bazel

bazel is a skill for Claude Code, Codex from OutlineDriven/outline-driven-development. It costs 42 tokens per session (1,889 once invoked), scanned A, original, Apache-2.0.

A guide to using Bazel for C and C++ projects. Bazel is a build and test system; this covers its build files, dependency modules, compiler toolchains, remote execution, sandbox failures, and dependency-graph queries.

In plain words
What is it for?
Use it to write BUILD, MODULE.bazel, and related files; configure C/C++ libraries and programs; register toolchains; debug sandbox failures; and inspect dependency graphs.
Why use it?
It helps diagnose build and test configuration problems without guessing how Bazel's rules, dependencies, or sandbox work.

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 A, and why

bazel 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.

Bazel

Bazel for C/C++ projects: BUILD files, Bzlmod dependencies, toolchain registration, remote execution, dependency graph queries, and sandbox debugging. Grounded against Bazel 9.2.0, where Bzlmod is always enabled, all WORKSPACE logic is removed, and every C++ rule loads from @rules_cc.

Contract

Field Bound contract
Trigger The task writes or debugs Bazel BUILD files, cc_library/cc_binary/cc_test rules, Bzlmod dependencies, toolchain registration, remote execution, sandbox failures, or bazel query/cquery/aquery dependency graphs.
Authority Reversible local: writes only BUILD files, MODULE.bazel, .bzl files, and Bazel output directories (bazel-out, bazel-bin); rollback is version control plus bazel clean. No remote mutation.
Side effect Local builds write to the Bazel output base; remote execution and remote cache flags contact a user-supplied endpoint.
Done The requested targets build or test with bazel build/bazel test, or the blocker is reported with the failing command and output.

Inputs

  • Project layout (required): the source tree and where BUILD files should live.
  • Bazel version (required if not inferrable): run bazel version. Bazel 9 removed WORKSPACE and the native C++ rules; instructions below assume Bazel 9.
  • External dependencies (optional): library names; versions come from the Bazel Central Registry.
  • Remote execution endpoint (optional): a user-supplied remote execution or cache service URL.

Procedure

  1. Lay out the workspace. Bazel 9 uses MODULE.bazel as the only dependency file; there is no WORKSPACE. Put a BUILD file in each package directory. Done when: MODULE.bazel exists at the root and each package has a BUILD file.
my-project/
├── MODULE.bazel
├── BUILD
├── src/
│   ├── BUILD
│   └── main.cc
└── lib/
    ├── BUILD
    ├── mylib.cc
    └── mylib.h
  1. Write BUILD rules. Load every C++ rule from @rules_cc; the native cc_library/cc_binary/cc_test rules were removed from Bazel 9. Done when: every target builds with bazel build.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

bazel is a skill published in the GitHub repository OutlineDriven/outline-driven-development (55 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 42 tokens to every session and 1,889 once invoked, about $0.0002 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 2026-09-06.
