codex-cli-best-practice is a collection of configurations and reusable components for Codex CLI, an agentic coding command-line environment. It organizes commands, subagents, skills, plugins, settings, and hooks to support repeatable coding-agent workflows. The catalogue entries are the project's own Codex extensions and instructions.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00031 | $0.00666 |
| Opus 5.5 | $0.00012 | $0.00266 |
| Sonnet 5.5 | $0.00006 | $0.00133 |
| Haiku 4.5 | $0.00003 | $0.00067 |
Grade A, and why
weather-svg-creator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Weather SVG Creator Skill
This skill creates an SVG weather card from provided temperature data.
Task
Create an SVG weather card displaying the temperature for a given city and write it to the output files.
Instructions
You will receive the temperature value, unit (Celsius or Fahrenheit), and city name from the calling context.
1. Create SVG Weather Card
Generate a clean SVG weather card with the following structure:
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 400 200" width="400" height="200">
<rect width="400" height="200" rx="12" fill="#1a1a2e"/>
<text x="200" y="50" text-anchor="middle" fill="#e0e0e0" font-family="system-ui" font-size="16">[City Name]</text>
<text x="200" y="110" text-anchor="middle" fill="white" font-family="system-ui" font-size="48" font-weight="bold">[value]°[C/F]</text>
<text x="200" y="150" text-anchor="middle" fill="#888" font-family="system-ui" font-size="12">[Current date and time]</text>
<text x="200" y="185" text-anchor="middle" fill="#555" font-family="system-ui" font-size="10">Weather data from Open-Meteo API</text>
</svg>
Replace [value], [C/F], [City Name] with actual values from the input.
2. Write Output Files
Write the SVG content to orchestration-workflow/weather.svg.
Also write a markdown summary to orchestration-workflow/output.md:
# Weather Report
**Location**: [City Name]
**Temperature**: [value]°[C/F]
**Fetched At**: [Current date and time in ISO 8601 format]
> Weather data provided by [Open-Meteo API](https://open-meteo.com/)
- Create the
orchestration-workflow/directory if it does not exist - Overwrite any existing content
Expected Input
Temperature value, unit, and city from the calling agent:
Temperature: [X]°[C/F]
City: [City Name]
Unit: [Celsius/Fahrenheit]
Expected Output
Two files written:
orchestration-workflow/weather.svg— SVG weather cardorchestration-workflow/output.md— Markdown report embedding the SVG
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

weather-svg-creator is a skill published in the GitHub repository shanraisshan/codex-cli-best-practice (1,018 stars, last pushed 4mo ago), licensed MIT. It adds 31 tokens to every session and 666 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
