M3E: Skill for Codex

.agents/skills/kiro-validate-impl/SKILL.md

kiro-validate-impl is a skill for Codex from akaghef/M3E. It costs 31 tokens per session (2,459 once invoked), scanned A, a copy of kiro-validate-impl, MIT.

A validation skill for checking a completed feature across all its implementation tasks. It checks the full test suite, connections between components, requirements coverage, and consistency with the design.

In plain words
What is it for?
Use it after all feature tasks are implemented to validate the feature end to end.
Why use it?
It catches integration problems that individual task reviews can miss, such as mismatched interfaces, missing requirements, or code that does not work together.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: mentions subagents; positional $N argument; 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-validate-impl 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.

Implementation Integration Validation

<background_information> Individual tasks have already been reviewed by the per-task reviewer during implementation. Your job is to catch problems that only become visible when looking across all tasks together.

Boundary terminology continuity:

  • discovery identifies Boundary Candidates

  • design fixes Boundary Commitments

  • tasks constrain execution with _Boundary:_

  • feature validation checks for cross-task Boundary Violations

  • Success Criteria:

    • All tasks marked [x] in tasks.md
    • Full test suite passes (not just per-task tests)
    • Cross-task integration works (data flows between components, interfaces match)
    • Requirements coverage is complete across all tasks (no gaps between tasks)
    • Design structure is reflected end-to-end (not just per-component)
    • No orphaned code, conflicting implementations, integration seams, or boundary spillover

What This Skill Does NOT Do: Per-task checks are the reviewer's responsibility during $kiro-impl. This skill does NOT re-check individual task acceptance criteria, per-file reality checks, or single-task spec alignment.

This skill's main question is: when the completed tasks are viewed together, do they still respect the designed boundary seams and dependency direction? </background_information>

1. Detect Validation Target

If no arguments provided ($1 empty):

  • Parse conversation history for $kiro-impl <feature> [tasks] commands
  • Extract feature names and task numbers from each execution
  • Aggregate all implemented tasks by feature
  • Report detected implementations (e.g., "user-auth: 1.1, 1.2, 1.3")
  • If no history found, scan .kiro/specs/ for features with completed tasks [x]

If feature provided ($1 present, $2 empty):

  • Use specified feature
  • Detect all completed tasks [x] in .kiro/specs/$1/tasks.md

If both feature and tasks provided ($1 and $2 present):

  • Validate specified feature and tasks only (e.g., user-auth 1.1,1.2)

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.
