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.

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 | $0.00171 | $0.01148 |
| Opus 5 | $0.00086 | $0.00574 |
| Sonnet 5 | $0.00034 | $0.00230 |
| Haiku 4.5 | $0.00017 | $0.00115 |
Grade A, and why
using-glean 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 2d 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Using Glean
The Glean MCP server exposes a family of tools that let the assistant query the user's company knowledge: documents, people, meetings, email, internal code, the user's activity feed, structured memory, and the knowledge graph. This skill is the entry point. It maps a user's question to the right tool, names the rules that apply across all of them, and links to per-tool reference files that carry the deep syntax.
Where these tools live
The tools listed below come from the user's Glean MCP server connection. Refer to them by their bare names (search, employee_search, meeting_lookup, …) — the assistant resolves them against the active tool inventory.
In the raw MCP tool list, Glean tools appear as mcp__glean_[server-name]__[tool] where [server-name] is the user's configured server identifier (e.g., default, production, acme). The tool suffix after the final __ is always consistent across deployments. Use whatever Glean server is visible in your tool inventory.
If no Glean tools are visible, ask the user to set up Glean by prompting the
harness (for example, Set up Glean for me).

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.

using-glean is a skill published in the GitHub repository gleanwork/claude-plugins (25 stars, last pushed 12d ago), licensed MIT. It adds 171 tokens to every session and 1,148 once invoked, about $0.0009 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 2026-08-30.
