Finding Experiments
PostHog/posthog
Resolves a PostHog experiment reference from natural language to a concrete experiment ID by browsing experiment-list (not feature-flag tools), with disambiguation when multiple experiments match.
A skill your agent uses when Codex needs to identify missing motivation, experiments, baselines, theory, novelty, scope, limitations, or writing inputs for a PaperPRISM project.

What it does
Missing Information Detector is an agent skill from XueruiSu/Paper-PRISM. Use when Codex needs to identify missing motivation, experiments, baselines, theory, novelty, scope, limitations, or writing inputs for a PaperPRISM project.
Its SKILL.md is about 300 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
When your agent uses it
- Codex needs to identify missing motivation
- Writing inputs for a PaperPRISM project
Example prompts
- “/missing-information-detector”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Inspect the ResearchAsset, ClaimEvidenceMap, WritingPlan, draft, or review issue.
- Group gaps by motivation, task definition, method, baselines, experiments, ablations, theory, novelty, related work, limitations, and…
- Mark severity: must-fix, should-fix, or writing-only.
- Ask at most three high-value questions when user input is required.
- Update PaperState or provide a concise missing-information report.
What it can do on your machine
Read from SKILL.md and the folder at commit 13e134f. 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
Missing Information Detector loads about 296 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 120 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.
