A set of rules for storing content and temporary state in a typed frontend, a web interface whose data shapes are checked in code.

Use it when adding site content, deciding where state belongs, handling dates or media entries, or checking that content matches the project's types.

It keeps copy and data in one source of truth and avoids inconsistent state, incorrect dates, missing image details, and misplaced licensed assets.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00049	$0.00319
Opus 5.5	$0.00020	$0.00128
Sonnet 5.5	$0.00010	$0.00064
Haiku 4.5	$0.00005	$0.00032

Security

Grade A, and why

data 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

Data and content

Where content lives, how it's typed, and how state is managed.

All content in constants/. No inline copy or data in components; no external content APIs. Copy is grounded in real facts, never invented.
constants/ is the source of truth. It owns the site's content outright, typed by types/. Where an upstream source seeds it, that source stays a reference for facts not yet captured here; constants/ still wins.
State discipline. Keep state local: useState and URL params for the ephemeral. No speculative global state. Sitewide UI state (a mobile menu, a dialog) goes in one Zustand store; theme is the exception, owned by next-themes and never mirrored in that store.
Dates: zone through fromZonedTime(iso, appTimeZone), never bare new Date(); display-only dates are pre-formatted strings.
Media: every entry carries real dimensions and real alt text; src paths are site-absolute under public/.
Licensed assets stay put. Licensed fonts and imagery ship with the site but are never published to other repos or registries.

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.

data is a skill published in the GitHub repository techtankto/techtank-site (5 stars, last pushed 3d ago), licensed MIT. It adds 49 tokens to every session and 319 once invoked, about $0.0002 per session on Opus 5.5. 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.
