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.

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 | $0.00032 | $0.00301 |
| Opus 5.5 | $0.00013 | $0.00120 |
| Sonnet 5.5 | $0.00006 | $0.00060 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
skill-sync scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Skill Sync
Manage skills from the shared GitHub repository with GitHub as canonical source of truth.
Never commit secrets. Keep keys/tokens out of SKILL.md and scripts.
Quick Reference
# List available skills in the repo
skill-sync list
# Install one skill
skill-sync install <skill-name>
# Install/update all skills from repo
skill-sync install --all
# Push a local skill update to repo via PR
skill-sync push <skill-name>
# Refresh local repo cache
skill-sync update
Commands
skill-sync list
Shows all skills available in the remote repository.
skill-sync install <name>
Installs/updates a skill from repo into local skills directory.
skill-sync install --all
Installs/updates all skills from repo.
skill-sync push <name>
Pushes local skill changes via branch + PR (gh CLI).
skill-sync update
Pulls latest repo changes without installing.
Configuration
Default paths:
- Repo clone:
~/.agent-skills-repo - Local skills:
~/clawd/skills(or$CLAWD_SKILLS_DIR) - Remote:
https://github.com/jdrhyne/agent-skills.git
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.
