What it does

Merge Review is an agent skill from SethGammon/Citadel. Reviews pending fleet worktree merges before they're accepted. Reads the merge-check queue, detects file-level conflicts between branches, proposes a safe merge order, and surfaces reconciliation plans for overlapping changes.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `__benchmarks__/empty-queue.md`).

It sits in Business, Finance & HR, covering Git worktrees and Accounting and bookkeeping. The repository describes itself as: The operating layer for Claude Code + OpenAI Codex: persistent project memory, intent routing, safety hooks, cost telemetry, and parallel agent fleets. The licence is MIT.

Example prompts

Workflow steps

8 steps, taken from the step headings in SKILL.md.

Read the Queue
For Each Branch — Gather Diff Data
Detect Overlapping Files
Assess Risk Per Branch
Propose Merge Order
Output the Report
Update the Queue
Cleanup Merged Worktrees

What it can do on your machine

Read from SKILL.md and the folder at commit 2681b89. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Merge Review loads about 1.7k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 676 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~60
When it runs · the whole SKILL.md, loaded when a task matches: ~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

/merge-review — Fleet Merge Arbitration

Orientation

Use when: reviewing pending fleet worktree merges before accepting them into the main branch. Don't use when: reviewing general code quality (use /review); checking CI status before merging (use /pr-watch).

When to Route Here

"check merges"
"any conflicts"
"what do the fleet agents want to merge"
"review the pending branches"
"is it safe to merge fleet output"
"arbitrate the worktrees"
worktree-remove.js has queued items and the user wants to process them

Invocation Forms

/merge-review              # Process the full queue
/merge-review {branch}     # Review a specific branch only

Protocol

Step 1: Read the Queue

Read .planning/telemetry/merge-check-queue.jsonl. Each line is a JSON object:

json

{"branch": "fleet/task-abc", "worktree": "/path/to/worktree", "queuedAt": "ISO"}

If the file doesn't exist or is empty:

"No pending merge reviews. Fleet agents haven't completed any worktrees recently." Stop here.

If invoked with a specific branch (/merge-review {branch}): filter to that branch only.

Step 2: For Each Branch — Gather Diff Data

Run git diff main..{branch} --name-only, --stat, and git branch --list {branch}.

If the branch no longer exists: mark status: "merged", note "likely already merged. Skipped.", continue.

Step 3: Detect Overlapping Files

Compare changed file sets pairwise. For each pair sharing files, read git diff main..{branch} -- {file} for both and classify:

Additive: both add to the file (low risk, likely auto-mergeable)
Overlapping edits: both modify the same function/section (medium risk)
Contradictory: one adds, the other removes the same code (high risk)

Step 4: Assess Risk Per Branch

For each branch:

low — no overlapping files with other branches
medium — overlaps exist but changes appear additive or in different sections
high — overlaps in the same function, class, or closely coupled section

Step 5: Propose Merge Order

Order branches: fewest conflicts first, most conflicts last.

If circular dependencies exist (A conflicts with B, B conflicts with C, C conflicts with A): escalate to the user — do not propose an impossible order.

Step 6: Output the Report

## Merge Review: {N} branch(es) pending

### Branch: {name}
Files changed: {N}
Overlap with other branches: {branch-X} ({file-list}) | none
Risk: low | medium | high
Recommendation: merge | review-first | resolve-conflict

---
[repeat for each branch]
---

### Conflicts Detected

{branch-A} and {branch-B} both modified:
  - {file}: {brief description — e.g., "A adds export, B removes same export"}
Recommended resolution: {which change to keep, or how to combine them}

[repeat for each conflict pair]

### Proposed Merge Order

1. {branch} — no conflicts, safe to merge first
2. {branch} — depends on #1; review {file} after merging #1
3. {branch} — manual conflict resolution needed in {file} before merging

### Summary
Branches ready to merge: {N}
Branches needing review: {N}
Branches with hard conflicts: {N}

If all branches are conflict-free:

## Merge Review: {N} branch(es) pending — No conflicts detected

All branches can be merged in any order. Recommended order (by change size, smallest first):
1. {branch} — {N} files
2. {branch} — {N} files

Step 7: Update the Queue

After producing the report, mark reviewed items in the queue:

Branches still needing work: status: "reviewed", add reviewedAt timestamp
Branches no longer existing: status: "merged" (already handled in Step 2)

Write the updated queue back to .planning/telemetry/merge-check-queue.jsonl.

Step 8: Cleanup Merged Worktrees

Run git worktree list --porcelain. For each non-main worktree: check git branch --merged HEAD. If merged and clean: run git worktree remove "{path}" --force and git branch -d "{branch}". No user confirmation needed. Report count: "Cleaned up {N} merged worktree(s): {branch-names}".

Fringe Cases

Queue empty: Output "No pending merge reviews." and stop.

Branch no longer exists: Remove from queue, note, continue.

Branch not in queue: Note "not in the merge queue" and suggest /merge-review to see all.

All branches conflict (circular): List all conflicts; do not propose an order; escalate to user.

One branch pending: Skip conflict detection; output single-branch review (files, stat, recommendation).

Large diff (>500 lines): Summarize changed areas; link to git diff command for details.

Worktree path missing but branch exists: Proceed with git diff using branch name; worktree existence not required.

Integration Points

worktree-remove.js — queues items to .planning/telemetry/merge-check-queue.jsonl when a fleet worktree completes
fleet skill — run /merge-review after fleet agents complete, before merging to main
session-end.js — may surface a reminder if the merge queue has items at session end

Contextual Gates

Disclosure: "Reviewing pending fleet worktree merges. Read-only — no changes applied." Reversibility: green — read-only review; no files merged or modified Trust gates:

Any: view merge review report and recommendations

Quality Gates

Never merge branches — only analyze and recommend
Always update the queue after processing (mark reviewed/merged)
Always provide a concrete recommendation for each branch (merge / review-first / resolve-conflict)
If a branch was already merged, clean it from the queue without error
If all conflicts are circular/unresolvable, escalate clearly rather than proposing an impossible order

Exit Protocol

/merge-review does not produce a HANDOFF block. It outputs the merge report (Step 6) and then waits for the next user command.

After the report, suggest next actions based on what was found:

If all branches are safe: "All clear. Merge in the order above."
If conflicts exist: "Resolve the flagged conflicts before merging. Run /merge-review again after resolving."
If queue is empty: "Queue is empty. Nothing to review."
