opencode-kimi-full AGENTS.md

A guide for a plugin that lets OpenCode, a coding-agent application, connect to Moonshot's Kimi-for-Coding service in the same way as the official Kimi command-line tool.

In plain words
What is it for?
It helps maintain the OAuth login flow, request authorization handling, and compatibility with the Kimi-for-Coding endpoint.
Why use it?
It explains the service's entitlement-based login rules and prevents developers from replacing the required device login with unsupported API-key authentication.

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

opencode-kimi-full AGENTS.md 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.

AGENTS.md — working notes for coding agents (and humans)

This file is the single source of truth for any AI agent (or human) modifying this repo. Read it top-to-bottom before touching code. If something you learn here contradicts what you see in the code, the code wins — update this file in the same commit.

User-facing install / usage documentation lives in README.md. Do not duplicate it here.


Purpose

One plugin, one job: make opencode talk to Kimi's kimi-for-coding endpoint exactly the way the official kimi-cli does. Everything in this repo exists to minimize drift from upstream kimi-cli.

The one rule that matters

Moonshot's coding backend is entitlement-sensitive: the model-name string alone is not the whole story.

Every design decision here follows from that: we do device-flow OAuth to mirror official kimi-cli, we do not accept API keys in this plugin, and we do not let the upstream SDK attach its own Authorization header.

Non-goals

  • No support for any non-kimi-for-coding model. opencode already handles other Moonshot / Baseten / Alibaba-CN / etc. entries itself.
  • No support for static API keys. Users who want that can use a different opencode provider entry.
  • No custom SSE parser, tool-call normalizer, or message rewriter. @ai-sdk/openai-compatible already does SSE/reasoning_content correctly.

Architecture

Each source file has one job. Do not add new files unless the existing ones genuinely can't hold a new concern.

File Responsibility
src/constants.ts Pinned strings that must mirror upstream kimi-cli (version, endpoints, client id).
src/headers.ts The seven X-Msh-* / UA headers + the persistent ~/.kimi/device_id file.
src/oauth.ts Device-code start, device-code poll, refresh-token exchange, and GET /coding/v1/models discovery.
src/auth-store.ts Read/write opencode's auth.json entries for this provider.
src/auth-refresh.ts Lock-based token refresh with cross-instance coordination, ensureFreshStoredAuth for standalone callers.
src/index.ts Plugin entry (v1 PluginModule format). Wires auth (login + loader) plus the Kimi chat hooks/body rewrite.
src/usage.ts Fetch and parse Kimi subscription usage (/coding/v1/usages).
src/tui.tsx TUI slash command /kimi:usage — renders usage in an opencode dialog.

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.
