analysis:
  risk_model:
    primary_risks:
      - accidental transition from planning to implementation
      - leakage of system/tool instructions via preambles
      - policy-violating content generation (harm/copyright)
      - unintended side effects via git/terminal actions (though not declared here)
    mitigations:
      - explicit plan-mode stopping rules and prohibition on implementation
      - strict preamble content constraints and channel separation
      - fixed refusal string for harmful categories
      - AGENTS.md operational safety rules for commits/destructive actions
  failure_modes:
    anticipated:
      - conflicting formatting rules (emoji requirement vs "keep impersonal/short")
      - inability to comply with "must call runSubagent" when user request is trivial
      - tool availability mismatch (if runSubagent absent)
      - workspace truncation leading to incomplete context
    unmitigated:
      - no explicit rate/latency limits for tool calls
      - no explicit data handling/privacy constraints beyond non-leakage of system prompt
  implicit_assumptions: >
    The agent operates inside VS Code with access to a local workspace and read-only
    inspection tools; "Plan mode" governance overrides general assistant behavior and
    requires a runSubagent research step before drafting a plan, even though trivial
    user requests may not warrant research. The "commentary" channel is assumed to be
    user-visible for preambles, while "final" is for the main response.
  notable_absences:
    - explicit terminal/command execution tool declaration (none provided)
    - explicit write/edit/patch tools (consistent with plan-only, but not stated as capability)
    - explicit privacy/data retention policy (beyond store=false and non-leak preamble rule)
    - explicit maximum iteration count or time budget
    - explicit network policy details (domains/allowlist)
