repo-native-alignment: Skill for Claude Code

.agents/skills/oh-join/SKILL.md

oh-join is a skill for Claude Code, Codex from open-horizon-labs/repo-native-alignment. It costs 23 tokens per session (1,341 once invoked), scanned A, original, MIT.

A workflow for combining several dependent GitHub pull requests into one shared starting branch.

In plain words
What is it for?
Use it to find dependency issues and their open pull requests, verify they are ready, merge them in a fixed order, and update the target issue's dependencies.
Why use it?
It addresses cases where an issue depends on two or more changes and the normal scheduler cannot place them into a single branch stack.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents; 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

oh-join 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 2mo 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 — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.

oh-join

Use this skill when an issue has 2+ open dependencies and scheduler cannot auto-stack because there is no single base branch.

Invocation

/oh-join <issue-number>

  • <issue-number>: target GitHub issue (for example 1178 or #1178)

Goal

For target issue #X:

  1. Read Depends on: dependencies
  2. Find linked open PRs for those dependency issues
  3. Verify dependency PRs are ready to merge
  4. Merge them into one common base branch in deterministic order
  5. Update target issue dependencies to reflect merged deps
  6. Signal completion with outcome details

Flow

  1. Load issue and dependencies

    gh issue view <issue-number> --json number,title,body,state,url
    • Parse all dependency numbers from Depends on: lines.
    • If fewer than 2 dependencies: stop with blocked (not a join case).

  2. Discover open PRs for dependency issues

    gh pr list --state open --json number,title,headRefName,baseRefName,body,url
    • Map dependency issue number -> linked PR by either:
      • branch pattern issue/<N> or issue-<N>
      • PR body containing Closes #N / Fixes #N / Resolves #N
    • If any dependency has no open PR: stop with blocked and list missing deps.

  3. Determine common base branch

    • Collect baseRefName across dependency PRs.
    • If all same: that is the common base branch.
    • If different:
      • Attempt to find shared upstream branch by checking whether all base branches descend from a common candidate.
      • If no safe common base is found, stop with blocked and report conflicting bases.

  4. Readiness checks for each dependency PR For each dep PR:

    gh pr checks <pr-number> --fail-on-error
gh pr view <pr-number> --json reviewDecision,isDraft,mergeable
    • Must not be draft
    • Must be mergeable
    • CI checks must pass
    • Review decision must not be CHANGES_REQUESTED
    • The complete repository /ship pipeline must be evidenced on the final commit
    • Every PR must have an explicit APPROVE from a fresh, separate repo-local /review sub-agent for the exact final commit
    • Any diff change after that approval invalidates it and requires a new fresh reviewer
    • CodeRabbit is optional supplemental feedback: never trigger or wait for it, but verify any actionable comments already present were addressed If any fail: stop with blocked and report specific PR reasons.

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.

oh-join is a skill published in the GitHub repository open-horizon-labs/repo-native-alignment (6 stars, last pushed 1mo ago), licensed MIT. It adds 23 tokens to every session and 1,341 once invoked, about $0.0001 per session on Opus 5.5. 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.
