forge

forge is a plugin for Claude Code from alphabravo-oss/guild. Its manifest loads nothing; the 2 commands, 3 agents it bundles cost 249 tokens per session together, scanned A, original, MIT.

A specification tool that researches a codebase and turns the findings and an interview into a detailed, reviewable software specification. It records assumptions, rules, state changes, and agreements before implementation.

In plain words
What is it for?
Use it to investigate a codebase, capture unanswered decisions, compare a proposed change with the current system, review the specification adversarially, and produce an implementation-ready document.
Why use it?
It helps expose missing requirements and hidden constraints early, reducing the risk of building the wrong behavior in an existing or new project.

Security

Grade A, and why

forge 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.

{
  "name": "forge",
  "description": "Codebase-aware specification engine for Claude Code. Runs parallel codebase research, then a grounded interview that captures implicit facts as A-AUTO-NNN entries, emits typed Global Invariants / State Transitions / Contracts tables, runs an adversarial spec review at R3.5, then writes a foundry-ready spec with version frontmatter (v2.1) — locked, classified, citation-backed. Detects brownfield, greenfield, and cosmetic modes; brownfield runs produce a flow delta against the existing system. Forge plans. Foundry builds.",

What it installs

The manifest is a name and a version. 2 commands, 3 agents travel with it, and installing the plugin installs all of them — 249 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
