repo-native-alignment: Skill for Claude Code

.agents/skills/aim/SKILL.md

aim is a skill for Claude Code, Codex from open-horizon-labs/repo-native-alignment. It costs 35 tokens per session (2,049 once invoked), scanned A, original, MIT.

A starting exercise for defining the user behavior you want to change before building anything. It focuses on the desired outcome rather than the feature or technical implementation.

In plain words
What is it for?
Use it at the beginning of a project or when revisiting its purpose. It helps describe what users should do differently after the work is released.
Why use it?
It helps when the scope is unclear, several solutions seem possible, or work has drifted away from its original purpose. This gives the work a clear direction.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is open-horizon-labs/repo-native-alignment's own configuration. It tells Claude Code and Codex how to work on repo-native-alignment 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 repo-native-alignment 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

aim 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 293 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/aim

Clarify the outcome you want. An aim is a change in user behavior, not a feature shipped. This is the first step in the Intent-Execution-Review loop.

The aim IS the abstraction. When you clarify what behavior you want to change, you're abstracting the business domain itself. Features are just the mechanism; the aim is why they matter.

When to Use

Invoke /aim when:

  • Starting new work - Before diving into problem-statement or problem-space
  • Scope feels fuzzy - You can describe what you're building but not why
  • Multiple solutions seem valid - Aim clarifies which one actually moves the needle
  • Work has drifted - Return to aim to check if you're still on track
  • Team is misaligned - Shared aim surfaces hidden assumptions

Do not use when: You already have a crisp aim and need to explore the problem space or solution space. Move to /problem-statement or /problem-space instead.

The Aim Process

Step 1: State the Desired Behavior Change

Start with the user, not the system. What do you want users to do differently after this work ships?

"Users will [specific behavior] instead of [current behavior]."

Bad: "Add dark mode toggle" Good: "Users can work comfortably at night without eye strain"

Bad: "Improve onboarding flow" Good: "New users reach their first value moment within 5 minutes"

Key distinction: Features are outputs. Behavior changes are outcomes.

Step 2: Identify the Mechanism

The mechanism is your hypothesis - the causal lever you believe will produce the behavior change. It's the "because" that connects your work to the outcome.

"This will happen because [mechanism]."

Format:

Mechanism: [What you're changing]
Hypothesis: [Why you believe it will produce the outcome]
Assumptions: [What must be true for this to work]

Step 3: Define the Feedback Signal

How will you know if the aim is achieved? What signal validates or disproves the mechanism?

"We'll know it's working when [observable signal]."

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.

aim is a skill published in the GitHub repository open-horizon-labs/repo-native-alignment (5 stars, last pushed 2d ago), licensed MIT. It adds 35 tokens to every session and 2,049 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
