Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00023 | $0.00403 |
| Opus 5 | $0.00012 | $0.00201 |
| Sonnet 5 | $0.00005 | $0.00081 |
| Haiku 4.5 | $0.00002 | $0.00040 |
Grade A, and why
meter-verify 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 8d 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
Your objective is to implement $meter verify <run-id> [--evidence "<description>"] [--update].
Before proceeding, verify that .cocoplus/ exists. If not, output: "CocoPlus not initialized in this directory. Run $pod init to begin." Then stop.
Contract
Read the matching meter record from .cocoplus/meter/, .cocoplus/lifecycle/meter/, or the active session meter file. Compare the recorded output against explicit evidence supplied by the operator or available in lifecycle artifacts.
Report:
- Run ID
- Evidence source
- Outcome level, including whether L4 was reached
- Verification confidence
- Any missing proof needed before the result can be treated as verified
If --update is supplied, append a verification envelope with timestamp, evidence summary, confidence, and outcome level to the run's meter artifact. Do not overwrite raw usage counters or transcript reconciliation data.
Exit Criteria
- Missing run records produce a clear "not found" result.
- Verification distinguishes measured activity from outcome proof.
- L4 is claimed only when the artifact demonstrates durable user-visible outcome.
-
--updatepreserves existing metering fields and appends verification metadata.
Anti-Rationalization
| Shortcut / Temptation | Why It Fails |
|---|---|
| Treat the skill as complete because the file exists | Skill contracts must describe observable behavior and verification, not just command names. |
| Skip artifact and safety checks for a small command | Small commands still mutate state or guide execution; preserve the same gates. |
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.

meter-verify is a skill published in the GitHub repository Snowflake-Labs/cocoplus (720 stars, last pushed 9d ago), licensed MIT. It adds 23 tokens to every session and 403 once invoked, about $0.0001 per session on Opus 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 2026-09-03.
