AGENTS.md

techtank-site AGENTS.md is an instructions file for Codex, OpenCode from techtankto/techtank-site. It costs 2,837 tokens per session, scanned A, original, MIT.

Repository-specific instructions for techtankto/techtank-site, a Next.js website for Toronto's volunteer-run technology community. They explain the code layout, site structure, history, and working conventions for coding agents.

In plain words
What is it for?
Use them when working on the site's pages, components, content structure, testing, performance, accessibility, search visibility, or other repository tasks.
Why use it?
They give an agent the project context needed to make changes that fit the existing website and repository practices.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is techtankto/techtank-site's own configuration. It tells Codex and OpenCode how to work on techtank-site 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 techtank-site 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

techtank-site 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 27d 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 — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Guidance for any coding agent working in this repository, and the primary, tool-agnostic context source for all of them (Claude Code, Cursor, Copilot, Codex). Tool-specific files like CLAUDE.md defer to it.

What this repo is

A Next.js (App Router) implementation of techtankto.com, Toronto's volunteer-run tech community website. It funnels visitors into roles: attendee, speaker, host, sponsor, or volunteer.

The PRD (docs/prd/) is a historic record of how the current structure came to be. Read it for context on prior decisions (why a route was shaped that way, what a design token replaced), not as a spec to keep in sync.

House standards live in the vendored skills and load via skill discovery; see §House standards. Application code lives in app/, with shared pieces in components/, constants/, and public/. The initial UI scaffold was generated from the prior PRD via v0.

For developer-facing setup (scripts, directory tree, route map), see README.md.

docs/prd/06-plan.md records the milestone list as it stood during the redesign. docs/prd/03-solution.md records the original route map and per-surface content requirements; README.md is the current route reference.

How the information architecture works

A conversion-oriented onboarding hub, not a flat "link-tree" layout. README.md carries the current route map; docs/prd/03-solution.md carries the shared layouts and navigation as originally specified:

  • /: social-proof-driven home (testimonials, event photos, logo cloud).
  • /about (+ /about/faq, /about/team): values manifesto built on four pillars, Community, Innovation, Teamwork, Respect; FAQ; team roster.
  • /get-involved: onboarding hub with four role sub-pages (Speaker, Host, Sponsor, Organizer Team), each ending in an intake action (email us at [email protected]).
  • /events: embedded Luma calendar.
  • /donate: Stripe and Interac e-transfer donation info. It stays a top-level route rather than nesting under /get-involved, since it is not a role intake form, but the /get-involved sub-nav and the footer link it as part of that grouping.
  • /resources/media-kit: standalone brand assets and fast facts for media.
  • /resources/design-system: brand guidelines and design-token reference.
  • /legal: grouped compliance documents.

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.
