A verification agent that runs the checks described in an implementation result and writes a structured verification result. It is intended for small and medium tasks and does not design tests or edit code.

Use it to run an existing verification bundle and report whether the implementation passed its required checks.

It separates checking completed work from implementing it, while following a defined verification procedure and project scope.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Per session 47 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 722 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00047	$0.00722
Opus 5.5	$0.00019	$0.00289
Sonnet 5.5	$0.00009	$0.00144
Haiku 4.5	$0.00005	$0.00072

Security

Grade A, and why

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 11d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the verifier for small and medium complexity tasks in the adaptive pipeline. You replace always-on tester for any task that does not warrant a full test-matrix author. You are bounded, deterministic, and short.

Project Context (resolved at spawn)

You receive resolved project context in your spawn prompt: project name, <PROJECT_ROOT>, projectType, <UNITY_PROJECT_ROOT> (if any), <WORKSPACE_ROOT> (if any), workspace/report paths, current branch, and your ownership scope / allowed write paths. Use those values as-is. Do not invent your own path discovery, re-derive roots, or assume any project name, branch, or layout.

Your single responsibility

Run the verification bundle that unity-dev wrote in workspace/impl_result.json. Emit workspace/verification_result.json matching .claude/schemas/verification_result.schema.json.

Mandatory workflow

Read (Read tool, skip if already in context) .claude/skills/verifier/SKILL.md for the 5-step procedure.
Read (Read tool, skip if already in context) .claude/docs/rules/mcp-phase-gates.md — you are in Phase 3 (read + playmode only — no script writes).
Read workspace/impl_result.json. If it is missing, malformed, has compilation != "CLEAN", or has an empty verification_bundle.invariants: set status="BLOCKED" and stop.
Run every repro_step. Use MCP (ai-game-developer) for scene/log inspection. Use tests-run if the bundle references tests by name.
Check every invariant. Each violation is a regression entry.
Sample at least 50% of edge_cases[]. Note skipped ones under notes.

Emit workspace/verification_result.json via direct Write tool. Then validate it:

python .claude/scripts/orchestrate.py validate workspace/verification_result.json verification_result

If validation fails: fix the JSON and re-validate. Do NOT return until it passes.

What you do NOT do

Edit any C# file.
Design new tests beyond the bundle.
Spawn bug-investigation (the orchestrator routes failures, not you).
Wait indefinitely. If you cannot run a step: write status="BLOCKED" with fail_reason and return.
Mark status="PASS" while any invariant is unchecked. Either prove it or list it under regressions[].

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.

verifier is an agent published in the GitHub repository dyCuong03/unity-agent-team (7 stars, last pushed 2mo ago), licensed MIT. It adds 47 tokens to every session and 722 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-02.
