tell-proof: Skill for Cursor

.cursor/skills/tell-github-setup/SKILL.md

tell-github-setup is a skill for Cursor from ashishpatill/tell-proof. It costs 61 tokens per session (332 once invoked), scanned A, original, MIT.

A local workflow that clones a GitHub repository, installs its dependencies, starts its development server, and captures the resulting local website. A repository is a project's source-code folder stored with its history.

In plain words
What is it for?
Use it to implement local repository setup, detect development commands, show progress and errors, and automatically capture a reachable preview.
Why use it?
It removes the manual setup work between receiving a code project and inspecting its running interface.

Skill for Cursor

Written for Cursor: installed under .cursor/.

This is ashishpatill/tell-proof's own configuration. It tells Cursor how to work on tell-proof itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything tell-proof configures →

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

tell-github-setup 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 3d 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.

What it actually says

Tell GitHub setup

Scope

  • apps/web/src/lib/repo-runner.ts
  • apps/web/src/lib/setup-guard.ts
  • apps/web/src/app/api/setup/start|status|stop/route.ts

User journey

Ashish pastes github.com/owner/repo → Tell clones, reads README + package.json, installs deps, starts dev server on a free port, waits for reachable URL, then captures localhost.

Security

  • Local dev only unless explicitly guarded
  • Production/deploy must set TELL_DISABLE_REPO_SETUP=1
  • Executes arbitrary install/dev scripts from cloned repos — never expose publicly

UI requirements

  • Block duplicate clicks while job is active
  • Hide stale capture preview during setup/capture
  • Show job state progression and logs in plain language
  • On failure: show detected commands and offer manual URL paste (needs-manual)

Job states

cloninginstallingdetectingstartingwaitingready | needs-manual | error

DoD

  • Successful clone → install → reachable localhost → auto-capture
  • Failure paths are understandable without reading server logs
  • Setup disabled when guard env var is set
Changes

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.
