Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00152 | $0.02834 |
| Opus 5.5 | $0.00061 | $0.01134 |
| Sonnet 5.5 | $0.00030 | $0.00567 |
| Haiku 4.5 | $0.00015 | $0.00283 |
Grade A, and why
arn-code-batch-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 1mo 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 — 261 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Arness Batch Merge
Smart PR management dashboard with guided per-PR review. Discover open batch PRs, delegate cross-PR analysis, then drive an interactive review/merge/refresh cycle.
This skill is a sequencer. It MUST NOT duplicate sub-skill logic. Arness-code-batch-merge handles: PR discovery, cross-PR analysis delegation, interactive review loop, merge execution, Feature Tracker updates, and chaining. Review logic lives in arn-code-review-pr; analysis logic lives in the arn-code-batch-pr-analyzer agent.
Pipeline position:
arn-code-batch-implement -> **arn-code-batch-merge** -> arn-code-batch-simplify
|
+-- per PR: review-pr -> approve/merge -> refresh
Step 0: Ensure Configuration
Read ${CLAUDE_PLUGIN_ROOT}/skills/arn-code-ensure-config/references/step-0-fast-path.md and follow its instructions. This guarantees a user profile exists and ## Arness is configured with Arness Code fields before proceeding.
After configuration is ensured, extract the following from ## Arness:
- Plans directory -- base path where project plans and CHANGE_RECORD.json files are stored
- Platform --
github,bitbucket, ornone - Vision directory (if exists) -- path containing the feature backlog
- Code patterns (if exists) -- path to code patterns directory
Step 1: Discover Batch PRs (Lightweight)
Platform Gate
If Platform is none: "Batch merge requires a platform (GitHub or Bitbucket) for PR management. Merge branches manually." STOP.
If Platform is github: verify gh CLI is available. If not: "The GitHub CLI (gh) is required for batch merge. Install it from https://cli.github.com/ and authenticate with gh auth login." STOP.
If Platform is bitbucket: verify bkt CLI is available. If not: "The Bitbucket CLI (bkt) is required for batch merge." STOP.
Scan for Batch PRs
Scan the Plans directory for CHANGE_RECORD.json files. Check all plan subdirectories: */CHANGE_RECORD.json, STANDARD_*/CHANGE_RECORD.json, SWIFT_*/CHANGE_RECORD.json.
What ships with it
1 file 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.
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.

arn-code-batch-merge is a skill published in the GitHub repository AppsVortex/arness (33 stars, last pushed 2mo ago), licensed MIT. It adds 152 tokens to every session and 2,834 once invoked, about $0.0006 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 2026-08-30.
Other skills, from other repositories
upstream-patches
Create, amend, remove, and rebase patches for Terraform provider submodules using ./scripts/upstream.sh. Use when upgrade-provider or manual patch work needs owning-patch lookup, patch conflict fixes, patch/hunk removal, or upstream rebase.
resolve-conflicts
Use this skill immediately when the user mentions merge conflicts that need to be resolved. Do not attempt to resolve conflicts directly - invoke this skill first. This skill specializes in providing a structured framework for merging imports, tests, lock files (regeneration), configuration files, and handling…
update-pr
Update an existing pull request with new changes. Use when the user wants to update a PR, push follow-up changes to a PR, refresh a PR description, or sync a PR with latest commits. Triggers on: update pr, update-pr, update the pr, push to pr, refresh pr, sync pr, update pull request.
smart-rebase
Smart partial rebase for squash-merge repositories. Auto-detect which commits to keep/drop when base branch was squash-merged into target. Use when: user says 'rebase', 'partial rebase', 'base already merged', 'smart rebase', or /smart-rebase. Not for: simple git rebase (the developer runs it — no skill executes…
next-step
Change-aware next step advisor. Use when: user asks what to do next, workflow progression is unclear, session just started with dirty worktree. Not for: executing the suggested command (user decides), auto-loop decisions (hooks handle that). Output: findings-based suggestions or session summary with commit seed.
merge-prep
Pre-merge analysis and preparation. Analyzes source branch vs target branch: commit stats, conflict detection, file impact. Analysis-only v1 — outputs report + suggested commands, does not auto-merge. Use when: user says 'merge prep', 'pre-merge', 'merge analysis', or /merge-prep.
