Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00032 | $0.00403 |
| Opus 5 | $0.00016 | $0.00201 |
| Sonnet 5 | $0.00006 | $0.00081 |
| Haiku 4.5 | $0.00003 | $0.00040 |
Grade A, and why
presence-status 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 10d 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
Parse $ARGUMENTS:
-
If
--zerotrustis present: produce a focused checklist showing the status of each Zero-Trust control. Use:PRESENCE_ROOT="${CLAUDE_PLUGIN_ROOT:-$(realpath ~/.claude/plugins/presence 2>/dev/null || echo .)}" PYTHONPATH="$PRESENCE_ROOT/lib" python3 -c " from doctor import zerotrust_report for line in zerotrust_report(): print(line) "Show the output verbatim. Then briefly summarize: how many controls are OK vs FAIL, and whether the active preset is
zerotrust(if not, mention that ZT controls are inactive even if available). -
Otherwise (no flag): produce a single concise paragraph summarizing active preset, current repo id (12-char hash), model size (in KB if > 1KB), pending event count, and whether there are any new errors/warnings since last session. Do not show the full doctor report; that's what
/presence-doctoris for.PRESENCE_ROOT="${CLAUDE_PLUGIN_ROOT:-$(realpath ~/.claude/plugins/presence 2>/dev/null || echo .)}" PYTHONPATH="$PRESENCE_ROOT/lib" python3 "$PRESENCE_ROOT/lib/doctor.py" --cwd "$PWD" --jsonFormat response as one or two sentences. Example: "presence is on preset
solo-devfor repoa1b2c3d4e5f6: 2.3 KB of model notes, 4 pending events, no warnings."
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.

presence-status is a command published in the GitHub repository sara-star-quant/presence (7 stars, last pushed 3d ago), licensed Apache-2.0. It adds 32 tokens to every session and 403 once invoked, about $0.0002 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.
