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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.02664 |
| Opus 5 | $0.00009 | $0.01332 |
| Sonnet 5 | $0.00004 | $0.00533 |
| Haiku 4.5 | $0.00002 | $0.00266 |
Grade A, and why
oh-merge 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 12d 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 — 290 lines — stays where its author put it; the contents beside it link to each section on GitHub.
oh-merge
Holistically review pending GitHub issue PRs from oh-task, then squash-merge them as a cohesive batch.
Invocation
/oh-merge
Flow
-
Load project background from
AGENTS.md, relevant.oh/artifacts, and RNA MCP context when available. -
Find all PRs with
oh-mergelabel:gh pr list --label oh-merge --json number,title,headRefName,baseRefName,additions,deletionsOnly PRs with the
oh-mergelabel are eligible for merge.IMPORTANT: PRs with merge conflicts ARE eligible. The skill rebases and resolves conflicts in step 6. Do NOT skip PRs because of conflict status - that's exactly what this skill handles.
-
Build dependency graph and identify stacks:
-
Create adjacency list:
baseRefName → [PRs targeting it] -
Find root PRs: those where
baseRefName = main(or master) -
Identify stacks: chains where child PRs target parent PR branches
-
Detect cycles: If a branch eventually targets itself, report error and skip
-
Example graph:
main ← PR #42 (issue/123) ← PR #43 (issue/456) main ← PR #44 (issue/789) [separate stack]
-
-
Select stack to process:
- If multiple independent stacks exist, pick first by lowest root PR number (FIFO by age)
- If multiple PRs target the same base branch, order by PR number (lowest first)
- Report other stacks as "queued for next run"
- Process only one stack per invocation to keep merges atomic
- Orphaned children: If a child PR targets a branch that doesn't exist (parent merged externally), update its base to main and treat as a root
-
Batch review - evaluate all PRs in the selected stack together:
- Collect combined diff of all PRs against main
- Run the repo-local
/reviewskill on the combined changes - Evaluate:
- Do changes conflict logically? (same code modified differently)
- Is there duplicate work? (two PRs solving same problem)
- Do changes compose well? (feature A + feature B = coherent whole)
- Any cross-cutting concerns? (shared dependencies, API changes)
- If concerns found:
- Report issues
- Ask human whether to proceed or address first
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-merge is a skill published in the GitHub repository open-horizon-labs/repo-native-alignment (5 stars, last pushed 4d ago), licensed MIT. It adds 18 tokens to every session and 2,664 once invoked, about $0.0001 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.
