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.

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 | $0.00000 | $0.05788 |
| Opus 5.5 | $0.00000 | $0.02315 |
| Sonnet 5.5 | $0.00000 | $0.01158 |
| Haiku 4.5 | $0.00000 | $0.00579 |
Grade A, and why
forge-prompt-coach 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 14d 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 — 233 lines — stays where its author put it; the contents beside it link to each section on GitHub.
forge-prompt-coach — from a vague request to a buildable one
Evidence base. Every rule below is grounded in Forge's own internal UX research (35 sources, run
forge-2026-09-24-config-v250). The ids in square brackets, such as [GOOG] or [G-Q], are short internal
source labels kept for traceability during development — the underlying research file is a dev-only
artifact and is not part of a fresh install, so the labels are not meant to be dereferenced by the shipped
product; treat this SKILL.md as self-contained. Nothing here is new research. Where this skill makes a
Forge design choice that no source states (for example the exact gap ranking in §2), it says so.
Why this exists. The owner builds Forge for beginners who do not think in computer terms. Beginners write short requests: successful prompts are about 21 words, first attempts fewer than 9 [GOOG]. They expect the AI to understand them the way a person would [JOHNNY] and often cannot put into words what they want [NNG-AB]. One good clarifying question gives a large gain (more than 170% better retrieval in [ALI]); asking only where the intent is genuinely uncertain doubles the benefit [ZC]; bad questions make things worse ([ZOU], secondary, abstract not verified). Anthropic lists checking in or asking clarifying questions too often on simple agentic tasks as something to avoid [CONST]. So this skill does two things: it fills most gaps silently with safe, stated assumptions, and when one gap really matters it asks one easy multiple-choice question.
When to use
- A raw owner request is vague: only a vague verb ("maak het beter", "improve", "fix", "regelen"), fewer than 9 words, a single word ("webshop", "bot"), or taste words without an example.
- A bug report without a symptom ("werkt niet", "kapot", "doet raar").
- Before and during
forge-intake: this skill decides which ONE question the intake asks, if any. - When
forge-promptcheck askreports VAGUE, or the owner asks how to ask Forge for something — give themreferences/HOW-TO-ASK.md. - Mid-run when the goal changes ("laat maar", "eigenlijk", "toch liever") — failure mode F12.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

forge-prompt-coach is a skill published in the GitHub repository ForgeyClap/claude-forge (2 stars, last pushed 16d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 5,788 tokens. 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 2026-09-25.
