## Why
The community marketplace audit found many skill frontmatter parse
failures where values were intended as prose, but were not valid YAML.
Common examples include unquoted scalar values with `: `, such as
`description: Build for AWS: ECS` or `argument-hint: <duration: e.g.
7d>`, and flow-looking values such as `tags: [next,@supabase/ssr]`.
`serde_yaml` does not expose a permissive mode for this. The parser
fails before unknown frontmatter fields can be ignored, so a
compatibility repair has to happen before retrying YAML parsing.
## What changed
Skill frontmatter loading still uses `serde_yaml` as the primary parser.
If that parse fails, the loader performs a line-oriented repair of
scalar frontmatter field values, then retries parsing.
The fallback now:
- applies to any frontmatter mapping field, not just `description` /
`short-description`
- quotes unquoted scalar values that contain a YAML colon separator such
as `: `
- quotes invalid flow-looking scalar values that start with `[`, `{`,
`@`, or backtick
- preserves already quoted values
- skips `|` / `>` block scalar bodies so multiline descriptions are not
rewritten
- returns the original YAML error if the repaired frontmatter still
cannot parse
## Examples
This previously failed because the second `: ` was parsed as YAML
structure:
```yaml
description: AWS deployment patterns: ECS Fargate, Lambda, and S3
```
The fallback now parses it as if it had been written explicitly as:
```yaml
description: 'AWS deployment patterns: ECS Fargate, Lambda, and S3'
```
The same repair now applies to ignored frontmatter fields that still
need to be valid YAML for the parser to get through the document:
```yaml
argument-hint: <duration: e.g. 7d, 2w>
tags: [next,@supabase/ssr]
```
Valid YAML multiline descriptions continue to work through normal
parsing without repair:
```yaml
description: |-
Build for AWS: ECS
and Lambda
```
## Validation
- Added loader coverage for unquoted `description` values containing `:
`.
- Added loader coverage for unquoted `metadata.short-description` values
containing `: ` and an apostrophe.
- Added loader coverage for unrecognized frontmatter fields that need
quoting, including `argument-hint` and `tags`.
- Added block-scalar coverage to ensure multiline description bodies are
preserved while other fields are repaired.
- `just test -p codex-core-skills` (106 passed)
- `just fix -p codex-core-skills`

Codex CLI is a coding agent from OpenAI that runs locally on your computer.
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
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
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.
