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 | $0.00022 | $0.00525 |
| Opus 5 | $0.00011 | $0.00262 |
| Sonnet 5 | $0.00004 | $0.00105 |
| Haiku 4.5 | $0.00002 | $0.00052 |
Grade A, and why
presence-preset scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Parse the user's argument ($ARGUMENTS) to determine the action:
-
If empty or the word
list: list all available presets, marking the active one. Use:PRESENCE_ROOT="${CLAUDE_PLUGIN_ROOT:-$(realpath ~/.claude/plugins/presence 2>/dev/null || echo .)}" PYTHONPATH="$PRESENCE_ROOT/lib" python3 -c " from presets import list_presets, active_preset_name active = active_preset_name() for name, source in list_presets().items(): mark = '* ' if name == active else ' ' print(f'{mark}{name:24} ({source})') "Then briefly describe each preset by reading the
_descriptionfield from$PRESENCE_ROOT/presets/<name>.json. -
If
use <name>: activate that preset. Use:PRESENCE_ROOT="${CLAUDE_PLUGIN_ROOT:-$(realpath ~/.claude/plugins/presence 2>/dev/null || echo .)}" PYTHONPATH="$PRESENCE_ROOT/lib" python3 -c " import sys from presets import use_preset res = use_preset('<NAME>') if res.ok: print(f'activated preset: <NAME> (from {res.source})') else: print(f'ERROR: {res.error}', file=sys.stderr) sys.exit(1) "Replace
<NAME>with the user's chosen name. If activation fails because the preset doesn't exist, list the available ones (using the script above) and ask the user to pick one via AskUserQuestion. If it fails due to a parse error, surface the parse error verbatim. Do not silently fall back to a different preset. -
If switching to
zerotrust: warn the user that hard commit gates will activate and that v0.2 features (encryption, audit log) are not yet shipped. Confirm via AskUserQuestion before activating.
The available built-in presets are: solo-dev (default), team-oss, enterprise-strict, zerotrust. Custom presets can be added under ~/.claude/presence/presets/<name>.json.
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-preset is a command published in the GitHub repository sara-star-quant/presence (7 stars, last pushed 5d ago), licensed Apache-2.0. It adds 22 tokens to every session and 525 once invoked, about $0.0001 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.
Other commands, from other repositories
fable-eval
Run the fable-mode eval suite (probes → pairwise judge → report). Costs tokens — runs headless claude many times. Optional arg: a probe id substring to filter.
decree
Issue a decree. Seats the organization on first use, then dispatches the teams.
fable-status
Report fable-mode posture — output style, model/effort, hook telemetry drift counts.
report
The full account of the current decree — every figure verified before stated.
roster
Show the organization — roster, defect ledger, replacements, current cycle.
lore
Turn the lore on or off. Same organization, same rules — different register.
