What it does
Open Loops Validate is an agent skill from real-simple-labs/parker-brain. Run a hypothesis's test plan, gather the evidence, and honestly resolve the loop into one of the four validation states — validated, invalidated, inconclusive, or insufficient evidence. Use when a hypothesis is approved or proceeding and it is time to test it, or when the user says validate this, run the test, close the loop, or what did the research find.
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files (for example `processes/INDEX.md`, `processes/re-validation.md` and `processes/resolve-the-state.md`).
It sits in Testing & QA, covering Test generation.
When your agent uses it
- A hypothesis is approved
- Proceeding and it is time to test it
- The user says validate this
- What did the research find
Example prompts
- “/open-loops-validate”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Load the canon, the brand, and the hypothesis. Read open-loops-system.md (the four states) and the hypothesis doc — its prediction, its…
- Run the plan, in its order, capturing the evidence exactly. Work each source the plan names. Capture the evidence the way the finding will…
- Run the reverse-evidence step. The plan included a step that looks for evidence against the prediction. Run it as hard as the steps that…
- Resolve the state against the pre-set bar. See processes/resolve-the-state.md. Measure what the evidence shows against the bar the…
- Write the closure document and file it. See processes/the-closure-document.md. File it under validations/[state]/[YYYY-MM]/.
- Implement the finding, spawn the next loops, then inform. This is the last stage. Based on the finding, go through the brand's docs and…
- Schedule re-validation. See processes/re-validation.md. A validated insight is stamped with how fresh it is and when it should be…
What it can do on your machine
Read from SKILL.md and the folder at commit 62c4f72. 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 (its code samples are markdown).
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
Open Loops Validate loads about 1.8k tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 917 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 917 words (~1,751 tokens).
“Run the plan in an approved hypothesis, gather the evidence honestly, and resolve the loop into one of four states: validated, invalidated, inconclusive, or insufficient evidence. Write the closure document, file it under the state it landed in, tell the…”
