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 | $0.00131 | $0.01350 |
| Opus 5 | $0.00066 | $0.00675 |
| Sonnet 5 | $0.00026 | $0.00270 |
| Haiku 4.5 | $0.00013 | $0.00135 |
Grade A, and why
class-intercom scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Class Intercom CLI
A self-contained CLI for Peninsula School District's Class Intercom (social media / school comms platform), generated with Printing Press from the live web app and hand-extended for PSD. Read-focused (content feed, channels, social feed, moderation, reports, tasks); the only write is create-draft, which can only create an unsent draft.
Built for PSD's Class Intercom workspace. Auth is your own browser session, so it works for whatever the authenticated account can access.
Setup (one-time)
1. Resolve the binary
The binary is not committed to the repo. Resolve it once — this downloads the prebuilt binary for your platform from the repo's GitHub Release (or builds it from cli/ if you have Go and no network):
BIN="$(bash scripts/ensure-binary.sh)" # run from this skill's directory
"$BIN" --version
Use "$BIN" for every command below. It caches under ~/.cache/classintercom-pp-cli/, so this is a one-time cost.
2. Authenticate (Chrome cookie)
Auth is a Class Intercom session cookie read from Chrome. Install the cookie extractor once, then log in:
uv tool install pycookiecheat # one-time; the CLI shells out to it
# Be logged into app.classintercom.com in Chrome, then:
"$BIN" auth login --chrome # approve the macOS Keychain prompt if shown
"$BIN" auth status # should print "Authenticated"
Re-run auth login --chrome if the session expires.
Global flags
Every command supports --json, --csv, --compact, --agent (all agent-friendly defaults), --dry-run, and --select <fields>. Framework commands sync (mirror to local SQLite), search, and api (browse all endpoints) are also available.
Read commands
Channels
"$BIN" channels --json # social channels with their UUIDs (value), network, label
The value field is the channel UUID you pass to create-draft --channel.
Content / activities (content <cmd>)
What ships with it
60 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.
- 2d ago First seen · 111 lines · 131 tokens per session scan A d554aae6a9cd
class-intercom is a skill published in the GitHub repository psd401/psd-claude-plugins (2 stars, last pushed 9d ago), licensed MIT. It adds 131 tokens to every session and 1,350 once invoked, about $0.0007 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.
