verifying-outcomes

verifying-outcomes is a skill for Claude Code from arozumenko/sdlc-skills. It costs 65 tokens per session (713 once invoked), scanned A, original, MIT.

A checklist and evidence-based process for checking whether a requested software outcome was actually achieved. It verifies behavior, files, connections between components, and related tests.

In plain words
What is it for?
Verify features before declaring them complete, check an issue or pull request before closing or merging it, and produce a report showing what works and what is missing.
Why use it?
It prevents treating completed task steps as proof that the result works. This helps uncover missing files, disconnected configuration, and tests that never run.

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

verifying-outcomes 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verifying Outcomes

"Tasks completed" ≠ "goal achieved." Your job is to verify the outcome, ruthlessly and from evidence.

If the goal is fuzzy, ask for clarification before starting. Don't verify a moving target.

Five Checks

1. STATE the goal

Restate it as a concrete, testable outcome — not as a list of tasks. Write it at the top of the report verbatim.

2. What must be TRUE

List the logical conditions that must hold for the goal to be met. These are assertions about behavior, not about work performed.

  • ✅ "API returns 200 for valid requests and 401 for missing tokens"
  • ❌ "Endpoint was implemented"

3. What must EXIST

List concrete artifacts: files, endpoints, configs, migrations, tests, docs. For each, use Read / Glob / Grep to confirm it exists and contains the expected content. Existence alone isn't enough — empty stubs fail.

4. What must be CONNECTED

Things that exist but aren't wired up are useless. Verify:

  • Imports / exports
  • Route registrations, DI bindings, plugin lists
  • Config keys actually read by the code
  • Tests actually run by the test command (not orphaned files)
  • Migrations actually included in the migration manifest

Use Grep to trace from the artifact to its consumer. If you can't find the consumer, it isn't connected.

5. Where will this BREAK

  • Edge cases and error paths
  • Missing input validation
  • Hardcoded values that should be config / env vars
  • Missing or unhandled env vars (Grep for os.getenv / process.env without defaults)
  • Race conditions, timeouts, retries
  • Test coverage gaps for the new behavior

Output

## Verification: <goal verbatim>

### Verdict: PASS | PARTIAL | FAIL

### TRUE
- <verified condition> — <how you verified>
- ...

### EXISTS
- <artifact> — <path:line> — <what you confirmed>
- ...

### CONNECTED
- <integration point> — <evidence>
- ...

### RISKS
- <where this will break, and why>
- ...

### Summary
<1–2 sentences>

Rules

  • Cite file paths and line numbers for every claim. No hand-waving.
  • A check you can't perform is a FAIL for that check, not a pass-by-default.
  • PARTIAL is for "outcome works on the happy path but a listed risk is real and unaddressed." Don't use it as a polite FAIL.
  • Be honest. The point of this skill is to catch the things the implementer missed — flattery defeats the purpose.

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.

verifying-outcomes is a skill published in the GitHub repository arozumenko/sdlc-skills (20 stars, last pushed yesterday), licensed MIT. It adds 65 tokens to every session and 713 once invoked, about $0.0003 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.
