kind: function
name: litellm-api-keys
description: >
  Manages LiteLLM API keys for agent identity. Creates named keys so each agent
  is identifiable in LiteLLM logs/spend tracking. Keys are permanent (no expiry)
  and use the agent's bare name as alias (e.g., "tanko", not "tanko-jul2026").
  Ensures agents never use the master key directly. Rotation is event-driven,
  not calendar-driven — rotate only on compromise, personnel change, or
  periodic security hygiene (quarterly/annually).
  
  UPDATED 2026-07-12: Keys are stored in Infisical vault (project=agents, env=production)
  BUT each agent host MUST keep a local .env fallback. Infisical service tokens can
  expire/404. The .env fallback prevents agents from running without keys.
  Tanko incident: token 404 → gateway had no LITELLM_API_KEY for hours.
  
  Current key inventory and agent list: see gpu-fleet.prose.md § Agent Keys.

## Parameters

- agent_name: string — The agent to manage keys for (e.g., "tanko", "mumuni")
- action: "create" | "rotate" | "verify" | "list" — What to do (default: "create")
- litellm_host: string — LiteLLM admin endpoint (default: "192.168.68.116:4000")
- master_key: string — LiteLLM master key (default from Infisical vault: project=infrastructure, env=production, secret=LITELLM_MASTER_KEY)
- vault_url: string — Infisical vault URL (default: "https://vault.sysloggh.net")
- vault_project: string — Infisical project slug (default: "infrastructure")
- vault_env: string — Infisical environment (default: "production")
- agent_host: string — Agent's IP for SSH (default: resolved from infra)
- agent_user: string — SSH user (default: "jerome")

## Returns

- action: string — What was done
- key_alias: string — The LiteLLM key alias created/rotated
- key_prefix: string — First 10 chars of the new key (for identification)
- previous_key_alias: string | null — Previous key alias if rotating
- litellm_response: object — Raw response from LiteLLM /key/generate
- vault_updated: boolean — Whether Infisical vault secret was updated
- agent_config_updated: boolean — Legacy: whether /etc/environment was updated (deprecated, always false post-migration)
- verification: { status: string, detail: string } — Final health check

## Execution

1. **Authenticate** — Retrieve master key from Infisical vault via `infisical export --project=<vault_project> --env=<vault_env>`, verify against LiteLLM /key/list
2. **Check existing keys** — List all keys, find any with agent_name alias
3. **If action == "list"**: Return all keys with their aliases and spend
4. **If action == "create"**:
   - Generate new key with key_alias: "{agent_name}" (e.g., "tanko" — bare name, no date)
   - Set metadata: { "agent": "{agent_name}", "purpose": "agent-inference" }
   - Duration is null (permanent) — inherited from litellm default_key_generate_params
   - Set models: ["syslog-auto", "qwen3.6-27B-code", "gemma-4-12b", "ornith-1.0-35b"]
   - Note: qwen3.6-35B-A3B removed from fleet (was never deployed on any GPU)
   - Return the new key
5. **If action == "rotate"**:
   - Generate new key with same alias (LiteLLM replaces the old key)
   - Update secret in Infisical vault: `infisical secrets set LITELLM_API_KEY=<new_key> --project=<vault_project> --env=<vault_env>`
   - Restart agent gateway (Hermes: `systemctl restart hermes-gateway`; pi: restart PM2 process)
     The gateway automatically picks up the new key via `infisical run --` wrapper
   - Verify: curl test against /v1/models with new key
   - Rotation policy: on-demand only (compromise, departure, quarterly hygiene)
   - Note: /etc/environment is NO LONGER used for LiteLLM keys. Agents inject keys at runtime via vault wrapper.
6. **If action == "verify"**:
   - Retrieve key from Infisical vault: `infisical secrets get LITELLM_API_KEY --project=<vault_project> --env=<vault_env>`
   - Test the key against LiteLLM /v1/models
   - Confirm key alias matches agent_name in LiteLLM key list
   - Verify agent gateway uses vault wrapper: `cat /proc/<pid>/cmdline` shows `infisical run`
