hoop: Skill for Claude Code

.claude/skills/evidence/SKILL.md

evidence is a skill for Claude Code from hoophq/hoop. It costs 75 tokens per session (2,722 once invoked), scanned A, original, MIT.

An evidence-collection workflow for a software ticket. It captures before-and-after views of the real user flow and packages them with a short evidence document for review.

In plain words
What is it for?
Use it after quality checks to capture comparison images and write an EVIDENCE.md file before sending a ticket for review.
Why use it?
It gives reviewers visible proof that a change works and did not break existing behaviour. It focuses on user-facing screens, API responses, logs, or command output rather than internal test output alone.

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

evidence scanned grade A with 1 finding 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.

The scan reads SKILL.md. This mod also ships 9 executable files (compare.sh, compose-video.sh, examples/access-control.flow.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 210 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Evidence for a ticket

Evidence is what convinces a person in two minutes that the change works and breaks nothing. A reader must be able to COMPARE: every image puts "before" and "after" side by side, with a label on each panel. Model: "Testing" in PR #1937.

Deliverable, and nothing else, in ~/evidencias/<TICKET-ID>/:

EVIDENCE.md
1-<question>.png      one comparison image per question, 2 to 4 in total
2-<question>.png

When the change has a flow, the comparison is a video of it instead: a UI flow (model: ENG-596), or a terminal flow with each step explained on screen. <flow>.gif for the PR and <flow>.mp4 for Linear, 1 or 2 flows. A PNG stays for a single state: one API response, one log line.

Everything else (raw captures, logs, snapshots, scripts, test output) goes to ~/evidencias/.archive/<TICKET-ID>/. Never inside the ticket folder.

1. Plan the captures (before you run anything)

For each Definition of done item, write one line:

Question a reader asks Surface a person meets Capture
"Does the sidecar get the same rules?" GET /api/sidecars/configuration curl | jq → PNG
"Does the admin screen change?" rule edit page browser screenshot
"Is the page fast, and does it show X?" the page, used end to end recorded flow → side-by-side GIF/MP4
"Does the CLI tell the user why?" hoop exec, then the session API VHS tape → side-by-side GIF/MP4

Surfaces, best first: the UI; an API response; a sidecar, gateway or agent log line; CLI output. Never an internal DB snapshot or go test output: a test is proof for CI, not for a reader.

When the UI changes, the surface is the flow, recorded: a still hides what a click does. When the ticket adds a view, show its layout to the human as soon as it renders, before building its backend: the first look can remove it.

Add a third column, DURING DEPLOY (origin/main code reading the database the branch migrated), when the ticket has a migration, a wire/packet change, or a sidecar config change. Gateways auto-deploy and roll; that is where things break.

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.
