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	$0.00849	$0.00849
Opus 5.5	$0.00340	$0.00340
Sonnet 5.5	$0.00170	$0.00170
Haiku 4.5	$0.00085	$0.00085

Security

Grade A, and why

vytalLink 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 2mo 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.

Repository Guidelines

Project Structure & Module Organization

mobile/: Flutter app + MCP server; code in lib/, design system in design_system/, env samples in environments/.
landing/: Firebase site with HTML/JS under public/ and CSS partials in public/styles/.
mcp-server/: Node MCP server exported as @xmartlabs/vytallink-mcp-server; main file vytalLink_mcp_server.js.
examples/: TypeScript and Python CLI agent examples that consume the MCP server (athletic-analyst-ts/, athletic-analyst-py/).
docs/: Shared guides (e.g., CODE_STANDARDS.md) plus repo-wide references.

Build, Test, and Development Commands

cd mobile && fvm flutter pub get installs dependencies pinned by .fvmrc.
cd mobile && fvm flutter run launches the app on the active device.
cd mobile && ./scripts/checks.sh formats + analyzer + metrics; run before every PR.
cd mobile && ./scripts/integration_test.sh executes the MCP integration flow end-to-end.
cd mobile && ./scripts/clean_up.sh cleans, refetches deps, regenerates build_runner + l10n outputs after model or copy changes.
cd landing && firebase serve --only hosting --port 5000 previews updates; ./scripts/build-css.sh bundles CSS when needed.
cd mcp-server && npm install && npm start starts the standalone server or npm run install-global to expose the CLI.
cd examples && ./scripts/repo.sh help lists setup/build/integration commands for both examples.
cd examples/athletic-analyst-ts && npm install && npm run build prepares the TypeScript example.
cd examples/athletic-analyst-py && python3 -m venv .venv && .venv/bin/pip install -r requirements.txt prepares the Python example.

Coding Style & Naming Conventions

Follow docs/CODE_STANDARDS.md: two-space indent, fvm dart format, clean fvm flutter analyze.
Use English identifiers (lowerCamelCase members, UpperCamelCase types) and package: imports under lib/.
Localize UI strings via lib/l10n/intl_en.arb, regenerate with flutter gen-l10n, avoid hardcoded copy.
Use the shared Logger, prefer const/final, and rely on design system colors.

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.
