What it does

Codex PR is an agent skill from tbhb/vale-ai-tells. Open or update a pull request for the current branch with an independently drafted and reviewed PRAGENTDESC.md. Use whenever the user asks Codex to open or draft a pull request in a tbhb repository, or when a completed task should end in a pull request. Routes later CI work to codex-watch-pr and codex-fix-pr.

Its SKILL.md is about 850 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts (for example `scripts/create-pr.sh`, `scripts/preflight.sh` and `scripts/record-review.sh`).

It sits in Development, covering Pull requests. The repository describes itself as: In today's rapidly evolving landscape, vale-ai-tells is a comprehensive, cutting-edge Vale style package that empowers writers to seamlessly delve into the rich tapestry of AI…. The licence is MIT.

When your agent uses it

  • The user asks Codex to open
  • Draft a pull request in a tbhb repository
  • A completed task should end in a pull request

Example prompts

  • “/codex-pr”

Requirements

  • A Bash shell

What it can do on your machine

Read from SKILL.md and the folder at commit 4c7abc9. 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

    Ships 5 files in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • mise
    • bash
    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use gh, 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

Codex PR loads about 846 tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 369 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~80
When it runs · the whole SKILL.md, loaded when a task matches
~846

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); the scripts in this folder are not scanned.

description
Open or update a pull request for the current branch with an independently drafted and reviewed PR_AGENTDESC.md. Use whenever the user asks Codex to open or draft a pull request in a tbhb repository, or when a completed task should end in a pull request. Routes later CI work to codex-watch-pr and codex-fix-pr.

Open a pull request

Use update_plan for these phases: preflight, draft, prose gates, independent review, confirmation, publication, and requested follow-through. Keep only one phase in_progress.

Preflight

Run:

bash
bash .agents/skills/codex-pr/scripts/preflight.sh

Stop on a missing prerequisite or an interrupted Git operation. If the branch is behind its base, use codex-rebase first. Tell the user about uncommitted changes before continuing. The preflight scaffolds PR_AGENTDESC.md and reports an existing pull request.

Draft with a delegated writer

Spawn one subagent with this bounded task:

text
Use the codex-write-pr-description skill in <repo root>. Write or revise PR_AGENTDESC.md, run its validator, and return only its DRAFT result.

Don't draft the file in the calling context. If the writer reports DRAFT: BLOCKED, report the blocker and stop.

Run the prose workflow over PR_AGENTDESC.md with mise run lint-pr-description when codex-fix-prose is available. Otherwise run that task directly and resolve only mechanical findings.

Review with a fresh delegated agent

Spawn a different subagent:

text
Use the codex-review-pr-description skill in <repo root>. Review PR_AGENTDESC.md against the branch and return its verdict.

On CHANGES REQUIRED, send the findings verbatim to a fresh writer, then review again with a fresh reviewer. Bound finding-driven revisions at three. After PASS, the reviewer records the reviewed digest through record-review.sh. Don't run that script from the calling agent.

Run mise run lint-pr-description after review. Any edit invalidates the digest, so repeat the independent review after a change.

Get confirmation in default mode

Show the branch, base, commit count, and complete draft. Unless preflight reports pr: GRANTED, ask before publication by putting this question and its choices in the final response when using Default mode:

  • open, fix, and merge
  • open, watch, and fix
  • open and watch
  • open only

Also ask whether fixes should be separate commits or amendments. A pre-approval chooses separate commits and routes through merge only when merge: GRANTED. Stop there: don't publish in the turn that asks for confirmation.

Publish

After confirmation, run only:

bash
bash .agents/skills/codex-pr/scripts/create-pr.sh

The script checks the draft and requires the recorded digest to match its current bytes. It also resolves properties, pushes, and creates or updates the pull request. Don't bypass it with a direct mutating gh pr call. Report the URL.

Route follow-through to codex-watch-pr and codex-fix-pr according to the confirmed choice. Bound repeated fixes of the same check at three. Use codex-merge-pr only when the user explicitly requested merging or pre-approved it.
