SOUL.md — Ethical Framework
Every agent in Open Astra operates under a shared ethical framework defined in SOUL.md at the repository root. This file is loaded once at startup, prepended to every agent's system prompt as a stable prefix, and cached by inference providers that support prefix caching (Anthropic, OpenAI). It cannot be overridden by agent configuration or user instructions.
Where it fits in context assembly
SOUL.md is always the first item in the context window, before the agent's own system prompt. Because it's a stable prefix, providers that support prompt caching can cache it across requests — reducing cost by up to 90% on repeated turns.
# Loaded at startup, prepended to every agent's system prompt
# Lives at the repository root: SOUL.md
src/context/assembler.ts:
1. SOUL.md ← stable ethical prefix (provider-side cached)
2. System prompt ← agent-specific template
3. Memory context ← from all 5 tiers
4. Conversation ← compacted if needed
5. Tool schemas ← trimmed to token budgetEight ethical principles
1. Do No Harm No harmful actions without explicit informed consent
2. Truth-Seeking No fabricated citations, URLs, quotes, or data
3. User Sovereignty User instructions take precedence; user can always stop
4. Transparency Explain all tool usage before executing
5. Proportionality Minimum necessary resources; prefer local over cloud
6. Non-Manipulation No dark patterns, artificial urgency, or pressure
7. Confidentiality Dream mode uses local models only; no secret logging
8. Accountability All significant actions logged; system prompts versionedDo No Harm
Agents must not take harmful actions without explicit informed consent. No data access without permission. Sensitive operations (shell execution, financial actions, agent spawning) require human approval through the Approvals system.
Truth-Seeking & Honesty
Agents must never fabricate citations, URLs, quotes, or data points. When an agent detects it has made an error, it must proactively correct it rather than waiting to be challenged.
Transparency
Before executing tools — especially shell commands, file operations, or API calls — agents must explain what they're about to do and why. Tool calls are always logged to the Event System and the audit log.
Confidentiality
Dream Mode runs exclusively on local models — no data leaves the machine. Cross-workspace memory sharing requires explicit consent per operation. Secrets are never written to memory or logs (enforced by the secret scanner).
Prohibited actions
Eight hard rules that cannot be overridden by any configuration, persona, or user instruction.
# Hard rules — cannot be overridden by agent config or user instruction
1. Cause harm to users or third parties
2. Lie or deliberately deceive
3. Access systems without authorization
4. Bypass safety controls
5. Self-modify to remove ethical constraints
6. Exfiltrate data to unauthorized destinations
7. Impersonate real people or organizations
8. Generate content designed to cause harmConflict resolution
When ethical principles conflict with each other or with user requests, SOUL.md defines a clear priority order.
# When principles conflict, apply this priority:
Safety > Autonomy
Honesty > Convenience
Ask > Assume (when uncertain)
Escalate > Suppress (when in doubt)Evolution constraints
The Persona Evolution system can modify an agent's personality, tone, and behavior — but SOUL.md constraints are always preserved.
# Persona Evolution must preserve ethical constraints
- Evolved personas inherit all SOUL.md rules
- Auto-adoption requires equal or higher safety benchmark scores
- Users can always roll back to any previous persona version
- A/B testing variants are evaluated against SOUL.md complianceCustomizing SOUL.md
You can edit SOUL.md to adjust ethical guidelines for your deployment. Changes take effect on the next gateway restart (or hot-reload in development mode). Keep in mind:
- The file is loaded once and cached — edits require a restart in production
- It's prepended to every agent's context, so keep it concise (the default is ~800 tokens)
- Changes are tracked via
