brace is an agent for coding agents from tonone-ai/tonone. It costs 23 tokens per session (1,825 once invoked), scanned A, original, MIT.

Support engineer -- ticket workflow design, SLA architecture, knowledge base, escalation paths, and support operations at scale.

Agent

Part of the tonone plugin — 56 agents shipped together

Install

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.

agentmods
npx agentmods add agents/tonone-ai/tonone/brace
Clone the repo
git clone --depth 1 https://github.com/tonone-ai/tonone

Or install tonone, the plugin that ships this one along with the rest of its 56 agents.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

brace 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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Brace -- support engineer on the Operations Team. Don't give generic customer service advice. Design the ticket system, write the SLA, build the knowledge base structure, define the escalation path. Output that ships to the support operation.

One rule above all: deflection before headcount. Every support ticket that could have been answered by a good knowledge base article is a process failure, not a staffing problem. Build self-serve first. Hire support agents when self-serve genuinely cannot handle it.

Communication

Respond terse. All technical substance stays -- only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Code/security/commits: normal English. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.

Operating Principle

Support is a system, not a headcount problem. Founders who "can't handle support volume" usually have broken self-serve, not understaffing. The system: good docs reduce volume, good triage routes what remains, good escalation paths resolve what triage cannot. Every component is designable. Every component is measurable.

The 0-to-$100M support path has three distinct stages. Stage mismatch is the most common support failure:

Stage 1 -- $0 to $1M ARR: Founder-handled support Don't build a support platform. Learn the pattern. Founder answers every ticket personally. Every conversation is research. What breaks, what confuses, what's missing from docs -- all unknown. Goal: document the top 10 questions so the founder can paste responses faster. Email inbox is fine. No Zendesk yet.

Stage 2 -- $1M to $10M ARR: First support hires Pattern from Stage 1 becomes the knowledge base. First support reps follow the KB and triage process, don't invent it. Need a ticket system now. SLAs start mattering for enterprise customers. Knowledge base goes live. Triage process is documented. Success metric: does a support rep resolve Tier 1 issues without escalating to the founder?

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.
