dossier

dossier is a skill for Claude Code from eins78/agent-skills. It costs 94 tokens per session (6,150 once invoked), scanned A, original, MIT.

A structured research workflow for investigating a topic or comparing options. It gathers evidence, evaluates it, and produces a cited report or recommendation.

In plain words
What is it for?
Use it for technical research, market surveys, background briefs, state-of-the-art reviews, and evidence-based comparisons across domains such as travel, health, finance, or policy.
Why use it?
It helps turn a broad research request into a defined question and keeps the supporting evidence with the final result. It also separates neutral surveys from reports that rank and recommend choices.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dossier scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/archive-source.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Dossier

Structured research producing cited, well-edited reports. Two genres: research dossiers that map the state of a topic so the reader draws their own conclusions, and decision dossiers that rank options and recommend one. Optional decision ballots. Works for any domain — tech, travel, health, policy, finance, art.

Pick the genre before researching — it changes every stage below. Getting it wrong is the most expensive error this skill can make: it is invisible until delivery, and it cannot be patched by editing, because the two genres want different documents built from the same facts.

Workflow: SCOPE → GATHER → EVALUATE → SYNTHESIZE → REVIEW → DELIVER

0. Preflight — verify the request is actionable, and settle the genre

Before starting research, confirm all three:

  1. Specific — what to investigate is bounded: a named topic, a concrete comparison, or a clear question. "Look into the X space generically" fails this.
  2. Unambiguous — contested terms are defined by context. If the request uses a word with multiple plausible meanings and context doesn't resolve which, flag it.
  3. Well-understood — you can state the objective back to the operator in 1–2 sentences without hedging. If you'd have to pad with "I think you mean…" or "depending on what you want from this…", you don't understand it yet.

If one or more checks fail, ask before starting. A dossier built on unclear objectives wastes more research time than the clarifying turn costs. Batch questions; offer choices where reasonable; skip the obvious.

Then settle the genre — a fourth, independent check:

  1. Genre — does the reader want to learn the state of a topic and conclude for themselves, or to be handed a ranked recommendation? Infer it when the request makes it obvious; ask when it doesn't.
Request Genre Why
"brief me on the CMS MCP landscape" Research Asks about the world
"which CMS should we standardise on?" Decision Asks for a choice
"research X and tell me if we should do it" Research + assessment Explicitly both
"evaluate this pitch" Ask Evaluate reads both ways: "tell me if it's good" and "tell me about this space so I can judge"
"what are my options for X?" Ask Could be a survey of the field or a shortlist to pick from

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dossier is a skill published in the GitHub repository eins78/agent-skills (2 stars, last pushed yesterday), licensed MIT. It adds 94 tokens to every session and 6,150 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls).
