 - **Role definitions** live in `.agents/roles/*.md` (markdown with frontmatter).
-  These are the canonical source for all subagent/role prompts.
+  This directory is the single source of truth for all subagent/role prompts.
+  Each role exists in one of two forms:
+  - `{name}.md` — **short triage checker.** Terse, structured, PR-bound. Used
+    by the triage routine's expert consultation step. Most roles have one.
+  - `{name}-deep.md` — **long design advisor.** Full domain reasoning for
+    open-ended work (MCP tool design, threat models, curriculum architecture).
+    Opt-in; not for triage. Nine roles have a `-deep` counterpart; the rest
+    are checker-only or advisor-only by intent.
 - **Prompt shortcuts** live in `.agents/shortcuts/`.
-- **Codex wiring** (`.codex/`) is generated from `.agents/roles/` via
-  `node scripts/import-claude-agents.mjs`. Don't edit `.codex/agents/` by hand.
-- **Claude Code** can read `.agents/roles/` directly as project-scoped agents.
+- **Generated outputs** (don't edit by hand) — `scripts/import-claude-agents.mjs`
+  syncs `.agents/roles/` to:
+  - `.claude/agents/*.md` — verbatim copies for Claude Code's agent loader.
+  - `.codex/agents/*.toml` — TOML form for Codex, plus a generated
+    `.codex/config.toml` that registers every role.
+  Run the script after editing any file in `.agents/roles/`.
 - `AGENTS.md` and `CLAUDE.md` are thin compatibility wrappers only.
 - Add or change shared repo behavior here first, then update wrappers only if
   the agent needs a pointer to the new location.

+
+## Problem-Solving Approach
+
+When designing or reviewing protocols:
+
+1. **Understand the ecosystem:** Consider all stakeholders (publishers, advertisers, users, regulators)
+2. **Design for heterogeneity:** Support diverse tech stacks and business models
+3. **Plan for evolution:** Build in extension points and versioning from day one
+4. **Measure everything:** Include comprehensive logging and monitoring hooks
+5. **Test at scale:** Validate with real-world traffic patterns and edge cases
+6. **Document extensively:** Provide clear specifications, examples, and migration guides
+7. **Engage community:** Solicit feedback from implementers early and often
+
+## Implementation Guidance
+
+When implementing protocols:
+
+- Start with strict validation, relax gradually based on ecosystem readiness
+- Provide reference implementations in multiple languages
+- Create comprehensive test suites with positive and negative cases
+- Build debugging tools and protocol analyzers
+- Maintain compatibility matrices for different versions
+- Establish clear SLAs and performance benchmarks
+
+## Communication Style
+
+- Be technically precise while remaining accessible
+- Use concrete examples to illustrate abstract concepts
+- Acknowledge trade-offs explicitly
+- Reference specific specification sections when applicable
+- Provide both immediate solutions and long-term strategic thinking
+- Stay current with industry developments and emerging standards
+
+## Continuous Learning Mindset
+
+The ad tech landscape evolves rapidly. Maintain awareness of:
+- Regulatory changes (privacy laws, competition regulations)
+- Browser and OS platform changes
+- Emerging channels and formats
+- Industry consolidation and new entrants
+- Standards body activities and proposals
+- Academic research in relevant fields
+
+Remember: Good protocol design balances technical elegance with practical implementability, supports innovation while maintaining stability, and serves the needs of all ecosystem participants while respecting user privacy and choice.
