A system-design command for turning a medium or complex feature into a written architecture plan, including its interfaces and database structure.

Use it to explore architecture, define API contracts, plan database changes, and save the result as a design document for a feature.

It gives coding work a shared technical direction before implementation begins and highlights unresolved concerns for review.

Per session 20 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 227 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

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	$0.00020	$0.00227
Opus 5.5	$0.00008	$0.00091
Sonnet 5.5	$0.00004	$0.00045
Haiku 4.5	$0.00002	$0.00023

Measured 22d ago against content hash e24e97bc7c37, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

design 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 22d 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

Design

This command is a door into /temper: it starts a run at Design, or takes up the run that is active, and from there everything happens as /temper does it. There is one flow, and it is ${CLAUDE_PLUGIN_ROOT}/commands/temper.md.

Read ${CLAUDE_PLUGIN_ROOT}/commands/temper.md now and follow it exactly, entering at Design as its section "Entering at a stage" says, with $ARGUMENTS as the spec folder's name. That file was not filled in when you read it: wherever it writes the CLAUDE_PLUGIN_ROOT variable, use the folder that holds ${CLAUDE_PLUGIN_ROOT}/scripts/temper (that path with /scripts/temper taken off), and wherever it writes the ARGUMENTS variable, use $ARGUMENTS. Its first instruction (the enforcement line) applies here too.

Changes

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.
