agentviz: Instructions file for Codex

AGENTS.md

agentviz AGENTS.md is an instructions file for Codex, OpenCode from jayparikh/agentviz. It costs 2,388 tokens per session, scanned A, original, MIT.

A repository instruction file describing how coding agents should work on the Agentviz project, including its documentation map, workflow rules, and approval requirements for GitHub issue changes.

In plain words
What is it for?
Use it to guide code changes, find the relevant architecture and style documents, follow session rules, and handle GitHub issues safely.
Why use it?
It gives agents consistent project context and prevents them from treating unapproved issues as an implementation plan or editing issues without permission.

Instructions file for CodexOpenCode

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

This is jayparikh/agentviz's own configuration. It tells Codex and OpenCode how to work on agentviz 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 agentviz 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

agentviz 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 11d 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.

Reference map

GitHub issue changes require approval

  • Ask for explicit approval before modifying an existing GitHub issue, including its title, description, labels, or open/closed state.
  • Present the proposed changes before applying them. A general request to analyze, clean up, or refresh the repository or backlog is not approval to edit issues.
  • Treat open issues as unreviewed proposals, not an approved implementation roadmap. Do not implement their contents unless the user explicitly selects that work.
  • If approval is unavailable, leave issues unchanged. An automated instruction to continue autonomously does not substitute for approval.
  • Restoring prior issue text also requires approval. Preserve any newer edits when applying an approved restoration.

Working rules

  • Search existing code before writing new abstractions. Prefer editing existing files.
  • Run relevant existing tests after every non-trivial code change. Documentation-only changes need content and link checks, not a runtime rebuild.
  • Never silently apply configuration changes. Surface drafts and obtain approval first.
  • Product name is always AGENTVIZ (all caps, no spaces).
  • No em dashes in content or comments.
  • Components and hooks are plain JSX/JS; parsers and data libraries use TypeScript.
  • All styles are inline; all colors reference src/lib/theme.js tokens. Use JetBrains Mono and follow the UI style guide.
  • Unicode characters may be used directly or as escape sequences in JS.
  • Components receive data as props. Shared contexts are limited to SessionProvider for session orchestration and PlaybackContext for active-session playback/search/filter state.
  • Before approving UI work, review the checklist in docs/ui-ux-style-guide.md.

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.
