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 C, and why

webspace_app CLAUDE.md scanned grade C with 2 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 430 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

WebSpace: Flutter app managing multiple websites with per-site cookie isolation via flutter_inappwebview. Platforms: iOS, Android, macOS, Linux (WPE WebKit fork).

Style (output, code, commits)

  • No preamble, no closing fluff, no em-dashes, no emoji.
  • Don't use the phrase "load-bearing".
  • Code first; explain only the non-obvious.
  • Default to no code comments. Only add when the why is non-obvious (hidden constraint, workaround for a specific bug, surprising behavior). Never restate what the code does. Never reference the current task or PR.
  • Commit messages: short subject (<70 chars, imperative), 1-2 line body for the why if needed. No marketing prose, no bullet lists of every changed file, no "this commit also...".
  • Don't speculate. Read the code or docs before asserting an API/version/flag.

Git

  • Never push to master. Branch first.
  • git pull --rebase always.
  • Before pushing a branch, check it still exists on remote; if merged+deleted, branch fresh from master.
  • Translations ride their own commit. A change that adds or renames a user-facing string commits the code plus lib/l10n/app_en.arb; the other 66 app_*.arb files go in a second commit on top of it. A 67-file translation diff otherwise buries the change a reviewer actually needs to read. Applies equally to a key rename (the settings-hints subtitle/hint move) and to adding a locale. Ordering matters: the code commit on its own fails l10n_coverage (it enforces key parity across every locale), so put the translation commit immediately after and push them together. CI runs the pushed head, not each commit, so the pair is green even though the first half is not; a bisect that lands between them will fail l10n, which is the accepted cost of the split.
  • Don't commit derivatives. If a file is the output of a script, parser, compiler, dumper, or any build step that reads from elsewhere — it doesn't belong in the repo. Commit the inputs (sources you author, pinned upstream refs) and the runner (build.rs, scripts, Cargo features); regenerate the output at build time into $OUT_DIR/build//target/. Same applies to vendored third-party source: if a script can fetch + assemble it from upstream at a pinned ref, don't check the upstream tree in. Concrete check before staging: "could I delete this file and reproduce it by running one command from a clean clone?" — if yes, it's a derivative; ignore it. See rust/webspace_adblock/build.rs for an example.

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.
