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 | $0.00043 | $0.00353 |
| Opus 5.5 | $0.00017 | $0.00141 |
| Sonnet 5.5 | $0.00009 | $0.00071 |
| Haiku 4.5 | $0.00004 | $0.00035 |
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
Maker/checker verify pass for Agentic Loop Engineering Kit Phase 4.
Runbook: .cursor/skills/agentic-loop/SKILL.md Phase 4.
Hard rules
- Run only after human approves Phase 3 implementation
- Different model/persona than implementer for the same diff
- Present results in Plan mode; do not auto-re-dispatch Failure Router
Verify steps
From profile repo (or --repo):
.cursor/skills/agentic-loop/scripts/gradle-build.sh <repo-path>
.cursor/skills/agentic-loop/scripts/parse-jacoco.sh <repo-path> <jacoco_line_ratio>
- Profile E2E script if defined
- Delta coverage: changed production lines need tests
ce-testing-revieweragainst Phase 1 test matrix
On failure
Classify per GATES.md Failure Router — recommend restart phase, wait for human:
| Signal | Recommend |
|---|---|
| JaCoCo / delta | Phase 4 test-repair → 3 |
| Local build fail | Phase 3 |
| 2+ arch failures | Phase 1 |

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.

loop-verifier is a skill published in the GitHub repository pallerana/agentic-loop-engineering-kit (4 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 43 tokens to every session and 353 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 skills, from other repositories
research-engineer
An uncompromising Academic Research Engineer. Operates with absolute scientific rigor, objective criticism, and zero flair. Focuses on theoretical correctness, formal verification, and optimal implementation across any required technology.
tika-eval-compare
Compare extracts from two Tika builds over a corpus to detect regressions in content, encoding, exceptions, and embedded-document handling. Use for "compare before/after extracts", "eval this change against the corpus".
cua-driver
Use Cua Driver for desktop or browser tasks that are awkward or unavailable through Bash/APIs, or when the user explicitly wants GUI interaction: app testing, visual bug reproduction, form filling, calendar entry, screenshots, and demo recording. Also covers Cua setup; not OpenAI Codex Computer Use or web research.
jetson-validate-image
Use after jetson-flash-image to run static BSP checks, on-target smoke/regression tests on a flashed DUT, or both. Not for build or flash steps. Triggers: validate bsp, on-target validation.
atmos-validation
Validate Atmos projects, components, arbitrary JSON Schema inputs, EditorConfig, and GitHub Actions; use affected-file selection and native CI annotations.
skill-benchmark
Benchmark AI skill effectiveness by measuring implementation quality against legacy constraints.
