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 | $0.00000 | $0.00191 |
| Opus 5 | $0.00000 | $0.00096 |
| Sonnet 5 | $0.00000 | $0.00038 |
| Haiku 4.5 | $0.00000 | $0.00019 |
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 yesterday.
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
GitHub setup rules
/api/setup/*clones repos, runs install scripts, and spawns dev servers — local dev only.- Guard with
setup-guard.tsandTELL_DISABLE_REPO_SETUP=1for production/deploy. - Never expose setup endpoints on public deploy without the guard enabled.
- Job states: cloning → installing → detecting → starting → waiting → ready | needs-manual | error.
- Block duplicate setup clicks; hide stale captures while a job is running.
- Surface plain-language success/failure; never leave Ashish guessing which localhost URL is active.
- On failure, show what was detected from README/package.json and offer manual URL paste.
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 cursor rule published in the GitHub repository ashishpatill/tell-proof (1 stars, last pushed 6d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 191 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 2026-08-31.
