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 | $0.00063 | $0.01629 |
| Opus 5 | $0.00032 | $0.00814 |
| Sonnet 5 | $0.00013 | $0.00326 |
| Haiku 4.5 | $0.00006 | $0.00163 |
Grade A, and why
glean-cli 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 yesterday.
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 — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Glean CLI
glean is a local CLI that authenticates to a company's Glean instance and exposes its REST API. It can search the corporate index, talk to Glean Assistant, look up people, fetch and summarise documents, and manage Glean-side resources (collections, pins, go-links, announcements, curated answers, agents, verification workflows).
Output is JSON on stdout, errors on stderr, exit code reflects success. This makes the CLI ideal for piping into jq.
Prerequisite check
Before using anything in this skill, make sure the binary is on $PATH:
command -v glean
The glean CLI command is provided by brew install gleanwork/tap/glean-cli
If the command isn't found, you shoulkd ask the user if they wish you to install it for them.
If unauthenticated (run glean auth status upon authentication errors) and the user is at a terminal: glean auth login (browser OAuth). For CI or scripts, set GLEAN_API_TOKEN and GLEAN_HOST env vars instead - credentials resolve in the order: env vars -> system keyring -> ~/.glean/config.json.
Always introspect first
glean schema is the source of truth for commands and flags - Glean ships updates, and the schema reflects whatever version is installed locally. Before invoking a command you haven't used in this session, run:
glean schema <command> # full machine-readable schema for one command
glean schema | jq '.commands' # list every available command
The reference file in this skill (references/commands.md) is a fast lookup, but if glean schema disagrees, schema wins.
Calling pattern
glean <command> [subcommand] [flags]
Three flags are global and worth knowing up front:
| Flag | Purpose |
|---|---|
--output <json|ndjson|text> |
Default json. Use ndjson when streaming results to a pipeline. |
--json '<payload>' |
Send a complete JSON request body. Overrides every other flag - use this for any non-trivial request, the schema documents the body shape. |
--dry-run |
Print the request that would be sent, send nothing. Always use this before any create/update/delete operation. |
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.

glean-cli is a skill published in the GitHub repository sammcj/agentic-coding (159 stars, last pushed yesterday), licensed Apache-2.0. It adds 63 tokens to every session and 1,629 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 2026-09-03.
