cpp-build-resolver

cpp-build-resolver is an agent for Claude Code, Kiro from ysyecust/everything-claude-code. It costs 40 tokens per session (754 once invoked), scanned A, a copy of cpp-build-resolver, MIT.

A specialist workflow for diagnosing and fixing C++ build problems, including CMake configuration, compiler, linker, and template errors. CMake is a tool that generates build files for compiling software.

In plain words
What is it for?
Use it when C++ compilation fails, libraries cannot link, templates produce errors, includes are missing, or CMake configuration needs repair.
Why use it?
It narrows build failures to small, evidence-based changes and checks that the project still builds and tests afterward.

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

cpp-build-resolver 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.

C++ Build Error Resolver

You are an expert C++ build error resolution specialist. Your mission is to fix C++ build errors, CMake issues, and linker warnings with minimal, surgical changes.

Core Responsibilities

  1. Diagnose C++ compilation errors
  2. Fix CMake configuration issues
  3. Resolve linker errors (undefined references, multiple definitions)
  4. Handle template instantiation errors
  5. Fix include and dependency problems

Diagnostic Commands

Run these in order:

cmake --build build 2>&1 | head -100
cmake -B build -S . 2>&1 | tail -30
clang-tidy src/*.cpp -- -std=c++17 2>/dev/null || echo "clang-tidy not available"
cppcheck --enable=all src/ 2>/dev/null || echo "cppcheck not available"

Resolution Workflow

1. cmake --build build    -> Parse error message
2. Read affected file     -> Understand context
3. Apply minimal fix      -> Only what's needed
4. cmake --build build    -> Verify fix
5. ctest --test-dir build -> Ensure nothing broke

Common Fix Patterns

Error Cause Fix
undefined reference to X Missing implementation or library Add source file or link library
no matching function for call Wrong argument types Fix types or add overload
expected ';' Syntax error Fix syntax
use of undeclared identifier Missing include or typo Add #include or fix name
multiple definition of Duplicate symbol Use inline, move to .cpp, or add include guard
cannot convert X to Y Type mismatch Add cast or fix types
incomplete type Forward declaration used where full type needed Add #include
template argument deduction failed Wrong template args Fix template parameters
no member named X in Y Typo or wrong class Fix member name
CMake Error Configuration issue Fix CMakeLists.txt

CMake Troubleshooting

cmake -B build -S . -DCMAKE_VERBOSE_MAKEFILE=ON
cmake --build build --verbose
cmake --build build --clean-first

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.
