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 | $0.00492 | $0.00492 |
| Opus 5.5 | $0.00197 | $0.00197 |
| Sonnet 5.5 | $0.00098 | $0.00098 |
| Haiku 4.5 | $0.00049 | $0.00049 |
Grade A, and why
ForgeGuard 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 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.

Working in this repository
- Do not run
forgeguard initagainst the repository root. ForgeGuard installs into its own checkout like any other project, writing.claude/settings.json,.claude/skills/, and.forgeguard/. Usesh tests/sandbox.shto build throwaway repositories under the gitignoredsandbox/instead. AGENTS.mdis a symlink toCLAUDE.md; editCLAUDE.md.
Checks
.github/workflows/ci.yml runs, in order:
cargo fmt --all -- --check
cargo clippy --workspace --all-targets --all-features -- -D warnings
cargo test --locked --workspace
cargo build --locked --workspace --release
sh tests/install_test.sh
sh tests/wizard_test.sh
tests/wizard_test.sh drives the interactive init wizard through a
pseudo-terminal, so it needs a built binary and takes the first of
target/debug or target/release. sh tests/logo.sh --check verifies the
banner grid still matches assets/brand/logo-mark.svg; it is not part of CI
because it needs macOS qlmanage and Pillow.
Things that have bitten before
- The Windows release job only builds, so test code that fails to compile there
is never caught by CI. Gate unix-only tests with
#[cfg(unix)]. - A
// forgeguard: allow FG-XXX -- reasonmarker suppresses the rule for only the two lines that follow it, so keep the marker on the line above the finding. - The code graph under
.forgeguard/cache/memory/is a cache: bumpmemory::store::SCHEMA_VERSIONwhen extraction or the schema changes and it rebuilds itself. The committed artifact is.forgeguard/memory/graph.db.zstinstead, which.forgeguard/.gitignoredeliberately does not ignore. - Terminal output uses the stdlib-only
thememodule incrates/forgeguard-cli/src/main.rs— no color crates. Anything it prints must collapse to plain text when stdout is not a terminal orNO_COLORis set.
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.

ForgeGuard CLAUDE.md is an instructions file published in the GitHub repository suiflex/ForgeGuard (14 stars, last pushed 4d ago), licensed MIT. It adds 492 tokens to every session, about $0.0020 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 2026-08-30.
