What it does
Dossier is an agent skill from borghei/Claude-Skills. Structured intelligence dossiers on companies, people, markets, or domains, with source triangulation and fact/inference discipline. Use when preparing a deal-prep dossier, executive briefing, or due-diligence overview.
Its SKILL.md is about 2k 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 `references/dossier-frameworks-and-structure.md`, `references/fact-vs-inference-discipline.md` and `references/source-triangulation-and-reliability.md`).
It sits in Business, Finance & HR, covering Fundraising and pitch decks and Sales call preparation. The repository describes itself as: 385 AI skills, 77 expert agents, and 900 stdlib Python tools for every team: engineering, PM, marketing, C-level, compliance, business ops, research, and a LinkedIn toolkit… The licence is MIT.
When your agent uses it
- Preparing a deal-prep dossier
- Executive briefing
- Due-diligence overview
Example prompts
- “/dossier”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Specify subject type + purpose.
- Run dossier_outline_generator.py to produce a structured outline
- Assign owners + research targets per section.
What it can do on your machine
Read from SKILL.md and the folder at commit 4a698e8. 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 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
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
Dossier loads about 2k tokens when it runs, and up to ~6.8k if it reads all its reference files. Until then it costs about 57 tokens; SKILL.md has 815 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.

Intelligence Dossier
A research skill for producing structured intelligence dossiers — the kind of document a CEO reads before a meeting, a PM reads before market-entry, or an investor reads before due diligence.
When to use this skill
- Deal-prep dossier before a major partnership / acquisition meeting
- Executive briefing ahead of a board, customer, or regulator meeting
- Market-entry analysis for a new geography or vertical
- Due-diligence overview for investment or M&A consideration
- Competitor profile in depth
- Person dossier ahead of executive recruiting or board engagement
Inputs the advisor expects
- Subject (company / person / market / domain)
- Purpose (deal-prep, due diligence, briefing — affects depth + emphasis)
- Audience (exec, board, working team)
- Timeline / deadline
- Known starting sources
- Sensitive areas to dig into
Clarify First
Before building the dossier, confirm these inputs. If any is unknown or vague, ASK — do not assume:
- Subject + subject type (company / person / market) — selects the outline template and which sections apply
- Purpose (deal-prep, due diligence, briefing, market-entry) — drives depth, emphasis, and the Implications section
- Audience (exec, board, working team) — sets altitude and length of the executive summary
- Key decision or risk to inform — drives the Risks + Open Questions and Recommendations sections
Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.
Workflows
Workflow 1 — Generate dossier outline
- Specify subject type + purpose.
- Run
dossier_outline_generator.pyto produce a structured outline tailored to subject + purpose. - Assign owners + research targets per section.
python3 dossier/scripts/dossier_outline_generator.py \
--subject-type company --purpose deal-prep --format markdownWorkflow 2 — Validate source triangulation
- Capture claims with supporting sources.
- Run
source_triangulation_validator.pyto check each claim has multiple independent supporting sources + source reliability. - Flag thinly-sourced claims for additional research.
python3 dossier/scripts/source_triangulation_validator.py \
--input claims_with_sources.json --format markdownWorkflow 3 — Separate facts from inferences
- Capture dossier statements.
- Run
fact_inference_separator.pyto classify each statement and flag unsupported inferences.
python3 dossier/scripts/fact_inference_separator.py \
--input dossier_statements.json --format markdownDecision frameworks
The dossier hierarchy
A useful structure for any dossier:
- Executive summary (1 page, lead with takeaway)
- Subject overview (facts: what they are)
- Context (market, history, environment)
- Capabilities + assets (what they can do)
- People + leadership (who runs it)
- Performance + trajectory (numbers, trends)
- Relationships + ecosystem (who they're with)
- Risks + open questions (what we don't know)
- Implications + recommendations (so what)
- Sources + methodology (how we know)
Fact vs inference discipline
Three categories per statement:
| Category | Definition | Example |
|---|---|---|
| Fact | Verifiable, sourced | "Founded 2018; HQ in Chicago" |
| Inference | Reasoned from facts | "Likely targeting enterprise segment based on hiring pattern" |
| Speculation | No supporting evidence | "Might pivot to AI next year" |
A trustworthy dossier separates these clearly. Mixing them = loss of credibility.

Source reliability scoring (Admiralty Code adapted)
| Reliability | Code | Description |
|---|---|---|
| Completely reliable | A | Established, history of completely reliable info |
| Usually reliable | B | History of mostly reliable info |
| Fairly reliable | C | History of reliable info with notable errors |
| Not usually reliable | D | Limited history; mixed accuracy |
| Unreliable | E | Known for inaccurate info |
| Cannot be judged | F | New / unknown source |
| Information credibility | Code | Description |
|---|---|---|
| Confirmed | 1 | Confirmed by other independent sources |
| Probably true | 2 | Not confirmed; consistent with other info |
| Possibly true | 3 | Not confirmed; reasonable but unsupported |
| Doubtful | 4 | Inconsistent with other info |
| Improbable | 5 | Contradicted by other info |
| Cannot be judged | 6 | New info; no validation possible |
A "B-2" rated claim is "usually reliable source, probably true" — workable. An "F-6" claim is "unknown source, unverified" — barely worth including.
Triangulation principle
For each significant claim:
- 1 source: anecdotal; flag explicitly
- 2 independent sources: workable (most dossier claims should reach this)
- 3+ independent sources: confirmed; safe to assert
"Independent" means not derived from the same underlying source. Two news articles citing the same press release ≠ 2 independent sources.
Common engagements
"Build a dossier on company X before our acquisition meeting"
- Run outline generator (subject=company, purpose=deal-prep).
- Pull: financials, leadership, products, customers, IP, tech stack, regulatory posture.
- Identify red flags: undisclosed litigation, key person dependencies, customer concentration, regulatory risk.
- Recommendations: questions to ask in meeting; deal structure implications.
"Executive briefing for senator's office meeting"
- Run outline (subject=person/organization, purpose=briefing).
- Pull: voting record, recent statements, committee assignments, donor profile, alignment with our position.
- Anticipate likely questions; prepare positions.
"Market-entry analysis for [country]"
- Run outline (subject=market, purpose=market-entry).
- Pull: market size, growth, competitive landscape, regulatory, distribution, cultural / business norms, talent.
- Compare entry options (direct, partner, acquisition).
Anti-patterns to avoid
- Mixing facts + inferences without labels. Reader can't calibrate trust.
- Single-source claims presented as confirmed. Anecdote dressed as data.
- Unsourced "everyone knows" claims. Often turn out wrong.
- Padding with low-relevance facts. Bloated dossier loses signal.
- Burying risks at the end. Risks should be surfaced upfront.
- No update mechanism. Stale dossier on important subject = bad decisions.
- Adversarial language about subject. Bias erodes credibility.
