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 | $0.00012 | $0.00316 |
| Opus 5.5 | $0.00005 | $0.00126 |
| Sonnet 5.5 | $0.00002 | $0.00063 |
| Haiku 4.5 | $0.00001 | $0.00032 |
Grade A, and why
bart scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
When the hook runs, this text never reaches Claude: the command opens the goal workspace for this chat and ends the turn without a reply. You are reading it because the hook did not run — this session loaded its hook configuration before the plugin was installed or updated, and resuming a session keeps that configuration. So open the workspace yourself, the way the hook would:
"$HOME/.human-compact/bin/hc" chat-ui --session ${CLAUDE_SESSION_ID} --cwd "$(pwd)"
If that path does not exist, use hc chat-ui with the same arguments. The
command's last line is a http://127.0.0.1:PORT URL, which it opens in the
browser; a line above it beginning note: is for the reader too. A workspace
already open on older code than the plugin on disk is replaced rather than
reused, so the URL may differ from the one an earlier tab is on. Reply with
that URL, any note, and one sentence: the workspace is open, and a new Claude
Code session will open it without a reply. Nothing else: no other commands, no
files, no summary of the goals.
From this point the chat's goals document is injected as context on session
start, later messages, subagents and tool batches. /bart disable turns
that off for this chat.
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.

bart is a skill published in the GitHub repository divadbaroon/claude-plugins (4 stars, last pushed 1mo ago), licensed MIT. It adds 12 tokens to every session and 316 once invoked, about $0.0000 per session on Opus 5.5. 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.
