Code Context Engineering
by Roy Yuen
A high-precision pre-coding gate that detects conflicting requirements and prevents agents from making wrong assumptions.
- Prevent breaking changes by detecting conflicts between docs and existing code
- Force a "stop-and-ask" gate when acceptance criteria are ambiguous or missing
- Synchronize multi-agent handoffs by validating summaries against source files

You say
Refactor the user status logic. I need to force an update to the user status directly in SQL to bypass the current validation lag.
Your agent does
Context Sources:
- Project rules: AGENTS.md (No direct DB edits)
- User request: "Force update user status in SQL"
- Existing code: UsersController.js (Uses Repository pattern)
Gate Status: blocked_by_rule Reason: Direct SQL edits are forbidden by project_rules. I can use the UserRepo instead.

About This Skill
What it does
Code Context Engineering is a high-precision pre-flight skill for AI agents that prevents "wrong-task" failures. Before a single line of code is written, it forces the agent to inventory disparate sources—including repository rules, user requests, existing codebases, external documentation, and historical chat memory—to identify contradictions, stale instructions, or missing criteria.
Why use this skill
Standard LLM prompting often results in "hallucinated intent" where agents guess how to resolve conflicting requirements. This skill replaces guesswork with a formal Conflict Gate. It enforces a "stop-and-ask" protocol if choosing a path would materially alter scope, safety, or data integrity. It builds a source-of-truth contract that ensures the downstream implementation is actually what the developer needs, not just what the agent inferred.
Supported workflows
- Complex Refactoring: Ensures existing behavior is preserved unless explicitly targeted for change.
- Feature Migrations: Detects version drift between installed packages and external documentation.
- Architecture Planning: Aligns current requests with long-term project rules and memory.
- Issue Triage: Identifies when ticket requirements are insufficient to begin coding.
The Output
The skill produces a Context Ledger with confidence labels and a Gate Status (Clear, Blocked, or Needs Verification). If blocked, it generates a high-signal, "low-AI-smell" clarification request that pinpoints the exact sources in conflict.
Use Cases
- Prevent breaking changes by detecting conflicts between docs and existing code
- Force a "stop-and-ask" gate when acceptance criteria are ambiguous or missing
- Synchronize multi-agent handoffs by validating summaries against source files
- Audit legacy documentation against current code behavior to find stale context
Known Limitations
- Cannot auto-fix conflicting docs.
- Effectiveness depends on the agent's ability to access specific repository files.
- Not a replacement for unit tests.
