Tools & capabilities

Argus tools 9

  • argus_auditFast pass — JS, network, accessibility, SEO, security, CSS, content
  • argus_audit_fullDeep pass — adds Lighthouse, responsive checks, memory leak detection, hover-state bugs
  • argus_compareDiff dev vs staging — screenshots, findings delta, environment regressions
  • argus_get_contextCapture everything broken on the open tab — with `resolved / new / persisting` diff vs the last snapshot (the fix loop)
  • argus_watch_snapshotSnapshot the open tab without navigating (preserves auth/form state)
  • argus_last_reportReturn last JSON report without re-running
  • argus_design_auditFigma URL → 13 design-token finding types (color, spacing, typography, shadows, etc.)
  • argus_visual_diffScreenshot baseline comparison. Pass `updateBaseline: true` to reset.
  • argus_pr_validateFetch GitHub PR diff → map changed files to affected routes → targeted audit → baseline-aware block decision (blocks on findings the PR *introduces*) + idempotent PR comment + Check Run → `{ blocked, findings, baseline, reporting }

  • constitution_createDefine project principles, constraints, and preferences that guide all AI-generated artifacts. Use this before specify_start to establish project guardrails.
  • clarify_addFlag ambiguities or questions in specifications that need clarification. Creates a tracked clarification with unique ID.
  • clarify_resolveResolve a pending clarification with an answer. Updates spec.md and logs resolution in research.md.
  • clarify_listList all clarifications with optional status filter (pending/resolved/all). Useful for tracking progress.
  • spec_validateCheck specification quality and completeness. Validates required sections, acceptance criteria, clarifications, and checks for premature implementation details.
  • artifacts_analyzeAnalyze consistency across spec, plan, and tasks artifacts. Verifies that all artifacts are aligned and complete.
  • spec_refineRefine/update an existing specification. Supports updating specific sections (goals, requirements, acceptance, edge-cases) or the full spec. Changes are logged to research.md.
  • prereqs_checkCheck environment prerequisites before project setup. Verifies Node.js version, npm, git, and custom commands are available.
  • specify_startInitialize a new spec-driven project. Creates .dincoder directory with spec.json template. Use this as the first step when starting a new project.
  • specify_describeCreate or update project specification with detailed requirements, goals, and constraints. Use after specify_start to define what the project should do.
  • plan_createGenerate technical implementation plan from the project specification. Creates a step-by-step technical approach with milestones and architecture decisions.
  • tasks_generateGenerate granular, actionable tasks from the technical plan. Creates a task list with specific implementation steps that can be executed sequentially.
