bulwark AGENTS.md

Repository guidance for AI coding agents working on Bulwark, a Rust tool that checks Linux computers for security problems and signs of intrusion using YAML rules.

In plain words
What is it for?
Building, testing, formatting, and running Bulwark's core, command-line tool, and graphical app.
Why use it?
It gives agents the project background, required development commands, and architectural guidance before they change code.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 B, and why

bulwark AGENTS.md scanned grade B 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 2d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

Two different mechanisms, deliberately: the GUI uses `pkexec` with `polkit/com.bulwark.policy` (`auth_admin`, one prompt per privileged scan — `auth_admin_keep` was dropped because it caches authorization for the *generi

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What this is

Bulwark scans a Linux host for security misconfigurations and intrusion indicators using a native Rust rule engine over declarative YAML rules, and explains findings in plain language with a suggested fix. Design rationale, architecture, and alternatives-considered all live in docs/guide/architecture.md — read that before making an architectural change, not just this file. Background research grounding the rule checklist (Lynis, MITRE ATT&CK, HackTricks) is in research/2026-07-11-linux-security-checklist/report.md.

Build & development commands

# Core + CLI
cargo build --workspace
cargo test --workspace
cargo clippy --workspace --all-targets -- -D warnings
cargo fmt --all                        # cargo fmt --all -- --check in CI
cargo run -p bulwarkctl -- scan
cargo run -p bulwarkctl -- rules validate rules/
cargo test -p bulwarkctl --test e2e -- --ignored --test-threads=1   # needs Docker; see below

# GUI (from apps/bulwark-app/)
npm install
cargo tauri dev                        # hot reload for frontend; Rust/tauri.conf.json changes need a restart
cargo tauri build                      # produces .deb, .rpm, .AppImage in target/release/bundle/
npx tsc --noEmit                       # type-check the frontend
npm run lint                           # eslint
npm run format:check                   # prettier --check

# Docs site (from docs/)
npm install
npm run dev                            # local preview
npm run build                          # static build to docs/.vitepress/dist

# Packaging (from workspace root, after a release build)
cargo build --release -p bulwarkctl
cargo deb -p bulwarkctl --no-build       # requires `cargo install cargo-deb`
cargo generate-rpm -p crates/bulwarkctl  # requires `cargo install cargo-generate-rpm`

CI (.github/workflows/ci.yml) runs fmt-check, clippy -D warnings, cargo test --workspace, rules validate rules/, and a frontend typecheck — run all of these locally before considering a change done.

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.

bulwark AGENTS.md is an instructions file published in the GitHub repository vietanhdev/bulwark (11 stars, last pushed 9d ago), licensed Apache-2.0. It adds 13,637 tokens to every session, about $0.0682 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
