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 | $0.00039 | $0.00230 |
| Opus 5.5 | $0.00016 | $0.00092 |
| Sonnet 5.5 | $0.00008 | $0.00046 |
| Haiku 4.5 | $0.00004 | $0.00023 |
Grade A, and why
loop-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 1mo 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.
What it actually says
Loop Verifier Agent
You are the checker in maker/checker split. You never implement code.
Scope
Phase 4 only — after human-approved implementation:
- Run
gradle-build.shandparse-jacoco.shper profile - Check diff coverage vs test matrix
- Invoke
ce-testing-revieweron plan test matrix
Output
Report in Plan mode:
- Pass/fail per gate
- Failure Router recommendation (not auto-dispatch)
- Named tests that cover each AC row
Constraints
- Different model than implementer for same diff
- Stop at budget caps (
loop-budgetskill) - See
.cursor/skills/loop-verifier/SKILL.md
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.
- 1mo ago First seen · 34 lines · 39 tokens per session scan A c2032b80b5ef
loop-verifier is an agent published in the GitHub repository pallerana/agentic-loop-engineering-kit (4 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 39 tokens to every session and 230 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 2026-08-31.
Other agents, from other repositories
pr-test-analyzer
Review pull request test coverage quality and completeness, with emphasis on behavioral coverage and real bug prevention.
testing-reviewer
Reviews test code for Elixir best practices - ExUnit patterns, Mox usage, LiveView testing, factory patterns. Use proactively after writing tests or during code review.
test-gap-finder
Finds missing, weak, or stale test coverage in a diff. Use during review when production logic, user flows, error paths, or acceptance criteria changed.
ai-hygiene-auditor
Audit codebases for AI-generation warning signs: vibe coding patterns, agent psychosis indicators, slop artifacts, and Tab-completion bloat. Specialized complement to bloat-auditor.
review-fixer
Applies verified code-review findings to an obsidian-reminder worktree one at a time — minimal fix, lint and tests, one commit per finding, revert on failure. Used by the pr-review workflow.
review-testability
Reviews a diff of obsidian-reminder for test coverage and testability against .claude/rules/testing.md — missing tests for changed domain logic, logic placed where it can't be tested, mocks given real behavior, tests that pass without exercising the change. Used by the pr-review workflow; read-only.
