list

A command that shows every available “masque,” a named set of instructions and context for changing how the coding agent approaches work.

In plain words
What is it for?
Use it to view masque names, versions, domains, short descriptions, sources, and which masque is currently active.
Why use it?
It gives you one current catalogue instead of requiring you to inspect configuration files or remember what is installed.

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.

Per session 7 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 792 The whole file, excluding the scripts and references it only reads on demand.

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

list 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.

Masque List Command

Display all available masques that can be donned.

Instructions

  1. List masques via the masques-cli CLI — the one authoritative catalog shared by this plugin and the Masques MCP server (PRD v1.2 M7). Do not read the manifests directly; the CLI merges private over bundled for you.

    Locate the CLI ($MASQUE): use masques-cli if on PATH (installed via uv tool install "${CLAUDE_PLUGIN_ROOT}/services/mcp"), otherwise uv run --project "${CLAUDE_PLUGIN_ROOT}/services/mcp" masques-cli.

    $MASQUE list --json
    
  2. Each entry has name, version, domain, tagline, has_rubric, and source (private or shared). The CLI has already merged the two locations — private wins on a name collision; there is nothing to dedupe.

    (If the CLI is unavailable, fall back to reading the manifests at ${MASQUES_HOME:-~/.masques}/manifest.yaml and ${CLAUDE_PLUGIN_ROOT}/personas/manifest.yaml.)

  3. Check for active masque:

    • Read .claude/masque.session.yaml if it exists
    • Extract active.name from the YAML
    • This determines which masque to mark as "(active)"
    • If the file doesn't exist or active.name is null, no masque is active
  4. Format as a table:

    Available Masques:
    
    Name          Version   Domain                   Source
    ────────────────────────────────────────────────────────────────────
    

★ Mirror 0.1.0 masque-creation shared ← start here Nash 0.1.0 architecture [private] Codesmith 0.1.0 systems-programming shared (active) Chartwright 0.1.0 frontend-analytics shared


- Mark the active masque with `(active)` if one is donned
- Show `[private]` for masques from the private manifest
- Show `shared` for masques from the shared manifest
- Always show Mirror first with ★ marker and "← start here" hint (it's the meta-masque for creating others)

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.

list is a command published in the GitHub repository ChrisDBaldwin/Masques (14 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 7 tokens to every session and 792 once invoked, about $0.0000 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.
