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 | $0.00048 | $0.03847 |
| Opus 5 | $0.00024 | $0.01924 |
| Sonnet 5 | $0.00010 | $0.00769 |
| Haiku 4.5 | $0.00005 | $0.00385 |
Grade A, and why
create-meta-prompts 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 9d 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.
This is a copy
89% identical to create-meta-prompts — 122 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 526 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Each prompt gets its own folder in .prompts/ with its output artifacts, enabling clear provenance and chain detection.
<quick_start>
- Intake: Determine purpose (Do/Plan/Research), gather requirements
- Chain detection: Check for existing research/plan files to reference
- Generate: Create prompt using purpose-specific patterns
- Save: Create folder in
.prompts/{number}-{topic}-{purpose}/ - Present: Show decision tree for running
- Execute: Run prompt(s) with dependency-aware execution engine

<critical_first_action> BEFORE analyzing anything, check if context was provided.
IF no context provided (skill invoked without description): → IMMEDIATELY use AskUserQuestion with:
- header: "Purpose"
- question: "What is the purpose of this prompt?"
- options:
- "Do" - Execute a task, produce an artifact
- "Plan" - Create an approach, roadmap, or strategy
- "Research" - Gather information or understand something
After selection, ask: "Describe what you want to accomplish" (they select "Other" to provide free text).
IF context was provided: → Check if purpose is inferable from keywords:
implement,build,create,fix,add,refactor→ Doplan,roadmap,approach,strategy,decide,phases→ Planresearch,understand,learn,gather,analyze,explore→ Research
→ If unclear, ask the Purpose question above as first contextual question → If clear, proceed to adaptive_analysis with inferred purpose </critical_first_action>
<adaptive_analysis> Extract and infer:
- Purpose: Do, Plan, or Research
- Topic identifier: Kebab-case identifier for file naming (e.g.,
auth,stripe-payments) - Complexity: Simple vs complex (affects prompt depth)
- Prompt structure: Single vs multiple prompts
If topic identifier not obvious, ask:
- header: "Topic"
- question: "What topic/feature is this for? (used for file naming)"
- Let user provide via "Other" option
- Enforce kebab-case (convert spaces/underscores to hyphens) </adaptive_analysis>
<chain_detection>
Scan .prompts/*/ for existing *-research.md and *-plan.md files.
If found:
- List them: "Found existing files: auth-research.md (in 001-auth-research/), stripe-plan.md (in 005-stripe-plan/)"
- Use AskUserQuestion:
- header: "Reference"
- question: "Should this prompt reference any existing research or plans?"
- options: List found files + "None"
- multiSelect: true
Match by topic keyword when possible (e.g., "auth plan" → suggest auth-research.md). </chain_detection>
<contextual_questioning> Generate 2-4 questions using AskUserQuestion based on purpose and gaps.
Load questions from: references/question-bank.md
Route by purpose:
- Do → artifact type, scope, approach
- Plan → plan purpose, format, constraints
- Research → depth, sources, output format </contextual_questioning>
<decision_gate> After receiving answers, present decision gate using AskUserQuestion:
What ships with it
6 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.
- 9d ago First seen · 526 lines · 48 tokens per session scan A 85a619990aa3
create-meta-prompts is a skill published in the GitHub repository marcusgoll/Spec-Flow (92 stars, last pushed 4mo ago), licensed MIT. It adds 48 tokens to every session and 3,847 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 89% identical to create-meta-prompts, differing in 122 lines, and is treated as a copy.
