doff

A command that removes the active masque and returns the coding agent to its normal instructions.

In plain words
What is it for?
Use it to clear the active masque, preserve a record of the last one, and clean up related session settings.
Why use it?
It prevents a temporary working perspective from continuing into later tasks.

Token cost

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.

Security

Grade A, and why

doff 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 2d 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

Doff Masque Command

Remove the active masque and return to baseline.

Instructions

Step 1: Read Session File

Read .claude/masque.session.yaml to check current state.

Step 2: Check State and Update

If file doesn't exist or active.name is null:

  • Report: "No masque is currently active."
  • If previous.name is set, show: "Last worn: [previous.name]"
  • Suggest: "Use /don <name> to adopt a masque."
  • Stop here.

If active.name has a value (masque is active):

Write updated session file using the Write tool to .claude/masque.session.yaml:

# Auto-managed by masques plugin
active:
  name: null
  source: null
  donned_at: null
previous:
  name: <previous-active-name>
  source: <previous-active-source>
  doffed_at: <current-UTC-timestamp>

Where:

  • previous.doffed_at is the current UTC timestamp in ISO format
  • previous.name preserves the name of the masque being doffed
  • previous.source preserves the source for potential re-donning

Step 2b: Clear Spinner Verbs (if applicable)

Check if .claude/settings.local.json exists:

  • If the file does not exist, skip this step — there are no spinner verbs to clean up.
  • If the file exists but has no spinnerVerbs field, skip this step.
  • If the file exists and contains a spinnerVerbs field:
    1. Read the existing settings
    2. Remove the spinnerVerbs key
    3. Write the updated JSON (preserving other fields like permissions)
    4. If the file would be empty or contain only {} after removal, delete it

This returns the spinner to Claude Code defaults.

Step 3: Confirm

Report: ✓ Doffed [name]. Back to baseline.

Tool Calls Summary

This command requires:

  1. Read .claude/masque.session.yaml
  2. Write .claude/masque.session.yaml (if masque was active)
  3. Read .claude/settings.local.json (if exists)
  4. Write .claude/settings.local.json (to remove spinnerVerbs)

Or fewer calls if no masque is active or no settings file exists.

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.

doff is a command published in the GitHub repository ChrisDBaldwin/Masques (14 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 13 tokens to every session and 551 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.
