What it does
Meridian Evidence is an agent skill from rynfar/meridian. Adversarially review Meridian or scrub changes and preserve reproducible E2E, headless, and visual proof for PRs, critical fixes, merges, and releases.

It sits in Testing & QA, covering End-to-end testing. It works with Claude Agent SDK, Google Gemini and Model Context Protocol. The repository describes itself as: Use Claude and Antigravity with Pi, OpenCode and other coding clients. Local API bridge, usage dashboard and Mac app. Antigravity preview available in 1.74.0.
When your agent uses it
- Tasks that involve End-to-end testing
Example prompts
- “/meridian-evidence”
What it can do on your machine
Read from SKILL.md and the folder at commit 6e510db. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Meridian Evidence loads about 1.1k tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 579 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 579 words (~1,060 tokens).
“Use this for every proposed PR and release in the Meridian family, and for issue fixes whose behavior must be demonstrated. Read the target repo's AGENTS.md, its validation scripts, and Meridian's E2E cases when affected. Match the test to the…”
