alexsong-oai f959e7fc98 [codex] Emit implicit skill usage for support reads (#29731)
## Summary
- Index all enabled skills for command-based usage detection, regardless
of `allow_implicit_invocation`.
- Preserve `allow_implicit_invocation` for the model-visible implicit
routing list.
- Add regression coverage for a support/preflight skill whose `SKILL.md`
is read and whose script is run while implicit invocation is disabled.

## Root cause
`allow_implicit_invocation` was used for both model routing and
command-based usage-event detection. That meant support skills like
`data-analytics:user-context` could be read or run by other skills, but
those accesses could not emit implicit usage events.

## Validation
- `just fmt`
- `just test -p codex-core-skills
service::tests::skills_for_config_indexes_usage_detection_for_non_implicit_skills`
- `just test -p codex-core-skills` now has the new test passing, but 3
unrelated local tests fail because
`/Users/alexsong/.agents/skills/test/SKILL.md` is invalid/missing YAML
frontmatter.

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

Codex CLI splash


If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.


Quickstart

Installing and running Codex CLI

Run the following on Mac or Linux to install Codex CLI:

curl -fsSL https://chatgpt.com/codex/install.sh | sh

Run the following on Windows to install Codex CLI:

powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"

Codex CLI can also be installed via the following package managers:

# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex

Then simply run codex to get started.

You can also go to the latest GitHub Release and download the appropriate binary for your platform.

Each GitHub Release contains many executables, but in practice, you likely want one of these:

  • macOS
    • Apple Silicon/arm64: codex-aarch64-apple-darwin.tar.gz
    • x86_64 (older Mac hardware): codex-x86_64-apple-darwin.tar.gz
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
