Research Ops Skills is an agent skill from alirezarezvani/claude-skills. Use when planning, funding, scoping, or synthesizing enterprise research across workstreams — clinical study design, R&D program finance, market sizing/surveys, or product/user research. Triggers on "design this clinical study", "what sample size", "R&D budget", "burn rate", "capitalize or expense", "TAM SAM SOM", "market sizing", "survey design", "segment the market", "plan user interviews", "usability test", "synthesize research insights". Forks context to route to one of four Research-Operations sub-skills…
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Product & Project Management, covering User research, Market sizing and Experimental design. The repository describes itself as: 380 Claude Code skills & agent skills & plugins (30+ Agents, 70+ custom commands, 380+ skills, customizable references, scripts)for Claude Code, Codex, Gemini CLI, Cursor, and 8… The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 19392f7. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
python3From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Research Ops Skills loads about 2.8k tokens when it runs. Until then it costs about 211 tokens; SKILL.md has 1,184 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.
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.

.claude/skills/research-ops-skills/SKILL.md (or your agent's skills folder).The Research Operations surface is how the enterprise plans, funds, scopes, and synthesizes research across four workstreams: clinical R&D, R&D finance, market research, and product research. This orchestrator forks its context, routes your inquiry to one of four sub-skills, then returns a digest. Heavy intake (protocol drafts, program ledgers, survey exports, interview transcripts) stays in the forked context.
This is the enterprise counterpart to the academic research/ domain. If your question is about finding literature, grants, or patents, use research/. If it is about planning, funding, scoping, or synthesizing research as an operational discipline, you are in the right place.
| Symptom | Sub-skill |
|---|---|
| "We're designing a Phase 2 trial — what's the endpoint and sample size?" | clinical-research |
| "What's our R&D program burn, and is this cost CapEx or OpEx?" | research-finance |
| "What's the TAM for this product, and how do we survey the segment?" | market-research |
| "How many users do we interview, and how do we synthesize the findings?" | product-research |
Same two-signal threshold pattern as commercial-skills. Single-signal → clarifying question. Mixed signals → highest-confidence first, chain second in a follow-up turn. Never silently chain.
| Signal class | Keywords | Sub-skill |
|---|---|---|
| CLINICAL | clinical trial, study design, protocol, endpoint, sample size, power, phase 1/2/3, biostatistics, eligibility, feasibility, estimand | clinical-research |
| RD_FINANCE | R&D budget, program budget, burn, runway, F&A, indirect rate, overhead, capitalize vs expense, R&D capex, portfolio ROI, rNPV | research-finance |
| MARKET | TAM, SAM, SOM, market sizing, survey design, sampling, margin of error, segmentation, competitive intelligence, market research | market-research |
| PRODUCT | user interview, JTBD, usability test, concept test, prototype test, discovery research, research repository, insight synthesis, saturation | product-research |
Derived from Matt Pocock's grill-with-docs pattern: explore-then-ask, one question per turn with a recommended answer, walk the decision tree depth-first, track dependencies, anchor every challenge in the research canon (references/ of each sub-skill).
Check the user's working directory first:
clinical-research, no question needed)?protocol.json → clinical; program-budget.json → finance; tam-model.json → market; interview-guide.md → product)?If the workspace resolves the lane, route silently.
Matt's rule: never bundle. Always recommend.
Pattern:
Q1/1: [precise question naming the two candidate lanes]
Recommended: [Lane X, because <signal-table rationale>]
(Confirm, or override?)If the inquiry legitimately crosses two lanes (e.g., "design this trial AND budget it" = CLINICAL + RD_FINANCE), walk depth-first:
Never silently chain.
Forward original prompt + structured inputs (protocol JSON, program ledger CSV, market model, observation export).
≤ 200 words: analyzed, top 3 findings (anchored to a canon citation), top 3 next actions (named human owner where applicable), artifact path, and one grill challenge for the user. Examples:
Grill the user on lane-defining decisions before invoking the sub-skill. One per turn, recommended answer, canon citation:
Never run a sub-skill until the lane-defining decision is locked.
Before invoking a sub-skill for the first time in a workspace, point the user at that skill's onboarding questionnaire so the tools run pre-configured to their context:
python3 skills/<sub-skill>/scripts/onboard.py # interactive Q&A
python3 skills/<sub-skill>/scripts/onboard.py --show # questions + current configEach sub-skill has its own question set (clinical: area/alpha/power/dropout/owners · finance: area/F&A/runway/standard/owner · market: profile/confidence/MoE/method · product: profile/insight-threshold/method/stakes). Answers persist to ~/.config/research-ops/<sub-skill>.json (or ./.research-ops/<sub-skill>.json with --scope project) and are consumed automatically by every tool in that skill. Customization is mandatory discipline here, not decoration — surface the onboarding step when a user starts a fresh research workstream.
Each sub-skill ships its own skills/<sub-skill>/scripts/ar_evaluator.py — an isolated bridge to engineering/autoresearch-agent. Invoke autoresearch only when the user explicitly asks to "optimize", "improve", or "run a loop". The handoff is per-skill (no shared coupling): the loop edits the skill's input file and the evaluator scores it (clinical → feasibility_composite higher; finance → runway_months higher; market → tam_divergence lower; product → validated_insights higher). Never auto-start a loop; never let the loop edit the evaluator.

Going by SKILL.md and its folder, Research Ops Skills needs the command-line tools its instructions call (python3). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
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. Review the folder before installing.
Research Ops Skills is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.8k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
