Use this skill

Save it into your project's skills folder. Claude Code picks it up in its next session.

curl -fsSL --create-dirs -o .claude/skills/umputun-ask-codex/SKILL.md https://app.decimal.ai/s/umputun-ask-codex/SKILL.md

Want it pinned and updatable? pip install "decimalai>=0.15", then decimalai skills add umputun-ask-codex, and start Claude Code with claude --plugin-dir "$(git rev-parse --show-toplevel)/.agents"

1 · One-time — install the CLI (docs ↗)

pip install "decimalai>=0.15"

2 · Get the skill — writes .agents/skills/umputun-ask-codex/ and pins it in .decimal/skills.lock

One of 7 test cases the skill fixed. Same model, same prompt, with and without the skill.

Prompt

When preparing context for Codex regarding an issue spanning `pkg/store/db.go` and `pkg/store/cache.go`, should full file contents be dumped into the prompt?

What was checked, without and with the skill
Checked	Without skill	With skill
Provides exact file paths and line number references instead of dumping full file contents	Missed	Passed

Ask Codex

Consult OpenAI Codex (GPT-5.5) as a second opinion for investigation, debugging, or review tasks.

Activation Triggers

Explicit:

"ask codex", "check with codex", "codex review"
"what does codex think", "get codex opinion"
"consult codex", "run codex on this"

Automatic (last resort — stuck detection):

4+ failed attempts at the same bug fix or investigation
completely out of ideas, all reasonable approaches exhausted
going in circles with no progress despite multiple different strategies

Workflow

Step 1: Check Availability

Run which codex to verify the CLI is installed. If not found, inform the user and stop.

Step 2: Build Context

Gather context from the current conversation:

What's the problem/question — summarize in 2-3 sentences
What we know — relevant files, error messages, behavior observed
What we tried — approaches attempted and why they failed (if applicable)
Specific question — what exactly codex should analyze or answer

Codex does NOT auto-load Claude Code's memory files — it only reads AGENTS.md. To give Codex the same project context Claude follows, prepend the memory-load preamble described in Step 3.

Step 3: Construct Prompt

Build a focused prompt. Do NOT dump entire files — codex has full project access and can read them itself. Provide file paths and line references so codex knows where to look.

Prepend a memory-load preamble. Codex auto-loads only AGENTS.md; it does NOT read Claude Code's memory files (CLAUDE.md, CLAUDE.local.md, .claude/rules/, ~/.claude/CLAUDE.md), so the project conventions Claude follows are invisible to Codex unless you tell it to read them. Prepend this line to the prompt:
