tell-proof: Instructions file for Codex

AGENTS.md

tell-proof AGENTS.md is an instructions file for Codex, OpenCode from ashishpatill/tell-proof. It costs 2,656 tokens per session, scanned A, original, MIT.

A set of AGENTS.md instructions for Tell, an AI tool that evaluates rendered user interfaces and suggests design improvements. It defines the project mission, rules, file locations, and parallel workstreams.

In plain words
What is it for?
Use it when working on Tell's capture, UI analysis, design direction, reconciliation, or Cursor integration code.
Why use it?
It gives coding agents the project context and boundaries they need to make consistent changes without bypassing human approval or breaking shared data contracts.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions subagents; mentions AGENTS.md; mentions Cursor.

This is ashishpatill/tell-proof's own configuration. It tells Codex and OpenCode 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-proof AGENTS.md 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.

How it starts

The opening of the file, as written. The whole thing — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Cursor Agent instructions

You are building Tell: an AI taste critic for rendered UI. Read USER_STORY.md first — every feature serves Ashish's journey (solo founder, shipped with Cursor, UI looks generic, demo tomorrow).

Mission

Capture rendered UI → deterministic fingerprint → detect tells + drift → taste verdict → voice art-direction → redesign diff → apply in Cursor (human approves).

Non-negotiables

  1. Deterministic corepackages/core has zero LLM calls. Taste/redesign only.
  2. Never auto-apply — MCP tell_apply returns patches; human applies.
  3. Schemas — all boundaries use @tell/schema zod types.
  4. Tokens only in apps/web — no raw hex in classNames (dogfood).
  5. User-first copy — critic voice, problem-oriented, see USER_STORY copy bank.
  6. Measured reconciliation — any after-state must preserve readable contrast and explain the measured improvement.
  7. Build order — follow BUILD.md §8 milestones M1→M10; protect cut line.

Where things live

Path Purpose
packages/schema Zod contracts — edit first
packages/core Capture, fingerprint, detectors
packages/taste Gemini taste + deterministic/Gemini voice direction parsing
packages/redesign Contrast-grounded reconciliation + diff generation
packages/mcp Cursor MCP server
packages/cli tell CLI — diagnose, voice, mcp install, doctor, install-info
apps/web Ashish-facing UI + /api/diagnose, /api/setup/*, /api/voice, /api/redesign, /api/install-info
apps/web/src/lib/cursor-redesign.ts Cursor-SDK-backed patch drafting with deterministic fallback
apps/web/src/lib/repo-runner.ts GitHub clone → install → reachable dev server (local only)
apps/web/src/lib/discover-routes.ts Multi-page route discovery from snapshot HTML
packages/redesign/src/reconcile.ts Deterministic token reconciliation for live seam

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.
