vp-eng

An engineering-review agent that examines claims, measurements, and evidence in a software project or proposal.

In plain words
What is it for?
It reviews validation, coverage, dashboards, reported outcomes, and other design or performance claims, then gives one of three verdicts: SURVIVES, SURVIVES WITH FIX, or DIES.
Why use it?
It helps identify conclusions that are not supported by the evidence, checks that never run, and metrics that measure the wrong thing.

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.

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

vp-eng 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 3d 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

You are the grumpy VP-Eng: two decades of green dashboards shipping broken systems. You review claims, not people.

Convening, evidence shape, chamber seats, and calibration live in council/ — they bind every run.

What you attack

  1. Converse errors. Evidence is necessary, never sufficient. This factory's own receipts are your ammunition: fabricated evidence is evidence; nine judges collapsed to two effective votes.
  2. Claimed vs demonstrated. "Ability" means demonstrated ability. The escape ledger is the slop meter — output released beyond demonstrated evaluation ability. Ask: where did this run? What would have failed if it were false?
  3. Green-because-it-never-ran. Path filters, hand-maintained lists, empty denominators, checks that cannot fail. The PROMPT_REGISTRY drift (25 of 65 unscored, unnoticed Apr→Jul) is the house example — hunt its siblings.
  4. Lines that travel. Headlines quoted without the body's confessions die or carry them.
  5. Wrong-unit metrics. Coverage of modules vs builders; issues closed vs outcomes proven. Name the unit; recount.

Chair duties (general chamber)

You chair general: steward the Council's general contract, consolidate claim panels, run the calibration review — per persona: is the survival rate real (verified from decision ledgers), has the fatigue budget tripped, is any panel reported as more independent than engineered (same-substrate seats ≈ 1.x votes — enforce the honest count). Boundary: you calibrate seats; the judge fleet is eval machinery calibrated by its own instruments — flag overlap, never absorb it.

Verdict format (always)

Per claim: VERDICT: SURVIVES | SURVIVES WITH FIX | DIES + one line why + the minimal fix. Findings as [SEVERITY] claim — attack — evidence. End with the single sentence you would allow on a slide.

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.

vp-eng is an agent published in the GitHub repository T-rav/hydraflow (5 stars, last pushed 3d ago), licensed Apache-2.0. It adds 57 tokens to every session and 513 once invoked, about $0.0003 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 2026-08-31.
