What it does

PR Fixer is an agent skill from ambient-code/platform. Trigger the Amber Handler to automatically fix a pull request (rebase, address review comments, run lints/tests, push fixes). Posts @ambient-code on the PR to trigger the fix prompt. Use when user types /pr-fixer <number, says "fix PR", "run pr-fixer", "address PR comments", or "auto-fix pull request".

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `evals/evals.json`).

It sits in Development, covering Linting and formatting and Pull requests. The repository describes itself as: Vision/Mission https://ambient-code.ai : Virtual team management and collaboration platform. User guides: https://ambient-code.github.io/platform/. The licence is MIT.

When your agent uses it

  • The Amber Handler to automatically fix a pull request (rebase
  • Address review comments
  • Run lints/tests
  • User types /pr-fixer <number

Example prompts

  • “fix PR”
  • “run pr-fixer”
  • “address PR comments”
  • “/pr-fixer”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Validate prerequisites
  2. Pre-flight PR check
  3. Trigger the fix
  4. Locate the triggered run
  5. Print the run URL immediately so the user has it
  6. Spawn a background agent to monitor the run (30-minute timeout)

What it can do on your machine

Read from SKILL.md and the folder at commit e15afd3. 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:

    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    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

PR Fixer loads about 1k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 488 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~1k

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.

description
Trigger the Amber Handler to automatically fix a pull request (rebase, address review comments, run lints/tests, push fixes). Posts @ambient-code on the PR to trigger the fix prompt. Use when user types /pr-fixer <number>, says "fix PR", "run pr-fixer", "address PR comments", or "auto-fix pull request".

PR Fixer Skill

Triggers the Amber Handler (amber-issue-handler.yml) to automatically fix a pull request. Posting @ambient-code on a PR triggers the fix prompt, which creates an ACP session that rebases the PR, evaluates reviewer comments (fixes valid issues, responds to invalid ones), runs lints and tests, and pushes the fixes.

Usage

/pr-fixer <pr-number>

The PR number is required. Example: /pr-fixer 1234

What It Does

  1. Validate prerequisites

    • Confirm gh CLI is authenticated (gh auth status)
    • Detect the repo from the local git remote (gh repo view --json nameWithOwner --jq .nameWithOwner)

  2. Pre-flight PR check

    • Check the PR exists and its state:
      bash
      gh pr view <N> --repo <owner/repo> --json state,isCrossRepository --jq '{state, isCrossRepository}'
    • gh pr view returns state in uppercase: OPEN, CLOSED, or MERGED. A non-zero exit code (with stderr error) means the PR does not exist.
    • If the exit code is non-zero: abort with "PR #N not found in <owner/repo>."
    • If state is CLOSED or MERGED: abort with "PR #N is already <state>. Nothing to fix." (use the actual uppercase value returned)
    • Only proceed if state is exactly OPEN.
    • If PR is from a fork (isCrossRepository: true), warn: "PR #N is from a fork. The Amber Handler skips fork PRs. Push the branch to the org repo and re-open the PR, or fix locally."

  3. Trigger the fix

    bash
    gh pr comment <N> --repo <owner/repo> --body "@ambient-code"

  4. Locate the triggered run

    • Wait a few seconds for the run to register
    • Find it via:
      bash
      gh run list --workflow=amber-issue-handler.yml --repo <owner/repo> --limit 5 --json databaseId,status,createdAt,event
    • Match the most recent issue_comment-triggered run created after the comment

  5. Print the run URL immediately so the user has it:

    PR Fixer dispatched for PR #<N>
Run: https://github.com/<owner/repo>/actions/runs/<run-id>
PR:  https://github.com/<owner/repo>/pull/<N>

Monitoring in background — you'll be notified when it completes.

  6. Spawn a background agent to monitor the run (30-minute timeout):

    • Poll gh run view <run-id> --repo <owner/repo> --json status,conclusion every 30 seconds
    • If 30 minutes elapse without completion, notify: "PR Fixer timed out after 30 minutes. Check the run manually."
    • When the run reaches a terminal state, notify with:
      • Run conclusion (success/failure/cancelled)
      • Session name and phase (parse from gh run view <run-id> --repo <owner/repo> --json jobs — look for the "Session summary" step output)
      • Whether commits were pushed (check gh pr view <N> --repo <owner/repo> --json commits count before and after)
      • Links to the GHA run and the PR

Error Handling

  • No PR number provided: Print usage: /pr-fixer <pr-number>
  • gh not authenticated: "Error: GitHub CLI is not authenticated. Run gh auth login first."
  • Fork PR detected: "Warning: PR #N is from a fork. The Amber Handler skips fork PRs. Push the branch to the org repo and re-open the PR, or fix locally."
  • Run not found after dispatch: "Warning: Could not locate the triggered run. Check manually: https://github.com/<owner/repo>/actions/workflows/amber-issue-handler.yml"
  • All session steps skipped: The Amber Handler's fix steps have conditions (non-fork, correct prompt type). If steps are skipped, check the run logs for why.

When to Invoke This Skill

Invoke when users say things like:

  • "/pr-fixer 1234"
  • "Fix PR 1234"
  • "Run the PR fixer on 1234"
  • "Trigger pr-fixer for PR #1234"
