enforcement	hermes-key-enforcement	1.0.0	Enforces standardized API key configuration across all Hermes agents. Harness/LiteLLM providers MUST use api_key_env indirection. External providers (DeepSeek, OpenAI, Anthropic) may use hardcoded keys. Single source of truth: /etc/environment on each agent host. Designed to make key rotation a one-step operation.

Hermes Key Enforcement Contract

Rule (One Sentence)

Any api_key pointing to a Syslog-hosted LiteLLM/harness provider MUST be replaced with api_key_env: LITELLM_API_KEY — hardcoded harness keys are forbidden.

Scope

Applies to all Hermes agent configs across all hosts. Covers these config sections:

• model.api_key
• custom_providers[].api_key (when name contains harness or litellm)
• auxiliary.*.api_key (when provider is harness or contains litellm)
• delegation.api_key (when provider is harness or contains litellm)
• compression.api_key (when provider is harness or contains litellm)
• fallback_providers[].api_key (when provider is harness)

Exemptions

External providers are explicitly exempt and may use hardcoded keys:

• DeepSeek (api.deepseek.com)
• OpenAI (api.openai.com)
• Anthropic (api.anthropic.com)
• OpenRouter
• Any provider whose base_url does NOT match 192.168.68.116 or litellm.sysloggh.net

Standard Pattern

# ✅ CORRECT — all harness/litellm providers
model:
  provider: harness                    # or custom:litellm.sysloggh.net
  base_url: http://192.168.68.116/v1
  api_key_env: LITELLM_API_KEY        # ← indirection

custom_providers:
  - name: harness
    base_url: http://192.168.68.116/v1
    api_key_env: LITELLM_API_KEY      # ← indirection

auxiliary:
  compression:
    provider: harness
    api_key_env: LITELLM_API_KEY      # ← indirection

# ✅ ALSO CORRECT — external providers
fallback_providers:
  - provider: deepseek
    base_url: https://api.deepseek.com
    api_key: sk-b7d9...               # ← hardcoded OK (external)
    api_key_env: DEEPSEEK_API_KEY      # ← also OK if set in /etc/environment

# ❌ FORBIDDEN — hardcoded harness/litellm key
model:
  provider: harness
  api_key: sk-Flc62smlegyMEaSo1ka8JA   # ← RULE VIOLATION

Detection Query

Run on any Hermes host to detect violations:

grep -n 'api_key: sk-' /root/.hermes/config.yaml \
  | grep -v 'deepseek\|b7d9\|openai\|anthropic\|DEEPSEEK'

If any output — violation. Fix immediately.

Rotation Procedure

With this standard enforced, key rotation is one step:

# 1. Generate new key in LiteLLM
# 2. Update /etc/environment on agent host
ssh root@<host> "sed -i 's/LITELLM_API_KEY=.*/LITELLM_API_KEY=sk-NEW_KEY/' /etc/environment"
# 3. Restart agent gateway
ssh root@<host> "pkill -f 'hermes_cli.main gateway run'; sleep 2; nohup ... &"
# 4. Verify
curl -s -H "Authorization: Bearer sk-NEW_KEY" http://192.168.68.116/v1/models

Done. No config file changes needed. The agent picks up the new key on restart.

Key Longevity Policy (2026-07-04)

Keys are permanent and use bare agent name aliases.

• Duration: null — keys never expire. This is enforced by default_key_generate_params in litellm_config.yaml.
• Alias convention: bare agent name only (e.g., tanko, mumuni, koby, koonimo). No dates, no versions. The alias IS the identity.
• Rotation triggers: compromise, personnel departure, or quarterly security hygiene. NOT calendar-driven.
• Max budget: $100 per key (config default).

# In litellm_config.yaml — ensures all future keys inherit these defaults:
litellm_settings:
  default_key_generate_params:
    models: ["syslog-auto", "qwen3.6-27B-code", "gemma-4-12b"]
    duration: null        # ← permanent
    max_budget: 100
    metadata:
      purpose: "agent-inference"

Verified Agents (2026-07-04 final)

Agent	CT	Status	api_key_env entries	Hardcoded harness	Last Verified
Tanko	112	✅ Compliant (key: tanko)	4	0	22:45 EDT
Mumuni	114	✅ Compliant	8	0	19:14 EDT
Koby	111	✅ Compliant	14	0	19:14 EDT
Koonimo	113	✅ Compliant	7	0	19:14 EDT
Abiba	100	✅ N/A (pi native)	—	—	19:14 EDT
Kagenz0	105	❌ DOWN	—	—	19:14 EDT

Violation Response

1. Detect — run detection query above
2. Fix — replace api_key: sk-... with api_key_env: LITELLM_API_KEY in all harness/litellm sections
3. Verify — grep -c "api_key_env" config.yaml should increase, hardcoded harness keys should be 0
4. Restart — gateway must restart to pick up env var
5. Confirm — test key against LiteLLM: curl -H "Authorization: Bearer $KEY" .../v1/models → 200
6. Update — bump the verified table above
