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 5.1 | $0.00049 | $0.01070 |
| Opus 5.5 | $0.00020 | $0.00428 |
| Sonnet 5.5 | $0.00010 | $0.00214 |
| Haiku 4.5 | $0.00005 | $0.00107 |
Grade A, and why
diff-remove 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 1mo 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 — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.
What This Command Does
In plain English: Undo a DexDiff adoption. Removes the skills, CLAUDE.md sections, and templates that were created when you adopted a workflow. Your data (meeting notes, people pages, etc.) is never deleted.
When to use it:
- You adopted a workflow and want to remove it
- You want to clean up before re-adopting an updated version
How to run it:
/diff-remove meeting-prep
/diff-remove
Arguments
$ARGUMENTS — The diff ID of the workflow to remove. This is the id field from the methodology YAML, logged during adoption.
If no argument is provided, list all installed diffs and let the user pick:
You have these adopted workflows:
meeting-prep — "Meeting Prep Ritual" (adopted 2026-03-28)
deal-review — "Deal Review Ritual" (adopted 2026-03-25)
Which one would you like to remove?
To get the list, read all JSON files in both adoption locations:
.dex/adoptions/- single-workflow adoptions from/diff-adoptSystem/.dex/adoptions/profiles/- whole-profile adoptions from/diff-adopt-profile(these are profile-level records; removing one means removing the skills generated for that profile's workflows, then deleting the profile log)
Process
Step 1: Find the Adoption Log
Read .dex/adoptions/$ARGUMENTS.json. If it is not there and $ARGUMENTS looks like a handle, check System/.dex/adoptions/profiles/$ARGUMENTS.json instead.
If the file doesn't exist:
No adoption record found for "$ARGUMENTS".
This means either:
- It was never adopted via /diff-adopt
- It was already removed
- The adoption log was deleted
I can't safely remove it without knowing what was created.
If you want to manually clean up, check .claude/skills/ for related skill folders.
Stop here. Do not attempt to guess what to delete.
Step 2: Parse the Log
Extract:
files_created— every file created during adoptionfolders_created— every folder createdclaude_md_sections— every CLAUDE.md section title added
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.
