3pv

3pv is a command for coding agents from eddiebelaval/squire. It costs 0 tokens per session (256 once invoked), scanned A, original, MIT.

A session close-out command that checks whether the requested work was built, finished, and actually works.

In plain words
What is it for?
Use it to review the current or a past coding session, run one or all of its three checks, list recent sessions, or produce findings without automatic fixes.
Why use it?
It provides a structured final check instead of relying on an informal feeling that the task is complete. It requires evidence for each conclusion and leaves final approval with a person.

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

3pv 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 5d 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

/3pv - 3-point verification (alias for /plumb)

Run the three-gate close-out on this session: PLUMB (did we build what we set out to build, or veer?), SQUARE (is every corner finished, charter and veers?), LEVEL (does it actually function, per the original ask?).

Load and follow the skill at ~/.claude/skills/plumb/SKILL.md. Execute it end to end.

Arguments

$ARGUMENTS

Quick Reference

  • (none) — verify the current session against turn 1's charter
  • --session <uuid> — verify a past session
  • --list — list recent sessions with timestamps, then stop
  • --cwd <repo> — verify a session from a different project
  • gate1 / gate2 / gate3 — run a single gate only
  • report-only — no auto-remediation; findings and receipts only

The rule that governs this command

No verdict without a receipt. Unproven is UNVERIFIED, never PASS. Never commit or push to close a loop — the human gate stays.

Changes

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.

3pv is a command published in the GitHub repository eddiebelaval/squire (21 stars, last pushed 20d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 256 tokens. 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 2026-08-30.
