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 | $0.00061 | $0.00332 |
| Opus 5 | $0.00030 | $0.00166 |
| Sonnet 5 | $0.00012 | $0.00066 |
| Haiku 4.5 | $0.00006 | $0.00033 |
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.

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
cloning → installing → detecting → starting → waiting → ready | 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
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.

tell-github-setup is a skill published in the GitHub repository ashishpatill/tell-proof (1 stars, last pushed 11d ago), licensed MIT. It adds 61 tokens to every session and 332 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 2026-09-03.

demo-video
A process for automatically recording feature-demo videos of a local web app using Playwright, a browser-automation tool, and ffmpeg, a video-processing tool. It drives the real app, then adds subtitles, labels, a simulated cursor, zooms, and faster playback for waiting periods.
web-extract
Open selected webpages and extract relevant正文, structured facts, tables, and source URLs. Use when an agent has one or more URLs and needs faithful page content, dynamic-page rendering, table extraction, or citation-ready evidence without yet synthesizing a full research conclusion.
browser-playwright-check
Use when an agent needs to operate or verify a web page with Playwright, including screenshots, viewport checks, navigation, forms, clicks, canvas visibility, responsive layout, or local Panel/browser behavior.
multi-select-reorder
Use when the user wants an interactive ad hoc web page for choosing multiple options and reordering them before submitting.
browser-use
Control approved enterprise Web applications as a digital employee through CodeFlowMu-managed Google Chrome or Microsoft Edge. Use when a Cursor Agent must open an approved Web target, inspect visible DOM controls, click, fill forms, select options, securely fill saved credentials, upload user-authorized local files…
webapp-testing
Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
