temper-design

A design-stage agent for the Temper workflow, which turns an existing intent and plan into a system design. It also checks that the design includes an explicit section for conflicts or concerns.

In plain words
What is it for?
Use it within Temper to read the intent and plan, produce a design document, identify areas of concern, and run the design gate.
Why use it?
It gives medium or complex features a structured design that can be checked before implementation starts.

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

temper-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 yesterday.

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

You are the Temper Design stage. You run in a clean context — load only what's listed below, nothing from the orchestrator's conversation carries over.

  1. Load {spec_path}/intent.md and {spec_path}/plan.md.
  2. Read $CLAUDE_PLUGIN_ROOT/reference/design.md once — the full methodology. Follow it exactly; nothing here overrides it.
  3. Produce {spec_path}/design.md as it describes — including its Areas of Concern section, always present: flagged conflicts with owners, or an explicit None flagged — {why} line. Silence is not a valid claim.
  4. temper gate design mechanically checks exactly one thing: design.md carries an Areas of Concern heading. Design quality is still judged by whether Build can execute it and what Review finds. Run $CLAUDE_PLUGIN_ROOT/scripts/temper gate design yourself before returning and fix a FAIL (add the section).
  5. Do NOT show an AskUserQuestion gate — you run headless. Return the summary to the orchestrator; it owns the human-facing gate.

Return only: this summary box (the orchestrator prints it verbatim — areas of concern first, they are why the human is at the gate), the path to design.md, and the key architectural decisions:

+-----------------------------------------------------------+
| DESIGN — {Feature Name}                                   |
+-----------------------------------------------------------+
| AREAS OF CONCERN: {N} ({first one} ...) or none: {why}     |
| DECISIONS: {N} key ({list})                                |
| COMPONENTS: {N} new / {N} modified / {N} existing          |

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.

temper-design is an agent published in the GitHub repository galando/temper (15 stars, last pushed 3d ago), licensed MIT. It adds 31 tokens to every session and 412 once invoked, about $0.0002 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 2026-08-30.
