What is haiku-claude-cli CLAUDE.md?

Project instructions for building and checking a native C++17 Claude command-line program for Haiku OS, with macOS used for development.

Building development or release binaries, running tests, installing or packaging the program, and checking C++ code with cppcheck and flawfinder.

They document the project structure, build targets, tests, installation, packaging, static analysis, and security checks in one place.

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	$0.01860	$0.01860
Opus 5.5	$0.00744	$0.00744
Sonnet 5.5	$0.00372	$0.00372

Security

Grade A, and why

haiku-claude-cli CLAUDE.md scanned grade A with 1 finding 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.

Guidance for Claude Code when working in this repository.

Project

A native Claude CLI for Haiku OS. Single C++17 binary; runtime dependencies are libcurl, OpenSSL, libedit, and nlohmann/json. Targets Haiku x86_64 (primary) and macOS (dev/prototype only).

Source lives in src/. One translation unit per module; each module is a .cpp + .h pair under a lowercase namespace matching the filename (tui::, repl::, tools::, etc.). main.cpp is the entry point and contains the REPL loop, tool dispatch, and Claude API integration.

Build & Test

# ── On Taurus (Haiku — canonical target) ──
make                     # dev build  → build/claude        (-O2)
make release             # opt build  → build-release/claude (-O3 -flto -s)
make test                # run tests
make install             # install to /boot/system/non-packaged
make package             # build HPKG (requires Haiku `package` tool)

# Static analysis and security audit
make lint                # cppcheck  — warning/performance/portability
make security            # flawfinder — CWE security audit (level 3+)
make security-full       # flawfinder — full scan (level 2+)
make check               # lint + security in sequence (CI / pre-release)

# ── macOS / nix (prototype only) ──
nix develop              # enter dev shell (curl, openssl, libedit, nlohmann_json)
nix develop -c make      # build
nix develop -c make test # test

Build artifacts go to build/ (dev) or build-release/ (release). The Makefile uses pkg-config for all dependency flags and works with both gcc (Haiku) and clang (macOS/nix) without modification.

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.
