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 | $0.00023 | $0.00366 |
| Opus 5 | $0.00012 | $0.00183 |
| Sonnet 5 | $0.00005 | $0.00073 |
| Haiku 4.5 | $0.00002 | $0.00037 |
Grade A, and why
open-pr 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 9d 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
Summarize the latest changes in this branch to create a pull request on GitHub.
- Compare the current branch against the base branch to see what changes need to be described in the pull request. Use the
$baseargument if provided, otherwise the repository's default branch (origin/HEAD):git log "${base:-origin/HEAD}"..HEAD --oneline git diff "${base:-origin/HEAD}"...HEAD
Make sure to only focus on the finalized implementation details. Since pull requests tend to have work-in-progress commits at the beginning, you should be extra mindful on whether these are still relevant in the finalized snapshot.
2. Use the pull request template to generate a .agents/scratchpad/PR.md.
3. Pause here and prompt the user to check the .agents/scratchpad/PR.md before proceeding.
4. Once edited and approved by the user, fill in the missing details in the following script and then run it. With no $base, gh targets the repository's default branch:
gh pr create ${base:+--base "$base"} \
--head "$(git rev-parse --abbrev-ref HEAD)" \
--title '[TICKET-123] category: short title' \
--body-file .agents/scratchpad/PR.md
- Delete
.agents/scratchpad/PR.mdonce successfully submitted.
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.

open-pr is a skill published in the GitHub repository Casper-Studios/casper-marketplace (12 stars, last pushed 5d ago), licensed MPL-2.0. It adds 23 tokens to every session and 366 once invoked, about $0.0001 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.
