data-control-center: Instructions file for Codex

AGENTS.md

data-control-center AGENTS.md is an instructions file for Codex, OpenCode from hypertrial/data-control-center. It costs 406 tokens per session, scanned A, original, MIT.

Repository instructions for Data Control Center, a local-only app for uploading, profiling, exploring, and querying datasets. The frontend and backend technologies, setup commands, and security boundaries are specified.

In plain words
What is it for?
Use them when developing or validating the app, changing its frontend or backend, handling local uploads, or updating dependencies and project commands.
Why use it?
They help keep user data on the workstation and prevent changes that would accidentally introduce hosting, shared access, accounts, or other unsupported assumptions.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is hypertrial/data-control-center's own configuration. It tells Codex and OpenCode how to work on data-control-center 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 data-control-center 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

data-control-center 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 1mo 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

Agent entry point

This repository uses the Universal Pad specification for non-trivial agentic work.

Git is the source of truth for code. CI is the source of truth for verification. Pad is the source of truth for intent, scope, status, dependencies, decisions, evidence, and handoffs.

Read PROJECT_AGENT.md before implementation. It holds repository-specific invariants, stack notes, and the native verification commands wrapped by scripts/verify-fast and scripts/verify.

Work

Use Pad collections Work and Plans only.

Work types: Feature, Bug, Refactor, Investigation, Maintenance. Plans are multi-ticket containers only.

Statuses (machine values): backlog, ready, in-progress, blocked, review, done.

Risk: r0 (trivial), r1 (normal), r2 (consequential), r3 (critical).

Do not create Ideas, Tasks, chores, or extra default types. Do not run the Pad onboard playbook.

Lifecycle

specify → test/reproduce → implement → targeted verification → full verification → adversarial review → fix findings → re-verify → CI → evidence → done

Do not start material implementation until the ticket is ready: intended behavior, invariants, regression surface, and verification are specified.

Implement the smallest coherent change. Do not silently expand scope. Put unrelated work in a new Pad ticket.

Verification

Development feedback: scripts/verify-fast

Completion gate: scripts/verify

A ticket is not done while required verification is failing or unrun. Record why if a required command cannot run.

Evidence and handoffs

Record decisions with pad item decide. Represent blockers as Pad dependencies, not prose.

Incomplete work must include a handoff a fresh agent can resume without chat history.

R2/R3 work needs independent adversarial review before done.

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.
