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 | $0.00178 | $0.03140 |
| Opus 5 | $0.00089 | $0.01570 |
| Sonnet 5 | $0.00036 | $0.00628 |
| Haiku 4.5 | $0.00018 | $0.00314 |
Grade A, and why
psd-atrium 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 5d 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 — 268 lines — stays where its author put it; the contents beside it link to each section on GitHub.
psd-atrium
Atrium is AI Studio's collaborative content workspace at aistudio.psd401.ai.
Staff author documents (markdown) and interactive artifacts (HTML/CSS/JS or
JSX), organize them into collections, control who can view them, and publish
them to the internal "intranet" reader.
This skill gives you version-based read/write access over Atrium's REST API using an AI Studio API key.
Configuration
| Setting | Source | Default |
|---|---|---|
ATRIUM_API_KEY |
required secret | — |
ATRIUM_HOST |
optional secret | aistudio.psd401.ai |
Getting a key: AI Studio → Settings → API Keys → create a key. The raw key is shown once. It needs these scopes:
content:read·content:create·content:update·content:publish_internal
content:publish_public is deliberately withheld from staff/admin defaults — a
public publish returns a queued-for-approval result instead (see below).
Store it per SECRETS-SETUP.md (export ATRIUM_API_KEY=…
in your shell profile, or the Geoffrey .env).
Verify setup before anything else:
bun scripts/run.js status
Command reference
All commands: bun scripts/run.js <subcommand> [flags] from this skill directory.
Setup & discovery
| Command | Purpose |
|---|---|

List collections; only selectableForCreate: true may be used as --collection |
Use collections --shape tree when hierarchy or parentage matters.
Collection management
# District/admin hierarchy
bun scripts/run.js create-collection --name "Business Office" --scope district \
--parent <parent-collection-uuid> --position 10 --visibility internal
# Owner-bound private hierarchy (available to Atrium authors)
bun scripts/run.js create-collection --name "My Research" --scope private
bun scripts/run.js update-collection --id <collection-uuid> \
--parent <new-parent-uuid> --position 20
# Pin a document as a section's landing page
bun scripts/run.js update-collection --id <collection-uuid> \
--landing-object <object-uuid>
# Move a document/artifact; use `none` to remove it from all collections
bun scripts/run.js move-content --id <object-id-or-slug> \
--collection <collection-slug-or-uuid>
What ships with it
4 files 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.

psd-atrium is a skill published in the GitHub repository psd401/psd-claude-plugins (2 stars, last pushed 4d ago), licensed MIT. It adds 178 tokens to every session and 3,140 once invoked, about $0.0009 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 2026-08-31.
