Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00067 | $0.01142 |
| Opus 5 | $0.00034 | $0.00571 |
| Sonnet 5 | $0.00013 | $0.00228 |
| Haiku 4.5 | $0.00007 | $0.00114 |
Grade A, and why
skills-sync-bootstrap scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skills Sync Bootstrap
Use this skill to set up skills-sync on the current device. The sync tool is intentionally not authoritative about local agent layouts; this skill makes the device-local agent inspect the filesystem, write an explicit config, and report what was included or ignored.
Workflow
- Locate the CLI:
command -v skills-sync
If skills-sync is not on PATH, use the repo-local CLI path when present:
node ./bin/skills-sync.js <command>
When scripting fallback usage, store the path and keep node separate:
SKILLS_SYNC_CLI=${SKILLS_SYNC_CLI:-"$PWD/bin/skills-sync.js"}
node "$SKILLS_SYNC_CLI" probe --json
- Probe the machine:
skills-sync probe --json
The probe emits facts only: candidate paths, existence, SKILL.md counts, and hard avoid patterns. Do not treat probe candidates as automatically correct.
- Write config explicitly. Prefer:
~/.skills-sync/config.json
~/.skills-sync/state/ # state dir
~/.skills-sync/skills-monorepo/ # audit repo
Config shape:
{
"sourceRoots": [
{ "path": "~/.codex/skills", "sourceSystem": "codex-skills", "tier": "live", "depth": 1 }
],
"monorepo": { "path": "~/.skills-sync/skills-monorepo" },
"review": { "mode": "manual" },
"ingest": { "enabled": false, "command": "" },
"watch": { "intervalSeconds": 2, "ignore": [] }
}
- Validate and initialize:
skills-sync config validate --config ~/.skills-sync/config.json
skills-sync init --config ~/.skills-sync/config.json --state-dir ~/.skills-sync/state --monorepo ~/.skills-sync/skills-monorepo
- Run the archive bootstrap:
skills-sync snapshot --config ~/.skills-sync/config.json --state-dir ~/.skills-sync/state --monorepo ~/.skills-sync/skills-monorepo
skills-sync bootstrap --config ~/.skills-sync/config.json --state-dir ~/.skills-sync/state --monorepo ~/.skills-sync/skills-monorepo --json
- Report included roots, missing roots, ignored roots, snapshot skill count, bootstrap commit, and ingest status. Ingest should normally be
skippedunless explicitly configured.
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.

skills-sync-bootstrap is a skill published in the GitHub repository 1va7/skills-sync (5 stars, last pushed 1mo ago), licensed MIT. It adds 67 tokens to every session and 1,142 once invoked, about $0.0003 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.
