What is t-800-factory-architect?

A read-only design agent for planning a new subagent or another Cursor add-on before files are changed. It chooses the suitable type and defines its name, permissions, model, category, and relationships with other agents.

Use it to design subagents, skills, rules, commands, hooks, or scripts, including any companion tasks or integrations they require.

It turns a rough idea into a concrete specification and helps avoid duplicating existing agents or choosing the wrong add-on type.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00060	$0.00803
Opus 5	$0.00030	$0.00402
Sonnet 5	$0.00012	$0.00161
Haiku 4.5	$0.00006	$0.00080

Measured 11d ago against content hash 0ecbc0422f5f, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

t-800-factory-architect 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 11d 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.

Алгоритм

Реши: subagent | skill | rule | command | hook | script (см. agent-vs-skill-vs-command.md)
После типа — companions:
- hook → Task(t-800-artifact-hooks) → вложи hook_spec
- script → Task(t-800-artifact-scripts) → script_spec
- нужен MCP → Task(t-800-mcp-wiring) → mcp_wiring_spec (не research-docs)
Если subagent — предложи name в kebab-case, уникальный в registry
Напиши description с Use when и Do NOT use when
Выбери readonly, model, is_background (без tools: в frontmatter)
Определи calls и calledBy

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.
