M3E: Skill for Codex

.agents/skills/kiro-steering/SKILL.md

kiro-steering is a skill for Codex from akaghef/M3E. It costs 17 tokens per session (1,049 once invoked), scanned A, original, MIT.

A project-knowledge manager for `.kiro/steering/` files. It creates a starting set of documents from a codebase and keeps those documents aligned with later code changes while preserving user-written additions.

In plain words
What is it for?
It is for bootstrapping project guidance, synchronizing it after changes, and maintaining shared architectural knowledge.
Why use it?
It gives an agent a persistent description of a project's purpose, technology, and structure instead of relying only on the current conversation. It can also reveal when the documentation has drifted from the code.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: mentions subagents; installed under .agents/ (shared by several agents).

This is akaghef/M3E's own configuration. It tells Codex how to work on M3E itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything M3E configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

kiro-steering scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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):
Parallel Research

The following research areas are independent and can be executed in parallel:

  1. Product analysis: README, package.json, documentation files for purpose, value, core capabilities
  2. Tech analysis: Config files, dependencies, frameworks for technology patterns and decisions
  3. Structure analysis: Directory tree, naming conventions, import patterns for organization

If multi-agent is enabled, spawn sub-agents for each area above. Otherwise execute sequentially.

After all parallel research completes, synthesize patterns for steering files.

  1. Extract patterns (not lists):
    • Product: Purpose, value, core capabilities
    • Tech: Frameworks, decisions, conventions
    • Structure: Organization, naming, imports
  2. Generate steering files (follow templates)
  3. Load principles from rules/steering-principles.md from this skill's directory
  4. 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

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
