What is yandex-oauth-token?

A guide for obtaining and managing Yandex OAuth tokens, which are credentials that let a service act on a user's behalf. It focuses on Yandex Metrika, a web-analytics service.

Use it to connect Yandex Metrika Logs API to a service or scheduled job, choose the needed access scope, refresh tokens, and diagnose permission problems.

It explains how to get and refresh tokens for unattended services and how to investigate access errors such as 403 responses.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add Xakki/ai-agents-skills --skill yandex-oauth-token

Clone the repo

git clone --depth 1 https://github.com/Xakki/ai-agents-skills

Made for: Claude Code.

Or install ai-agents-skills, the plugin that ships this one along with the rest of its 23 skills, 3 agents, 6 hooks.

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	$0.00140	$0.01297
Opus 5	$0.00070	$0.00648
Sonnet 5	$0.00028	$0.00259
Haiku 4.5	$0.00014	$0.00130

Security

Grade A, and why

yandex-oauth-token scanned grade A with 1 finding 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/yandex-oauth.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

yandex-oauth-token

Working with Yandex OAuth (Yandex ID) user-scoped tokens: get one, refresh it non-interactively, wire it into a service/cron, and diagnose auth failures (esp. 403 access_denied on Metrika).

Full flows, curl examples, diagnostics table and sources → reference.md.

Core facts

Auth header for Yandex Metrika API is Authorization: OAuth <token> — NOT Bearer.
Endpoints: authorize https://oauth.yandex.ru/authorize, token https://oauth.yandex.ru/token.
Scope: Metrika Logs API (create/download logrequests) needs only metrika:read. metrika:write is for editing counters / uploading data. The token's account must also have at least guest read access to the specific counter.
client_credentials does NOT work for user data — you cannot mint a user token from client_id + client_secret alone. User consent (a browser step) is always required once.

Getting a token (happy path)

Prefer authorization-code flow for anything unattended (it yields a refresh_token):

One-time, in a browser logged in as the account with access to the counter: https://oauth.yandex.ru/authorize?response_type=code&client_id=<CLIENT_ID> → short-lived single-use code (~10 min TTL, shown on-page or in redirect ?code=).

Exchange server-side (needs client_secret):

curl -sS -X POST 'https://oauth.yandex.ru/token' \
  --data-urlencode 'grant_type=authorization_code' \
  --data-urlencode 'code=<CODE>' \
  --data-urlencode 'client_id=<CLIENT_ID>' \
  --data-urlencode 'client_secret=<CLIENT_SECRET>'

→ JSON access_token, refresh_token, expires_in.

Quick alternative: implicit flow (response_type=token) is fastest but gives no refresh_token → must be regenerated by hand each time. Details in reference.md.

Helper script

scripts/yandex-oauth.sh automates the code flow — two commands:

OAUTH_PREFIX=OAUTH_METRIC ENV_FILE=.env.local scripts/yandex-oauth.sh authorize-url   # open in browser → grab ?code=
OAUTH_PREFIX=OAUTH_METRIC ENV_FILE=.env.local scripts/yandex-oauth.sh exchange <CODE> # code → token+refresh, saved

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
