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 | $0.01577 | $0.01577 |
| Opus 5.5 | $0.00631 | $0.00631 |
| Sonnet 5.5 | $0.00315 | $0.00315 |
| Haiku 4.5 | $0.00158 | $0.00158 |
Grade A, and why
events-tracker CLAUDE.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 20d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project
Events Tracker — Laravel 12 CMS for tracking events, series, venues, artists, promoters, and related entities for music/arts communities. PHP 8.2+ (sandbox and CI run PHP 8.4), MySQL 8. The frontend is Blade views built with Vite and Tailwind 4, plus jQuery and plain JS. Legacy app skeleton (Kernels/Handler/providers) retained by choice.
Default branch for PRs is main
Common commands
# Static analysis (Larastan, level 5)
composer phpstan
./vendor/bin/phpstan analyse
# Full test pipeline (fresh migrate + seed on the testing DB, then phpunit)
composer tests
# Parallel (what CI runs; each process gets its own <db>_test_N database, so the DB user needs CREATE/DROP on those)
php artisan test --parallel --processes=4
# PHPUnit directly
./vendor/bin/phpunit tests
./vendor/bin/phpunit tests/Feature/EventsControllerTest.php # single file
./vendor/bin/phpunit --filter testEventCreation tests/Feature/... # single test
php artisan test # Laravel wrapper
# Frontend
npm run dev # Vite dev server
npm run build # production build (alias: npm run prod)
npm run lint # eslint resources/assets/js and public/js
npm run format # prettier on resources/**/*.{js,css} (not Blade)
# Laravel
php artisan migrate:fresh
php artisan db:seed --class=ProdBasicDatabaseSeeder # or ProdExtra / ProdPittsburgh
php artisan serve
composer.json scripts call php-latest (a system alias). Plain php artisan ... works fine in dev.
PHPUnit env (phpunit.xml) forces APP_ENV=testing, CACHE_DRIVER=array, SESSION_DRIVER=array, QUEUE_DRIVER=sync, BCRYPT_ROUNDS=4. CI runs the suite in parallel and collects coverage only for pushes to main. Tests run against a real MySQL database (.env.testing, the stage DB) — composer tests clears any cached config and runs migrate:fresh --seed --env=testing first, so a working DB connection is required.
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.

events-tracker CLAUDE.md is an instructions file published in the GitHub repository geoff-maddock/events-tracker (25 stars, last pushed yesterday), licensed MIT. It adds 1,577 tokens to every session, about $0.0063 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 2026-09-01.
