moradin-measure

moradin-measure is a skill for Claude Code from CloseTheLoops/moradin. It costs 62 tokens per session (1,210 once invoked), scanned A, original, MIT.

A planning step in the Forge process that defines what success means before researching tools or writing code. It records a target metric, a failure threshold, supporting signals, excluded vanity measures, a traffic question, and required measurement setup.

In plain words
What is it for?
Reading the Forge plan and profile, deciding the project stage, and writing the success contract to .forge/measure.md.
Why use it?
It prevents teams from starting implementation without a measurable way to decide whether the result works.

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

moradin-measure 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 5d 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.

The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.

moradin:measure

Before researching tools or writing code: what does working look like, in numbers? Without this, you ship blind and every metric you pick later will be one that flatters you. Takes ~10 minutes.

When invoked

/moradin:measure — requires .forge/plan.md (run /moradin:define first if missing). Read plan.md and profile.md. Draft everything from the plan; the operator corrects. Same rule as define: never a blank page.

Build the Success Contract

Work through in order, one at a time:

  1. Stage label. From the plan's evidence answer: no evidence the problem exists → stage is validation. Evidence but not shipped → launch. Already has users → growth. Say which and why in one sentence.

  2. The one metric that matters. Draft it from the riskiest assumption — the metric should measure exactly the thing v1 must prove. Rules:

    • A rate or ratio, never a cumulative total ("% of signups who do X within 7 days", not "total signups"). Totals only go up; they flatter and inform nothing.
    • A target ("30%") and a kill/pivot threshold with a sample size ("under 10% after 100 signups"). The threshold is what turns the number into a decision instead of a decoration. Say plainly: "if we hit this line, we change course — agreeing on that now is the whole point."
  3. The traffic question. "Where do the first 20 users come from — concretely?" A subreddit they post in, a community they're in, friends in the target group, an audience they have. "Nowhere yet" is a legitimate answer — it means milestone 0 is a validation test (landing page + the concrete channel hunt), because a metric with no visitors is theater.

  4. Supporting signals — max 3. Each with a target and a "measured by." Good candidates: a return-rate (do people come back within a week?), the funnel step before the main metric, and the zero-instrumentation fallback below. Refuse a fourth; tracking everything is how measurement gets abandoned.

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.

moradin-measure is a skill published in the GitHub repository CloseTheLoops/moradin (2 stars, last pushed 27d ago), licensed MIT. It adds 62 tokens to every session and 1,210 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.
