# write-the-intel-brief Turns investigation findings into a defensible intelligence product: judgements up front, source and timestamp on every claim, observation kept apart from inference. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 1800 installs · ★ 54 - Author: UseOSINT - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/UseOSINT/Skills/tree/HEAD/skills/write-the-intel-brief/SKILL.md - Updated: 2026-08-03 - HTML: https://affpapa.org/en/nevibecode/skills/write-the-intel-brief ## What it does The skill imposes an order on report writing. Every claim is sorted into one of three buckets: observation, inference, assessment. Blur them and a conclusion slips into the text wearing the grammar of a fact. "The account is operated from Lisbon" is not the same sentence as "posting times cluster in UTC+0/+1", and only one of them holds up under questioning. Each retained claim then gets a source, a UTC retrieval timestamp, a source-reliability grade and an archive reference. For material that might become evidence, the skill adds chain of custody: who collected it, with which tool and version, plus a hash of the stored file (`sha256sum file` on Linux, `shasum -a 256 file` on macOS). Keep the original untouched and work on copies. A screenshot with no hash and no capture method is worth very little. Judgements come first: the answer to the objective question, its probability and confidence, then the two or three judgements the decision rests on. Probability draws on one ordered ladder of terms, and a numeric percentage never shares a sentence with a word from it. Confidence is a separate axis, so "highly likely, low confidence" is a legitimate and honest line when everything rests on a single unverifiable source. Negative findings and gaps belong in the body, not buried at the end, and "checked, absent" is not the same as "could not check". The source text is truncated, so read the skill itself for the full sequence. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add UseOSINT/Skills --skill write-the-intel-brief -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/write-the-intel-brief/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/write-the-intel-brief/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add UseOSINT/Skills --skill write-the-intel-brief -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/write-the-intel-brief/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add UseOSINT/Skills --skill write-the-intel-brief -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/write-the-intel-brief/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install UseOSINT/Skills write-the-intel-brief ``` 2. **Manually: put the files in place** - File: `.github/skills/write-the-intel-brief/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add UseOSINT/Skills --skill write-the-intel-brief -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/UseOSINT/Skills --path skills/write-the-intel-brief ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/write-the-intel-brief/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add UseOSINT/Skills --skill write-the-intel-brief -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/UseOSINT/Skills/tree/HEAD/skills/write-the-intel-brief/SKILL.md ## When to use it - write up an investigation so it survives cross-examination - keep observation, inference and assessment visually distinct - attach source, timestamp and archived copy to every claim - document negative findings and gaps with the scope searched - build an evidence pack with chain of custody and file hashes ## Example prompts - Turn these findings into an intel brief: judgements first, source and timestamp on every claim - Sort my investigation notes into observations, inferences and assessments - Write up the evidence pack with file hashes, chain of custody and negative findings ## Source text · SKILL.md · MIT Below is the content of a third-party file.

The failure that destroys credibility isn't a missed source — it's a sentence that reads as fact and is actually an inference. "The account is operated from Lisbon" versus "posting times cluster in UTC+0/+1, consistent with Iberian working hours." One survives cross- examination. ## Step 1 — Sort every claim into observation, inference, or assessment Three categories, never blurred, ideally visually distinct in the text. - **Observation** — what you saw, with source and timestamp. "The registry record retrieved 2024-03-11 lists A. Kestrel as director." - **Inference** — a logical step from observations, with the step shown. "The same registrant email appears on both domains, so they were registered by one party." - **Assessment** — your analytic judgement, carrying probability and confidence. "We assess it is likely the two companies are commonly controlled." Any sentence where you cannot say which category it belongs to is a sentence that has smuggled a conclusion into the evidence. Rewrite it. Verbs betray the category: *is, lists, shows* for observation; *indicates, implies* for ``` END THIRD-PARTY FILE 711c2ac9f4e7e24f The third-party file has ended.
