verify-changes

verify-changes is a skill for Claude Code from DDS-Solutions/AI-TadPole-OS. It costs 38 tokens per session (1,106 once invoked), scanned A, a copy of verify-changes, MIT.

A verification practice that proves code changes by running the affected feature, reproducing the original problem, or executing relevant tests.

In plain words
What is it for?
It helps verify bug fixes, new features, and refactors with evidence from actual execution.
Why use it?
It prevents assuming that code works simply because it exists or looks correct.

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

verify-changes 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 6d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/change_verifier.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

[!IMPORTANT] AI Context & Knowledge Heritage

  • Subsystem: Agent Skills Registry / verify-changes
  • Architecture: @docs ARCHITECTURE:Documentation
  • Failure Path: Declaring tasks complete without execution evidence, uninspected compiler errors, or broken invariant tests.
  • Observability: Traceability via execution/parity_guard.py ([SKILL])

Verify Changes — Prove Code Works

Core Principle: "Code that exists" $\ne$ "Code that works." Verification by inspection ("it looks fine") or assumption ("types check out") is prohibited. Verification requires empirical execution evidence.
Workflow Bindings: Integrated into /test, /refactor, and /deploy.

🚦 1. The 4-Tier Verification Hierarchy

Never declare a task "done" without executing the applicable tier:

[TIER 1: COMPILATION] ───> [TIER 2: STATIC LINT] ───> [TIER 3: AUTOMATED TEST] ───> [TIER 4: RUNTIME PROOF]
 tsc / cargo check          eslint / clippy             vitest / cargo test          CLI run / HTTP check
  1. Tier 1 (Compilation & Types):
    • TypeScript: npx tsc --noEmit
    • Rust: cargo check --manifest-path server-rs/Cargo.toml
  2. Tier 2 (Static Analysis):
    • TypeScript: npm run lint
    • Rust: cargo clippy --manifest-path server-rs/Cargo.toml -- -D warnings
  3. Tier 3 (Automated Test Witness):
    • Run Vitest or Cargo tests asserting the modified code paths.
  4. Tier 4 (Runtime Execution Evidence):
    • Execute the actual script or call the endpoint to verify runtime behavior.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
