formats, time zones, and API paths so an agent can request Oura data correctly.

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.

Fable 5.1 $0.00043 $0.01222
Opus 5 $0.00022 $0.00611

Security

Grade A, and why

oura-api-skill 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 11d 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.

Oura API Skill

This skill documents how to use oura-mcp (a Model Context Protocol server for Oura Ring API v2).

Setup

Run npx @yasuakiomokawa/oura-mcp configure once to set up OAuth credentials. After that, MCP clients (Claude Desktop, Claude Code, Cursor) can call the tools below.

Tools

  • oura_authenticate — re-authenticate via browser (after refresh_token expiry).
  • oura_auth_status — check token state.
  • oura_clear_auth — wipe stored tokens.
  • oura_api_get — generic GET, e.g. path: "/v2/usercollection/daily_sleep". Use max_pages for large time-series.
  • oura_api_list_paths — see all available endpoints.

Date conventions

  • Daily endpoints (/daily_*): start_date / end_date in YYYY-MM-DD. Default to last 7 days when user is vague.
  • Time-series (heartrate): start_datetime / end_datetime in ISO 8601 UTC, e.g. 2026-05-01T00:00:00Z.
  • Time-of-day phrases (「朝」「夜」 etc.) are user-local. When the prompt is Japanese, assume JST (UTC+9) for the conversion to UTC unless the user states otherwise; otherwise infer from personal-info or ask.
  • Natural-language phrases (treat as inclusive of today unless user contradicts):
    • 「先週」「last week」 → last 7 days ending today
    • 「今週」「this week」 → Monday of this week → today
    • 「先月」「last month」 → previous calendar month (1st → last day)
    • 「今月」「this month」 → 1st of this month → today
    • 「Nヶ月」「last N months」 → last N×30 days ending today (treat as approximate, not calendar-exact)
    • These phrase-resolved windows count as explicit user intent — recipes that say "honor user's explicit range" must use the resolved window, not their own default.
  • Recipe-level windows override the vague-default (last 7 days). If a recipe specifies a window (e.g., 14 days for diagnostic, 90 days for personal-best mining) AND the user did not give a phrase, follow the recipe.

Pagination

Most endpoints return { data: [...], next_token: "..." | null }. By default oura_api_get fetches one page. Pass max_pages: N (1-20) for auto-follow, or pass params: { next_token: "..." } manually.

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.
