OPSX: Verify

A verification command for checking whether implemented code matches its change documents, such as specifications, tasks, and design notes.

In plain words
What is it for?
Use it to select a specific OpenSpec change, inspect its status and workflow, load its documents, and verify the implementation.
Why use it?
It exposes differences between what was planned and what was built before the change is archived.

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

OPSX: Verify 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verify that an implementation matches the change artifacts (specs, tasks, design).

Input: Optionally specify a change name after /opsx:verify (e.g., /opsx:verify add-auth). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.

Steps

  1. If no change name provided, prompt for selection

    Run openspec list --json to get available changes. Use the AskUserQuestion tool to let the user select.

    Show changes that have implementation tasks (tasks artifact exists). Include the schema used for each change if available. Mark changes with incomplete tasks as "(In Progress)".

    IMPORTANT: Do NOT guess or auto-select a change. Always let the user choose.

  2. Check status to understand the schema

    openspec status --change "<name>" --json
    

    Parse the JSON to understand:

    • schemaName: The workflow being used (e.g., "spec-driven")
    • Which artifacts exist for this change
  3. Get the change directory and load artifacts

    openspec instructions apply --change "<name>" --json
    

    This returns the change directory and context files. Read all available artifacts from contextFiles.

  4. Initialize verification report structure

    Create a report structure with three dimensions:

    • Completeness: Track tasks and spec coverage
    • Correctness: Track requirement implementation and scenario coverage
    • Coherence: Track design adherence and pattern consistency

    Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.

  5. Verify Completeness

    Task Completion:

    • If tasks.md exists in contextFiles, read it
    • Parse checkboxes: - [ ] (incomplete) vs - [x] (complete)
    • Count complete vs total tasks
    • If incomplete tasks exist:
      • Add CRITICAL issue for each incomplete task
      • Recommendation: "Complete task: " or "Mark as done if already implemented"

    Spec Coverage:

    • If delta specs exist in openspec/changes/<name>/specs/:
      • Extract all requirements (marked with "### Requirement:")
      • For each requirement:
        • Search codebase for keywords related to the requirement
        • Assess if implementation likely exists
      • If requirements appear unimplemented:
        • Add CRITICAL issue: "Requirement not found: "
        • Recommendation: "Implement requirement X: "
  6. Verify Correctness

    Requirement Implementation Mapping:

    • For each requirement from delta specs:
      • Search codebase for implementation evidence
      • If found, note file paths and line ranges
      • Assess if implementation matches requirement intent
      • If divergence detected:
        • Add WARNING: "Implementation may diverge from spec: "
        • Recommendation: "Review : against requirement X"

    Scenario Coverage:

    • For each scenario in delta specs (marked with "#### Scenario:"):
      • Check if conditions are handled in code
      • Check if tests exist covering the scenario
      • If scenario appears uncovered:
        • Add WARNING: "Scenario not covered: "
        • Recommendation: "Add test or implementation for scenario: "
  7. Verify Coherence

    Design Adherence:

    • If design.md exists in contextFiles:
      • Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
      • Verify implementation follows those decisions
      • If contradiction detected:
        • Add WARNING: "Design decision not followed: "
        • Recommendation: "Update implementation or revise design.md to match reality"
    • If no design.md: Skip design adherence check, note "No design.md to verify against"

    Code Pattern Consistency:

    • Review new code for consistency with project patterns
    • Check file naming, directory structure, coding style
    • If significant deviations found:
      • Add SUGGESTION: "Code pattern deviation: "
      • Recommendation: "Consider following project pattern: "

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.

OPSX: Verify is a command published in the GitHub repository rivet-dev/actors (6,096 stars, last pushed 3d ago), licensed Apache-2.0. It adds 13 tokens to every session and 1,416 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
