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 | $0.00544 |
| Opus 5.5 | $0.00013 | $0.00218 |
| Sonnet 5.5 | $0.00006 | $0.00109 |
| Haiku 4.5 | $0.00003 | $0.00054 |
Grade A, and why
sync-client-libs 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
Sync Client Libraries Skill
Use this skill to automatically discover, verify, and update all Google Ads client libraries located in client_libs/ against their latest upstream releases on GitHub.
Overview
The client library sync tool inspects each codebase under client_libs/ (e.g., google-ads-python, google-ads-php, google-ads-ruby, google-ads-java, google-ads-dotnet), determines the locally installed release version, fetches the latest release tag from GitHub, and automatically synchronizes the codebase if the local installation is outdated.
CLI Usage
Check / Dry-Run (No modifications)
python3 skills/sync-client-libs/scripts/sync_client_libs.py --check_only
Automated Update
python3 skills/sync-client-libs/scripts/sync_client_libs.py
Output Structured JSON
python3 skills/sync-client-libs/scripts/sync_client_libs.py --json
Options Reference
| Flag | Short | Description |
|---|---|---|
--check_only |
--dry_run |
Check versions and report status without modifying any files. |
--force |
Force re-syncing/updating codebases even if versions match. | |
--client_libs_dir |
-d |
Explicit path to client_libs directory (auto-detected if omitted). |
--library |
-l |
Filter to target a specific library (e.g. google-ads-python). |
--json |
Output results in JSON format for automated ingestion. |

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.

sync-client-libs is a skill published in the GitHub repository googleads/google-ads-api-developer-assistant (102 stars, last pushed 8d ago), licensed Apache-2.0. It adds 32 tokens to every session and 544 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.
