Kiro Steering Management

<background_information> Role: Maintain .kiro/steering/ as persistent project memory.

Mission:

• Bootstrap: Generate core steering from codebase (first-time)
• Sync: Keep steering and codebase aligned (maintenance)
• Preserve: User customizations are sacred, updates are additive

Success Criteria:

• Steering captures patterns and principles, not exhaustive lists
• Code drift detected and reported
• All .kiro/steering/*.md treated equally (core + custom) </background_information>

Check .kiro/steering/ status:

Bootstrap Mode: Empty OR missing core files (product.md, tech.md, structure.md)
Sync Mode: All core files exist

Bootstrap Flow

1. Load templates from .kiro/settings/templates/steering/
2. Analyze codebase (JIT):
   • glob_file_search for source files
   • read_file for README, package.json, etc.
   • grep for patterns
3. Extract patterns (not lists):
   • Product: Purpose, value, core capabilities
   • Tech: Frameworks, decisions, conventions
   • Structure: Organization, naming, imports
4. Generate steering files (follow templates)
5. Load principles from .kiro/settings/rules/steering-principles.md
6. Present summary for review

Focus: Patterns that guide decisions, not catalogs of files/dependencies.

Sync Flow

1. Load all existing steering (.kiro/steering/*.md)
2. Analyze codebase for changes (JIT)
3. Detect drift:
   • Steering → Code: Missing elements → Warning
   • Code → Steering: New patterns → Update candidate
   • Custom files: Check relevance
4. Propose updates (additive, preserve user content)
5. Report: Updates, warnings, recommendations

Update Philosophy: Add, don't replace. Preserve user sections.

Granularity Principle

From .kiro/settings/rules/steering-principles.md:

"If new code follows existing patterns, steering shouldn't need updating."

Document patterns and principles, not exhaustive lists.

Bad: List every file in directory tree
Good: Describe organization pattern with examples

Tool guidance

• glob_file_search: Find source/config files
• read_file: Read steering, docs, configs
• grep: Search patterns
• list_dir: Analyze structure

JIT Strategy: Fetch when needed, not upfront.

Output description

Chat summary only (files updated directly).

Bootstrap:

✅ Steering Created

## Generated:
- product.md: [Brief description]
- tech.md: [Key stack]
- structure.md: [Organization]

Review and approve as Source of Truth.

Sync:

✅ Steering Updated

## Changes:
- tech.md: React 18 → 19
- structure.md: Added API pattern

## Code Drift:
- Components not following import conventions

## Recommendations:
- Consider api-standards.md

Examples

Bootstrap

Input: Empty steering, React TypeScript project
Output: 3 files with patterns - "Feature-first", "TypeScript strict", "React 19"

Sync

Input: Existing steering, new /api directory
Output: Updated structure.md, flagged non-compliant files, suggested api-standards.md

Safety & Fallback

• Security: Never include keys, passwords, secrets (see principles)
• Uncertainty: Report both states, ask user
• Preservation: Add rather than replace when in doubt

Notes

• All .kiro/steering/*.md loaded as project memory
• Templates and principles are external for customization
• Focus on patterns, not catalogs
• "Golden Rule": New code following patterns shouldn't require steering updates
• Avoid documenting agent-specific tooling directories (e.g. .cursor/, .gemini/, .claude/)
• .kiro/settings/ content should NOT be documented in steering files (settings are metadata, not project knowledge)
• Light references to .kiro/specs/ and .kiro/steering/ are acceptable; avoid other .kiro/ directories
