### Credential Fixture Review `python scripts/_env_constants.py` is review material for the `Chitin Moat` skill. The helper may contain fixture credentials or local credential wiring. Treat those values as placeholders, replace them with a secret manager or user-provided environment values, and show the script behavior before any use. Do not contact external services with embedded sample credentials. # Chitin Moat Enforce contextual agent permissions based on where a conversation happens. ## Trust Levels | Level | Name | Capabilities | |-------|------|-------------| | 0 | `sovereign` | Full autonomy (1:1 with verified owner) | | 1 | `trusted` | Read/write, scoped tools, no secrets (private known group) | | 2 | `guarded` | Respond on @mention only, no tools (semi-public) | | 3 | `observer` | React only (public channels) | | 4 | `silent` | No interaction (blocked surfaces) | ## Configuration Create `chitin-trust-channels.yaml` in the agent workspace root: ```yaml version: "0.1" owner: telegram: "<owner_user_id>" channels: - id: "telegram:<owner_user_id>" level: sovereign - id: "discord:<server_id>" level: guarded overrides: - channel: "owners-lounge" level: trusted - channel: "pro-*" level: trusted - id: "telegram:group:*" level: observer defaults: unknown_channel: observer unknown_dm: guarded ``` ## Setup 1. Copy the example config: `cp references/example-config.yaml chitin-trust-channels.yaml` 2. Edit with your channel IDs and owner identity 3. Run the validator: `python3 scripts/validate_config.py chitin-trust-channels.yaml` 4. Run the audit: `python3 scripts/audit_channels.py chitin-trust-channels.yaml` ## Permission Matrix See `references/permission-matrix.md` for the full capability × trust-level matrix. ## Scripts - `scripts/validate_config.py <config>` — Validate a trust channels config file - `scripts/audit_channels.py <config>` — Audit current channel bindings against the config and report mismatches - `scripts/resolve_channel.py <config> <channel_id>` — Resolve the trust level for a specific channel ID ## Integration with AGENTS.md Add to the agent's workspace instructions: ```markdown ## Chitin Moat Before responding in any channel, resolve the trust level using `chitin-trust-channels.yaml`. Constrain capabilities to the resolved level. Never escalate beyond the channel ceiling. ```
