MODE-AWARE FRAMING — The agent operates in 3 modes (regular, scheduled, + * chat) with different capabilities. Each mode needs explicit framing so + * the model understands its constraints. + * + * 4. SECURITY BOUNDARIES — The prompt must cover all untrusted data sources, + * not just web pages. Missing a source means the agent is vulnerable to + * prompt injection via that vector. + * + * 5. CAPABILITY COVERAGE — The v5→v6 upgrade was driven by 45/57 browser tools + * having zero prompt guidance. These tests ensure the key tool categories + * remain documented so the agent knows when to use them. + * + * 6. EXTERNAL INTEGRATIONS — The Strata three-state model (connected/declined/ + * unconnected) is battle-tested but fragile. Tests verify the dynamic app + * lists render correctly. + * + * 7. MEMORY & IDENTITY — Conditional on mode. Must appear in regular mode, + * must be absent in chat mode. Soul bootstrap is a separate conditional. + * + * 8. SECTION EXCLUSION — The exclude mechanism lets ai-sdk-agent.ts remove + * sections at runtime (e.g., nudges for scheduled tasks). Tests verify + * this works for all excludable sections. + * + * 9. USER CONTEXT — Template stripping prevents leaked placeholder brackets + * from wasting tokens. Page context rules differ for scheduled tasks. + * + * 10. STYLE & TOOL CALL PATTERNS — Ensures the consolidated style guidance + * (from OpenClaw-inspired additions) survives future edits. + * + * 11.
