eb-v3-spike

A test add-on for checking whether an engineering-board workflow can run a separate analysis task, collect its JSON result, and save it to disk.

In plain words
What is it for?
It is for testing stop-hook dispatch, result capture, and artifact writing in a scratch environment.
Why use it?
It helps evaluate a proposed workflow without installing production hooks or changing the main engineering-board system.

Grade A, and why

eb-v3-spike 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 yesterday.

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

{
  "name": "eb-v3-spike",
  "version": "0.0.1",
  "description": "Composability spike for engineering-board v0.3.0. Tests whether a Stop hook of type:prompt can dispatch Task(subagent_type=finding-extractor) from the main session, capture JSON output, and write it to disk before Stop returns. Installs no production hooks against the engineering-board domain; artifacts land in .eb-v3-spike-artifacts/ in cwd."

Files

What ships with it

1 file beside plugin.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

eb-v3-spike is a plugin published in the GitHub repository GhostlyGawd/engineering-board (0 stars, last pushed yesterday), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. 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.
