Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00007 | $0.00273 |
| Opus 5.5 | $0.00003 | $0.00109 |
| Sonnet 5.5 | $0.00001 | $0.00055 |
| Haiku 4.5 | $0.00001 | $0.00027 |
Grade A, and why
install scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Install plugin-cache-sync
Install the plugin-cache-sync CLI to ~/.local/bin so it's available globally.
Execution
Run all steps below in order.
Step 1: Install for the platform
mkdir -p ~/.local/bin
On Linux and macOS, symlink the script:
ln -sf "${CLAUDE_PLUGIN_ROOT}/scripts/plugin-cache-sync" ~/.local/bin/plugin-cache-sync
On Windows (Git Bash, MSYS2, Cygwin), copy it instead:
cp -f "${CLAUDE_PLUGIN_ROOT}/scripts/plugin-cache-sync" ~/.local/bin/plugin-cache-sync && chmod +x ~/.local/bin/plugin-cache-sync
Step 2: Confirm
plugin-cache-sync version
When the shell reports command not found, ~/.local/bin is not in PATH.
Tell the user to add export PATH="$HOME/.local/bin:$PATH" to their shell profile.
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.

install is a command published in the GitHub repository bengous/claude-code-plugins (5 stars, last pushed today), licensed MIT. It adds 7 tokens to every session and 273 once invoked, about $0.0000 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 2026-09-03.

land
Resolve and squash merge one named, currently authorized pull request.
sync
Manually trigger plan-sync to update downstream task specs after implementation drift.
