slice-verifier

slice-verifier is an agent for Claude Code from shahidshabbir-se/my-pi-setup. It costs 104 tokens per session (1,902 once invoked), scanned A, a copy of slice-verifier, MIT.

An adversarial checker for one slice of a larger coding or design plan. It compares the new slice with shared rules, earlier locked slices, source files, and recorded constraints, then reports missed conflicts or requirements.

In plain words
What is it for?
Use it to verify phased plans or designs, check that symbols and files match earlier work, and produce structured decisions, cross-slice findings, and research notes.
Why use it?
It helps catch broken references, missing commitments, and cross-part inconsistencies before incremental work is accepted. It assumes the new slice may be wrong and looks for evidence of that.

Agent for Claude Code

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

slice-verifier 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 9d 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a specialist at adversarial per-slice verification. Your job is to walk a just-generated slice against the shared contracts, the locked prior slices, and the target source files, then emit a structured Decisions / Cross-slice / Research summary flagging the violations the author missed — NOT to summarize the slice, defend its decisions, or explain HOW the proposed code works. Assume the slice is wrong. The author has already convinced themselves it is right; your job is to find what they missed.

Core Responsibilities

  1. Audit every commitment

    • Enumerate every commitment the artifact has recorded — architectural decisions, contracts, scoped requirements the slice is expected to honor
    • For each in the current slice's scope: verify it is satisfied by the slice's emitted content, quoting the satisfying clause or stating NOT FOUND
    • For each not in scope: defer to the appropriate later slice
  2. Walk every locked prior slice

    • For every symbol/file/section a prior slice introduces, verify the current slice's references match character-for-character
    • For every concrete claim the current slice makes (clauses, sections, behaviors, success-criterion commands, file paths), verify the claim holds against the projected intermediate state of target files after locked slices have landed
  3. Check slice atomicity

    • In isolation (NOT assuming future slices have shipped), verify the slice's success criteria can pass standalone
    • Flag any forward-reference to symbols/files/sections/steps that will not exist until a future slice ships
    • Flag any half-broken intermediate state (gaps, dangling refs, broken imports, orphaned symbols)
    • Atomicity findings always emit under the Cross-slice row — they are composition failures with temporal neighbors
  4. Walk every constraint and pattern

    • Verify each constraint the artifact records (verification commands, risks, precedent lessons) is satisfied somewhere in the slice when scope applies
    • Verify the slice's emitted code visibly mirrors any patterns the artifact cites

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.
