Code Builder

Code Builder is a skill for Claude Code from Razaib-khan/ForgeWeave. It costs 20 tokens per session (577 once invoked), scanned A, original, MIT.

A skill for turning an implementation plan into organized working code. It makes decisions about the framework, folders, and module boundaries, then checks that the result compiles or passes basic checks.

In plain words
What is it for?
Use it to scaffold a module, component, or service, or to implement a planned feature while following existing code and stated coding standards.
Why use it?
It connects high-level requirements to concrete files and code while keeping the structure organized. It is meant for building features, not debugging or simple renames.

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

Code Builder 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/scaffold_module.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Code Builder

Purpose

Take a structured plan and produce working, well-organized code. Makes architecture decisions (framework choice, folder structure, module boundaries), generates the code, and verifies it compiles or passes basic checks.

When to Use

  • A planner skill has produced an execution plan
  • The user asks to "implement" or "build" a feature from requirements
  • Scaffolding a new module, component, or service
  • Translating architecture decisions into concrete code

When Not to Use

  • The code change is a simple rename or refactor — use refactor-engine
  • Only tests are needed — use test-generator
  • The task is debugging an existing issue — use debugger

Inputs

Input Type Required Description
plan object Yes The execution plan from the planner skill
existing_code string No Description of existing codebase structure
standards array No Coding standards to follow (e.g., TypeScript strict, PEP 8)

Expected Outputs

Output Description
New or modified files Working code implementing the plan
Folder structure Organized module layout
Architecture notes Key decisions made during implementation

Exact Workflow Steps

  1. Review the plan and understand the architecture
  2. Create folder structure matching project conventions
  3. Implement each module following existing patterns
  4. Add type annotations and documentation as code is written
  5. Verify the code compiles or passes syntax checks
  6. Run existing tests to confirm no regressions

Required Checks

  • Code compiles without errors
  • Existing tests still pass
  • Code follows project conventions (naming, imports, formatting)
  • New exports are properly typed

Failure Modes

Failure Condition Response
Code doesn't compile Fix type errors and re-verify
Existing tests fail Identify root cause and fix before continuing
Architecture decision contradicts plan Flag to planner for resolution

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.

Changes

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.

Code Builder is a skill published in the GitHub repository Razaib-khan/ForgeWeave (1 stars, last pushed 4mo ago), licensed MIT. It adds 20 tokens to every session and 577 once invoked, about $0.0001 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 2026-08-31.
