Plugin Claude Code
Evidence-driven development pipeline with multi-model code review.
Command Claude Code
Implement tasks from an OpenSpec change (Experimental).
Command Claude Code
Archive a completed change in the experimental workflow.
Command Claude Code
Enter explore mode - think through ideas, investigate problems, clarify requirements.
Command Claude Code
Propose a new change - create it and generate all artifacts in one step.
Command Claude Code
Sync delta specs from a change to main specs.
Command Claude Code
Update a change - revise existing planning artifacts and keep them coherent (Experimental).
Skill Claude CodeCodex
Implement tasks from an OpenSpec change. Use when the user wants to start implementing, continue implementation, or work through tasks.
Skill Claude CodeCodex
Archive a completed change in the experimental workflow. Use when the user wants to finalize and archive a change after implementation is complete.
Skill Claude CodeCodex
Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
Skill Claude CodeCodex
Propose a new change with all artifacts generated in one step. Use when the user wants to quickly describe what they want to build and get a complete proposal with design, specs, and tasks ready for implementation.
Skill Claude CodeCodex
Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
Skill Claude CodeCodex
Update an OpenSpec change by revising its existing planning artifacts and keeping them coherent with one another. Use when the user wants to revise a change's plan, fold new decisions into it, or reconcile its artifacts after an edit. Never edits code.
Instructions file GitHub Copilot
Instructions for heurema/signum: Review code only after the PR intake gate is satisfied (intake/pass or maintainer override). If intake is not satisfied, focus on the missing intent/risk signal instead of detailed code style.
Instructions file CodexOpenCode
Instructions for heurema/signum, covering agents.md, purpose, agent entry points, repo-specific rules and high-risk paths.
Skill Claude CodeCodex
Use when the user wants contract-first development — define correctness before coding, implement against a contract, audit with multiple models, and package proof artifacts.
Agent
Parses a user feature request into a structured contract.json. Scans codebase for scope signals and risk assessment. Read-only -- never writes code files, only generates contract.json.
Agent
Implements code changes according to a contract.json specification. The ONLY agent in Signum that writes code. Includes a repair loop: generate -> check -> fix -> check (max 3 attempts).
Agent
Synthesizes project.intent.md and project.glossary.json from deterministic scan signals. Uses ranked source hierarchy and explicit-only Non-Goals extraction. Emits per-section evidence comments and confidence annotations. Read-only — never writes files directly (presents draft for user confirmation).
Agent
Semantic code reviewer using Claude Opus. Part of the multi-model audit panel. Analyzes diff against contract for bugs, security issues, and logic errors. Read-only -- never modifies code.
Agent
Combines multi-model review results into a consensus verdict. Reads review outputs from Claude, Codex, and Gemini, plus mechanic report. Applies deterministic synthesis rules to produce final audit decision. Read-only -- never modifies code.
Command
Bootstrap project context (project.intent.md and project.glossary.json) from an existing codebase using deterministic scan + LLM synthesis + interactive editing. Use --harness to scaffold additional repo-level harness docs.
Command
Evidence-driven development pipeline with multi-model code review. Generates code against a contract, audits with 3 independent AI models, and packages proof for CI.
