verification-before-completion

verification-before-completion is a skill for Claude Code from vigneshbarani24/sap-superpowers. It costs 43 tokens per session (2,710 once invoked), scanned A, original, MIT.

A completion checklist that requires evidence before a coding task or generated deliverable is called finished. It checks that outputs, sources, and verification steps are explicitly recorded.

In plain words
What is it for?
Use it to verify files, findings, cited sources, test results, and other required outputs before handoff.
Why use it?
It helps prevent incomplete work from being presented as done and exposes assumptions that were never tested.

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

verification-before-completion 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 7d 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.

The opening of the file, as written. The whole thing — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verification Before Completion

This skill enforces that no task is ever marked "done" without enumerated outputs, cited evidence, and a completed verification checklist. It is the quality gate for the entire SAP Superpowers system.

Iron Laws

  1. NEVER SAY "DONE" WITHOUT LISTING WHAT WAS PRODUCED. Completion is not a feeling. It is an inventory. Name every output: every file generated, every finding documented, every source cited. If you cannot list it, you did not produce it.

  2. NEVER SKIP VERIFICATION STEPS. Every skill has a Verification section with checkboxes. Each box must be checked with evidence, not assumptions. Skipping a verification step because "it's obvious" is the number one cause of defective SAP deliverables.

  3. ALWAYS PROVIDE EVIDENCE, NOT ASSERTIONS. "This should work" is an assertion. "Tested in SE38, output matches expected result per test case TC-004" is evidence. "The config looks correct" is an assertion. "SPRO path X > Y > Z verified, field ABC set to value 123 matching spec section 4.2" is evidence.

  4. NEVER CONFUSE COVERAGE WITH CORRECTNESS. Touching every item on a checklist is coverage. Producing verifiable output for every item is correctness. Coverage without correctness is a false completion.

  5. COMPLETION IS BINARY. A task is either verified-complete or not-complete. There is no "mostly done," "essentially complete," or "done except for." If any verification item fails, the task is not complete. Period.

What "Done" Means by Skill Type

Process Skills (Consulting, Delivery)

A process skill is complete when:

  • A deliverable file has been generated (Markdown document, matrix, plan, runbook)
  • The deliverable follows the skill's template exactly
  • Every section of the template is filled with project-specific content, not placeholders
  • The skill's verification checklist is fully satisfied
  • The next skill in the workflow chain has been identified and communicated

Evidence: The deliverable file path, section-by-section confirmation, verification checklist status.

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.
