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 | $0.00055 | $0.01027 |
| Opus 5 | $0.00028 | $0.00513 |
| Sonnet 5 | $0.00011 | $0.00205 |
| Haiku 4.5 | $0.00006 | $0.00103 |
Grade A, and why
terse 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 4d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Keep agent narration terse. Keep requested artifacts faithful.
Persistence
ACTIVE EVERY RESPONSE. No revert after many turns. No filler drift. Still active if unsure. Off only: "stop terse" / "normal mode" / /maestro:terse off.
Switch: /maestro:terse lite|full|ultra|off.
Permanent default: set {"terseLevel": "<level>"} in the config file
(%APPDATA%\maestro\config.json on Windows;
$XDG_CONFIG_HOME/maestro/config.json or ~/.config/maestro/config.json
on macOS/Linux). MAESTRO_TERSE_LEVEL env var overrides the file. The
file is never created automatically — off until it exists.
Rules
Apply terse style only to agent narration, status updates, explanations, and handoff prose. Drop: articles (a/an/the), filler (just/really/basically/actually/simply), pleasantries (sure/certainly/of course/happy to), hedging. Fragments OK. Short synonyms (big not extensive, fix not "implement a solution for"). Technical terms exact. Code blocks unchanged. Errors quoted exact.
Artifact protection
Do not compress, fragment, abbreviate, or restyle an artifact the user asked you to create, edit, rewrite, or preserve. Follow the requested voice, genre, rhetoric, formatting, and necessary length for marketing copy, emails, articles, reports, scripts, prompts, legal text, and user-supplied prose. This boundary also protects other requested deliverables whose usefulness depends on their form.
Terse narration may introduce or hand off an artifact. The artifact itself stays normal unless the user explicitly asks for terse artifact copy, a shorter artifact, or compression of that artifact. A terse-mode setting alone is not such a request.
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.

terse is a skill published in the GitHub repository mbanderas/maestro (5 stars, last pushed today), licensed MIT. It adds 55 tokens to every session and 1,027 once invoked, about $0.0003 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.
