Research Ops is an agent skill from ericrisco/rsc-harness. Use when someone hands you an open question whose answer must survive scrutiny — a tech choice, a regulation, a what-is-actually-true-about-X — with every non-obvious claim dated and sourced, source disagreements surfaced rather than averaged away, and a cited memo as the deliverable. Also for refreshing a stale research memo. NOT sizing a market with TAM/SAM/SOM (that is market-research), NOT a standing cadence watch on named rivals (that is competitor-watch).
Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `evals/README.md`, `evals/cases.yaml` and `references/credibility-rubric.md`).
It sits in Marketing & SEO, covering Market research and Market sizing. The repository describes itself as: Your agent invents things because it has no memory, and can't touch your database because it has no arms. rsc is the meta-harness that gives it both, plus the trade to know the… The licence is MIT.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit e3d5b33. 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.
Ships 1 file in scripts/ (Shell), which the agent can run.
From 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 loads about 2.9k tokens when it runs, and up to ~4.6k if it reads all its reference files. Until then it costs about 121 tokens; SKILL.md has 1,439 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); the scripts in this folder are not scanned.

.claude/skills/research-ops/SKILL.md (or your agent's skills folder). This skill also uses 5 other files; get the full folder from GitHub.You are the method, not the topic. Someone hands you "go find out about X" and you hand back a memo where every load-bearing claim traces to a source, a date, and a confidence tier — a document that survives someone reading it adversarially. The topic changes every time; the procedure does not.
Two hard rules, stated up front because everything else hangs off them:
Research is an ordered loop, not a lookup. Run it in this order; each step has a reason.
[source, date, confidence], with an explicit "couldn't verify" section. Why: the memo is the
deliverable; the searches were just inputs.Stop rule: stop when new searches stop changing the answer (coverage plateaus) OR the budget cap is hit — whichever comes first. Looping forever is not rigor.
Refuse to start on an underspecified question. Researching a fuzzy ask produces a fuzzy memo and wastes the search budget. Before the first query, get the 2–3 answers that change which sources are even relevant.
Bad (will waste the budget): "What car should I buy?"
Good (scopeable): "Best used EV under €25k for a 40km daily commute,
bought in Spain in 2026, prioritizing range over trim."The clarifiers that almost always matter: constraint (budget / scale / tolerance), context (where, for whom, what stack), and time ("as of when" — 2026 answers differ from 2023 ones). If the asker can't answer them, ask; don't guess and research the wrong thing.
Not every source counts the same. Restrict to primary / authoritative sources where you can — official docs, standards bodies, regulator pages, company release notes, filings, the actual paper. When a claim lives only in secondary commentary, it drops a confidence tier. Pick the credibility check by source type:
| Source type | Check to apply | Default confidence |
|---|---|---|
| Official docs, standards, regulator, filing, release notes | SIFT — Trace to original; you are already at it | High |
| Peer-reviewed / scholarly / formal document | CRAAP (Currency, Relevance, Authority, Accuracy, Purpose) | High once it passes |
| Trade press / reputable news, corroborated by another | SIFT — Find better coverage, confirm elsewhere | Medium |
| Single blog, vendor marketing, forum post, uncorroborated | SIFT — Investigate the source; treat as a lead, not a fact | Low |
| AI summary / search snippet | Not a source — open the page it cites | None until traced |
Lateral reading is the non-negotiable move. To judge a page, leave it: open a new tab and check what others say about the author/org rather than trusting the page's account of itself. A site's "About" page is not evidence the site is authoritative. Full SIFT/CRAAP walkthrough, lateral-reading recipe, and worked tier examples live in references/credibility-rubric.md.
Every non-obvious claim carries a date, because "true" has a shelf life — a 2024 pricing fact or API behaviour may be wrong in 2026. Record both dates when they differ:
Provenance line grammar (the contract the verify gate checks):
CLAIM — [Source title](https://url), pub 2026-04-12 / accessed 2026-06-02 · confidence: highIf a source carries no discernible date, that's a finding in itself: record pub: n/a,
keep the access date, and drop it a tier. Stale → re-verify: when refreshing an old
memo, re-run the loop on the dated claims; don't just copy yesterday's citation forward.
Full skeleton and grammar: references/memo-template.md.
A claim is load-bearing if the answer changes when it's wrong. Triangulate every one against ≥2 independent sources — independent meaning they don't both trace back to the same origin (three blogs quoting one press release is one source, not three).
When sources disagree, surface the disagreement; never average it away. "Source A says X, source B says Y, here's why and which I weight higher" is a finding. Splitting the difference into a number neither source supports is a fabrication. If you genuinely find no disagreement, say so explicitly — silence reads as "didn't check."
This is why the memo is structured claim → source → date → confidence rather than as flowing prose: roughly 15–20% of AI research reports contain an error a human catches on review, and they can only catch it if each claim is individually checkable.
The memo is the deliverable. Structure it so the answer arrives first and the evidence backs it up — not a link dump the reader has to assemble themselves.
## Answer
<the direct answer in 2–4 sentences; the bottom line up front>
## Findings
- <claim> — [Source](url), pub YYYY-MM-DD / accessed YYYY-MM-DD · confidence: high|med|low
- <claim, triangulated> — corroborated by [A](url, date) and [B](url, date) · confidence: high
## Disagreements
- <where sources conflicted, and how you weighted them> — or "none found across N sources"
## Open questions / could not verify
- <what you could not source; what's still an assumption; what would settle it>The "Open questions / could not verify" section is mandatory and is not a sign of failure — it's the honest boundary of what the evidence supports. A memo with no open questions on a hard topic is usually a memo that stopped looking.
Cap effort so the loop terminates. Sensible defaults for an on-demand run:
| Anti-pattern | Why it fails | Do instead |
|---|---|---|
| One search, then reason over the snippets | That's a guess with footnotes, not research | Run the loop: re-query on every gap |
| Citing the search-result snippet | Snippets drop caveats, dates, numbers | Fetch and cite the actual page |
| Single-source claim presented as fact | One source can be wrong or biased | Triangulate load-bearing claims across ≥2 independent sources |
| Averaging two contradicting sources | Invents a number neither source supports | Surface the disagreement and weight it |
| Trusting a page's self-description | "About us" is not evidence of authority | Lateral-read: check the org elsewhere |
| Undated citation | A 2023 fact may be false in 2026 | Record pub + accessed date on every claim |
| No confidence tier | Reader can't tell a filing from a forum post | Tag high/med/low per finding |
| No "could not verify" section | Hides the boundary of the evidence | Always include open questions |
| Synthesizing before reading | Conclusion drives the search, not the evidence | Read first, conclude after |
| Infinite search, no stop rule | Burns budget, never ships the memo | Cap searches; stop at coverage plateau |
| Topic-creep into market sizing | That's a different skill's job | Route TAM/SAM/SOM to ../market-research |
| Re-citing a stale memo unchanged | Yesterday's source may be outdated | On refresh, re-verify the dated claims |
The memo is a checkable artifact, so there's a gate for it. Run it against the produced memo (read-only; it never edits):
./scripts/verify.sh --path memo.md # check one memo
./scripts/verify.sh --path research/ # scan a directory of memosIt asserts the memo has an answer/summary section, that every finding line carries a citation token, that every citation carries a date, that a confidence tier appears, and that an "Open questions / unverified" section exists. A missing or empty target is a SKIP, not a failure. The gate proves the memo is sourced and dated — it does not judge whether the answer is correct; that's the capability eval's and your job.

Going by SKILL.md and its folder, Research Ops needs a shell for the scripts in its folder. Our summary lists: A Bash shell.
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. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Research Ops is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.9k 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. Its references folder adds about 1.7k tokens, read only when the agent opens those files.
