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 | $0.00051 | $0.01254 |
| Opus 5 | $0.00026 | $0.00627 |
| Sonnet 5 | $0.00010 | $0.00251 |
| Haiku 4.5 | $0.00005 | $0.00125 |
Grade A, and why
glab-stack 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 3d 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.

glab stack
Overview
Stacked diffs are a way of creating small changes that build upon each other to ultimately deliver a feature. This
kind of workflow can be used to accelerate development time by continuing to build upon your changes, while earlier
changes in the stack are reviewed and updated based on feedback.
This feature is experimental. It might be broken or removed without any prior notice.
Read more about what experimental features mean at
https://docs.gitlab.com/policy/development_stages_support/
Use experimental features at your own risk.
USAGE
glab stack <command> [command] [--flags]
EXAMPLES
$ glab stack create cool-new-feature
$ glab stack sync
COMMANDS
amend [--flags] Save more changes to a stacked diff. (EXPERIMENTAL)
create Create a new stacked diff. (EXPERIMENTAL)
first Moves to the first diff in the stack. (EXPERIMENTAL)
infer <revision-range> Add layers to a stack based on a range of commits. (EXPERIMENTAL)
last Moves to the last diff in the stack. (EXPERIMENTAL)
list Lists all entries in the stack. (EXPERIMENTAL)
move Moves to any selected entry in the stack. (EXPERIMENTAL)
next Moves to the next diff in the stack. (EXPERIMENTAL)
prev Moves to the previous diff in the stack. (EXPERIMENTAL)
reorder Reorder a stack of merge requests. (EXPERIMENTAL)
save [--flags] Save your progress within a stacked diff. (EXPERIMENTAL)
switch [stack-name] Switch between stacks. (EXPERIMENTAL)
sync Sync and submit progress on a stacked diff. (EXPERIMENTAL)
FLAGS
-h --help Show help for this command.
-R --repo Select another repository. Can use either `OWNER/REPO` or `GROUP/NAMESPACE/REPO` format. Also accepts full URL or Git URL.
Quick start

Current behavior
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.

glab-stack is a skill published in the GitHub repository vince-winkintel/gitlab-cli-skills (46 stars, last pushed 4d ago), licensed MIT. It adds 51 tokens to every session and 1,254 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 2026-08-30.
