mergify-merge-protections

mergify-merge-protections is a skill for Claude Code, Codex from Mergifyio/mergify-cli. It costs 142 tokens per session (1,980 once invoked), scanned A, original, Apache-2.0.

A skill for Mergify, a GitHub pull-request automation service, that controls when pull requests may merge. It supports dependencies between pull requests, time-based merge gates, and scheduled freezes.

In plain words
What is it for?
Use it to make one pull request wait for another, delay a merge until a specified time, or pause merges during a scheduled freeze.
Why use it?
It prevents changes from merging before required pull requests, dates, or repository-wide release windows allow them.

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

mergify-merge-protections 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 8d 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.

Mergify Merge Protections

Merge protections control when PRs are allowed to merge:

Protection Scope How
Depends-On Per-PR dependency chain Depends-On: header in PR body
Merge-After Per-PR time gate Merge-After: header in PR body
Scheduled Freezes Repository-wide or conditional CLI commands (mergify freeze)

Depends-On and Merge-After are built-in — just add the header to the PR description (or commit message body when using mergify stack push) and Mergify enforces them automatically, no .mergify.yml configuration needed. Freezes are managed via CLI commands.

Depends-On

Block a PR from merging until one or more other PRs are merged first.

Syntax

Add one or more Depends-On: lines to the PR body:

Depends-On: #123
Depends-On: https://github.com/org/other-repo/pull/456
Depends-On: org/other-repo#789

All three formats are supported — use #NNN for same-repo, full URL or org/repo#NNN for cross-repo.

Rules

  • All referenced PRs must be in repositories with Mergify enabled
  • All referenced PRs must belong to the same GitHub organization
  • Circular dependencies and self-references are silently ignored
  • Multiple Depends-On: lines are allowed (one per line)

With mergify stack push

The stack tool automatically adds Depends-On: #NNN between consecutive PRs in a stack. For dependencies outside the stack (cross-repo or unrelated PRs), add the header manually to the commit message body — it will be copied to the PR description on push.

When to suggest

  • Feature spanning multiple repos (e.g., API change + client update)
  • Schema migration must merge before application code
  • Shared library update must land before consumers

Merge-After

Postpone merging until a specified date and time.

Syntax

Add a Merge-After: line to the PR body:

Merge-After: 2025-09-01T09:00:00Z

Supported timestamp formats (ISO 8601)

Merge-After: 2025-09-01                          # date only (midnight UTC)
Merge-After: 2025-09-01T09:00:00                 # no timezone (assumed UTC)
Merge-After: 2025-09-01T09:00:00Z                # explicit UTC
Merge-After: 2025-09-01T09:00:00+02:00           # with UTC offset
Merge-After: 2025-09-01T09:00:00[Europe/Paris]   # with IANA timezone

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.
