What is publish-skill?

A workflow for adding or updating skills on an Astro-based website, including preparing the page content and optionally generating its accompanying image.

It is for publishing new skills, refreshing existing skill pages, previewing changes, and optionally skipping image generation.

It removes the repetitive work of locating source files, updating site content, and handling the publishing steps consistently.

publish-skill — Skill for Claude Code and Codex by glebis

Install

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.

Any agent

npx skills add glebis/claude-skills --skill publish-skill

Clone the repo

git clone --depth 1 https://github.com/glebis/claude-skills

Made for: Claude Code, Codex.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 3 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high Rogue Agent · line 3
Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.

Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.

medium Agent Snooping · line 33
Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

Token cost

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	$0.00166	$0.04008
Opus 5	$0.00083	$0.02004
Sonnet 5	$0.00033	$0.00802
Haiku 4.5	$0.00017	$0.00401

Security

Grade A, and why

publish-skill 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 8d 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.

Publish Skill to Site

Automate the full pipeline for publishing a skill to the claude-skills-site Astro website.

Paths

Skills repo: ~/ai_projects/claude-skills/
Site repo: ~/ai_projects/claude-skills-site/
Site skills: ~/ai_projects/claude-skills-site/src/content/skills/*.mdx
Site bundles: ~/ai_projects/claude-skills-site/src/content/bundles/*.mdx

Invocation

/publish-skill <skill-name>              # New skill — generates a hero image by default
/publish-skill <skill-name> --update     # Regenerate existing .mdx (+ hero image)
/publish-skill <skill-name> --dry-run    # Show what would be written, no commits, no image
/publish-skill <skill-name> --no-image   # Skip hero-image generation

Workflow

Execute these phases in order. Stop and report on any error.

Phase 1 — Locate and Read Source

Check ~/ai_projects/claude-skills/<skill-name>/SKILL.md exists. Also check ~/.claude/skills/<skill-name>/SKILL.md.
If neither exists, report error: "SKILL.md not found for <skill-name>. Ensure the skill directory exists in the skills repo or ~/.claude/skills/."
If both exist, compare them. If ~/.claude/skills/ version is newer (by mtime), sync it to the skills repo with rsync -av --exclude='*.egg-info' --exclude='__pycache__', commit the change, and push. This ensures the skills repo always has the latest version.
Read the SKILL.md (preferring the skills repo copy after any sync). Extract:
- name from YAML frontmatter
- description from YAML frontmatter
- Body content (everything after the frontmatter closing ---)
Also check if ~/ai_projects/claude-skills/<skill-name>/README.md exists — if so, read it for supplementary context.

Phase 2 — Check for Existing MDX

Check if ~/ai_projects/claude-skills-site/src/content/skills/<skill-name>.mdx already exists.
If it exists and --update was NOT passed: stop and ask for confirmation. "The skill <skill-name> already has an .mdx on the site. Pass --update to regenerate, or confirm to overwrite."
If it exists and --update was passed: read the existing .mdx. Preserve these fields from the existing file (do not regenerate):
- apothecary_name
- hero_image
- auto_activity
- auto_last_synced (will be updated to today)

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.
