hzhang 01577ddfe8 feat: Plexum-kimi-provider v0.1 — Moonshot Kimi via coding endpoint

Plexum ProviderPlugin that serves Moonshot Kimi K2.6 ("Kimi for
Coding") via Kimi's Anthropic-compatible coding endpoint at
https://api.kimi.com/coding/v1/messages. Port of openclaw's
extensions/kimi-coding/provider-catalog.ts to Go + Plexum SDK.

Repo structure parallels Plexum-minimax-provider:
- internal/anthropic/    HTTP+SSE Anthropic Messages client, with new
                         UserAgent field (Kimi expects "claude-code/
                         0.1.0" — openclaw plugin parity)
- internal/translate/    canonical ↔ Anthropic translator (re-used
                         shape from MiniMax — no Kimi-specific quirks
                         needed for v1 plain-text path)
- cmd/plexum-kimi-provider-plugin/  ProviderPlugin entry

Declared models (Kimi server accepts all three; plugin normalizes
legacy aliases to the canonical id on the wire):
  kimi-for-coding      (current, default)
  kimi-code            (legacy alias)
  k2p5                 (legacy alias)

HostConfig: api_key (required), base_url (override), user_agent
(default "claude-code/0.1.0"), max_tokens_default (default 8192).

End-to-end verified against the live `sk-kimi-` subscription key:

1. CLI embedded turn 1:    "Hi there! I'm Kimi."
2. CLI embedded turn 2:    "I said hi, I'm Kimi." (multi-turn context OK)
3. Via gateway socket:     {"outcome":"text","text":"...pong"}
4. Via Fabric channel:     alice → bt2-clean → kimi agent → Kimi K2.6 →
                           outbound REST → reply in channel seq=15:
                           "Concise concurrency: goroutines and channels
                            make parallel code readable, safe, and
                            efficient without the usual threading
                            complexity."

Test the bidirectional channel pipeline works with a fresh provider:
Fabric (channel plugin) + Kimi (provider plugin) wired through Plexum
agentloop, MiniMax-style plugin packaging.

Plexum-kimi-provider

Plexum ProviderPlugin that serves Moonshot Kimi K2.6 ("Kimi for Coding") via Kimi's Anthropic-compatible coding endpoint (https://api.kimi.com/coding/v1/messages).

Port of openclaw/extensions/kimi-coding/provider-catalog.ts to Go + Plexum SDK.

Status

v0.1 — current: API key auth (Kimi subscription sk-kimi-...), streaming SSE, models kimi-for-coding / kimi-code / k2p5. Sends User-Agent: claude-code/0.1.0 (mirrors openclaw plugin) for parity with Kimi's coding subscription auth path.

Install

cd ~/Plexum-kimi-provider
./scripts/install.sh

Then:

Write API key to ~/.plexum/plugins/plexum-kimi-provider/config.json:
```
{"api_key": "sk-kimi-..."}
```
(chmod 600 it.)

Allow the plugin in ~/.plexum/plexum.json:

{"plugins": {"allow": ["plexum-kimi-provider"]}}

Point an agent at Kimi:

plexum agent-add --model kimi-for-coding my-agent

Restart and talk:

systemctl --user restart plexum
plexum say --agent-id my-agent --session-id $(plexum new-session --agent-id my-agent) "hello"

Config options

Field	Default	Notes
`api_key`	(required)	`sk-kimi-...` subscription key
`base_url`	`https://api.kimi.com/coding`	override only if you proxy
`user_agent`	`claude-code/0.1.0`	matches openclaw plugin
`max_tokens_default`	`8192`	used when TurnRequest.MaxTokens unset

Model id aliases

Kimi server accepts all three; the plugin normalizes to kimi-for-coding on the wire for consistent logs:

advertised id	wire id
`kimi-for-coding`	`kimi-for-coding`
`kimi-code` (legacy)	`kimi-for-coding`
`k2p5` (legacy)	`kimi-for-coding`

Architecture

Same shape as Plexum-minimax-provider:

internal/anthropic/ — HTTP+SSE Messages client (now with UserAgent field; can be shared by future Anthropic-compat providers)
internal/translate/ — canonical ↔ Anthropic translator
cmd/plexum-kimi-provider-plugin/ — ProviderPlugin entry

License

Same as Plexum.
