Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00022 | $0.00976 |
| Opus 5 | $0.00011 | $0.00488 |
| Sonnet 5 | $0.00004 | $0.00195 |
| Haiku 4.5 | $0.00002 | $0.00098 |
Grade A, and why
optimize-images 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codex Host Adapter
This skill is generated from the canonical Claude Code command named above. To execute it in Codex:
- Treat the text supplied after the skill mention as the invocation arguments. Substitute that exact text for
${CODEX_SKILL_ARGUMENTS}before executing shell commands. - Resolve
CODEX_PLUGIN_ROOTto the absolute plugin root. The loaded skill directory is<plugin-root>/codex-skills/<skill-name>, so the plugin root is two directories above the directory containing thisSKILL.md. - Assign both variables explicitly in any shell call that uses them. Codex does not export these instruction variables automatically.
- Use Codex's available user-input and subagent tools when the workflow requests them.
- Follow the canonical workflow below without skipping its gates or artifact checks.
Canonical Workflow
Image Asset Optimizer
Lossless image optimization with review -> confirm -> apply workflow.
Target: ${CODEX_SKILL_ARGUMENTS} (directory or image file to optimize)
How It Works
Raster images (PNG, JPEG, GIF): Optimizations are fully lossless - file sizes are reduced without any loss in image quality. Uses ImageOptim which applies multiple optimization techniques while preserving every pixel.
SVG files: Uses svgo, the same optimizer powering SVGOMG. The bundled configuration uses web-safe default techniques that safely reduce file size without breaking SVG rendering.
Prerequisites
# Raster images (PNG, JPEG, GIF)
npm install -g imageoptim-cli
# ImageOptim.app required: https://imageoptim.com
# SVG optimization
npm install -g svgo
Workflow (MUST FOLLOW)
Step 1: Optimize and Show Report
Run optimization WITHOUT --cleanup to generate and review results:
CODEX_PLUGIN_ROOT="<absolute plugin root: two directories above the directory containing this SKILL.md>"
"${CODEX_PLUGIN_ROOT}/scripts/optimize-images.sh" "${CODEX_SKILL_ARGUMENTS}" "${CODEX_PLUGIN_ROOT}/scripts/svgo.config.mjs" /tmp/img-optimize
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

optimize-images is a skill published in the GitHub repository vladolaru/claude-code-plugins (8 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 976 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
