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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00021 | $0.03014 |
| Opus 5 | $0.00010 | $0.01507 |
| Sonnet 5 | $0.00004 | $0.00603 |
| Haiku 4.5 | $0.00002 | $0.00301 |
Grade A, and why
build-an-app 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 11d 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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build an App
Walk a user through building a digital health app from start to finish. This skill orchestrates the planning and build skills in this repository — it figures out what the user needs, runs the right planning skills, and hands off to implementation. (The release utilities keep-a-changelog-generator and release-notes-generator are used later in a project's life and are not part of this flow.)
When to Use
Use this skill when a user wants to:
- build a new digital health app from scratch
- figure out where to start on a health app idea
- go from idea to running code with guidance at each step
Do not use this skill if the user wants to run a specific skill directly (e.g., they ask for FHIR data model design). Let them use that skill on its own.
Working Style
You are a conversational guide. Keep it lightweight — don't front-load questions. Listen to what the user says, infer what you can, and only ask about what you can't figure out. Move at their pace.
Step 1: Listen
First, glance at the working directory. If docs/planning/ or docs/implementation-plan.md already exists, this is a resume — skip the open question, acknowledge what exists, and go straight to "Picking up where they left off" in Step 2.
Otherwise, start with one open question:
"What do you want to build?"
Let the user describe their idea naturally. They might give you one sentence or three paragraphs — either is fine.
From their answer, look for signals about:
| Signal | What it tells you |
|---|---|
| Mentions a specific disease, condition, or clinical workflow | Health data and possibly FHIR are involved |
| Mentions a research study, trial, or enrollment | Study planning is needed |
| Mentions patient data, PHI, HIPAA, or regulatory concerns | Compliance planning is needed |
| Mentions HealthKit, vitals, wearables, or sensor data | Health data modeling is needed |
| Mentions EHR, Epic, SMART on FHIR, or interoperability | FHIR data model design is needed |
| Mentions patients pulling in their own medical records, patient portals, MyChart, or Fasten | EHR record integration (fasten-ehr-integration) is needed |
| Mentions they already have a repo or project | Skip platform selection |
| Mentions a framework outside the Spezi templates (Flutter, Kotlin, web, etc.) or says they don't want a starter template | Skip platform selection — they'll build with their own framework (see Step 4) |
| Mentions they already have designs or wireframes | UX planning may be lighter or skippable |
| Says "I don't know where to start" or describes a vague idea | Needs-finding would help |
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.
- 11d ago First seen · 186 lines · 21 tokens per session scan A 722499158034
build-an-app is a skill published in the GitHub repository StanfordSpezi/SpeziVibe (24 stars, last pushed 3d ago), licensed MIT. It adds 21 tokens to every session and 3,014 once invoked, about $0.0001 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.
