What it does
Evidence Selfloop is an agent skill from WILLOSCAR/research-units-pipeline-skills. Evidence self-loop for surveys: read evidence bindings + evidence packs, then write an actionable upstream TODO plan (which stage/skill to fix) before writing more prose.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/run.py`).
The repository describes itself as: Research pipelines as semantic execution units: each skill declares inputs/outputs, acceptance criteria, and guardrails. Evidence-first methodology prevents hollow writing…
Example prompts
- “/evidence-selfloop”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit c92912a. 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
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
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
Evidence Selfloop loads about 2k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 846 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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 846 words (~2,013 tokens).
“Purpose: make the evidence-first pipeline converge without writing filler prose.”

Evidence Selfloop is an agent skill from WILLOSCAR/research-units-pipeline-skills. Evidence self-loop for surveys: read evidence bindings + evidence packs, then write an actionable upstream TODO plan (which stage/skill to fix) before writing more prose.
How do I install Evidence Selfloop in Claude Code?
Run `npx skills add WILLOSCAR/research-units-pipeline-skills --skill evidence-selfloop -a claude-code`. Or copy the skill folder (.codex/skills/evidence-selfloop in WILLOSCAR/research-units-pipeline-skills) into .claude/skills/evidence-selfloop in your project. Claude Code loads it when a task matches its description.
How do I install Evidence Selfloop in Codex?
Run `npx skills add WILLOSCAR/research-units-pipeline-skills --skill evidence-selfloop -a codex`. Or copy the skill folder (.codex/skills/evidence-selfloop in WILLOSCAR/research-units-pipeline-skills) into .agents/skills/evidence-selfloop in your project. Codex loads it when a task matches its description.
Can I use Evidence Selfloop in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add WILLOSCAR/research-units-pipeline-skills --skill evidence-selfloop -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/evidence-selfloop, .gemini/skills/evidence-selfloop, .github/skills/evidence-selfloop and .opencode/skills/evidence-selfloop in your project.
What does Evidence Selfloop need to run?
Going by SKILL.md and its folder, Evidence Selfloop needs Python for the scripts in its folder and the command-line tools its instructions call (uv). Our summary lists: Python 3.
Does Evidence Selfloop access the network?
SKILL.md contains no URLs. Its commands use uv, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Evidence Selfloop safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Evidence Selfloop use?
No licence was found for Evidence Selfloop or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Evidence Selfloop use?
About 2k tokens (SKILL.md is roughly 8.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Evidence Selfloop?
