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 | $0.00085 | $0.00601 |
| Opus 5.5 | $0.00034 | $0.00240 |
| Sonnet 5.5 | $0.00017 | $0.00120 |
| Haiku 4.5 | $0.00009 | $0.00060 |
Grade A, and why
new-sop scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
new-sop
Scaffold a new SOP from a template into the current project. The plugin does not own a global SOPs directory — files are written into the project the user is working in.
Inputs to gather
- Template — one of:
first-aid— clinical procedures (e.g. choking, burns, CPR adjuncts)emergency— incident response (e.g. fire, siren, power outage)household-procedure— routine domestic ops (e.g. monthly inspection, water shutoff)troubleshooting-flow— diagnose-then-act technical proceduresrecipe-method— strict ordered steps with prep / equipment / timing
- Title — short human-readable title.
- Slug — kebab-case filename stem. Default: derived from title.
- Output directory — default
sops/relative to the project root. Create if missing. - Audience (optional) — who's expected to follow this (e.g. "household members", "on-call engineer").
What to do
- Resolve the templates directory: prefer a project-local
templates/sop/<template>.typif present, otherwise fall back to the plugin's bundled template at${CLAUDE_PLUGIN_ROOT}/templates/sop/<template>.typ. - Read the template, substitute frontmatter:
title— from inputrevision—1.0date— today's date in ISO formataudience— from input or omitslug— from input
- Write the result to
<output-dir>/<slug>.typin the current project. - Do NOT compile. The user runs
compileseparately when ready. - Print the path to the new file and a one-line summary of the next sections to fill in.
Templates location
Bundled templates live in ${CLAUDE_PLUGIN_ROOT}/templates/sop/. The user can override per-project by creating templates/sop/<template>.typ in their project — that takes precedence.
Notes
- The user may not have Typst installed yet. This skill only writes source — it doesn't compile.
- If the project has no
sops/directory, create it. - If a file with the same slug already exists, ask before overwriting.
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.

new-sop is a skill published in the GitHub repository danielrosehill/Claude-SOP-Writer-Plugin (3 stars, last pushed 6mo ago), licensed MIT. It adds 85 tokens to every session and 601 once invoked, about $0.0003 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 2026-08-31.
