## What it does

The skill reads an investigation log and answers from it, so the attorney does not have to re-read every entry. Ask about one person's account, about where the complainant and the respondent disagree, about what is still missing, or about the strongest evidence on a given issue.

Three steps run inside. It loads the `internal-investigation` reference skill and runs Mode 3 (Query). Every answer cites the log entry IDs behind it. When the log holds nothing on the topic, the skill says so outright and offers to flag it as a gap.

You call it as a slash command with two arguments: the matter name and your question. Leave out the matter name and nothing runs, since that is how the right log gets found. Citation rules and gap-flagging templates live in the reference skill, which has to be loaded before any substantive work.

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/anthropics/claude-for-legal/tree/HEAD/employment-legal/skills/investigation-query/SKILL.md

## When to use it
- find out what the respondent said about a specific event
- spot where the complainant's and respondent's accounts conflict
- work out which materials the matter still needs
- pick the strongest evidence on each issue
- get an answer tied to log entry IDs instead of a recap from memory

## Example prompts
- /employment-legal:investigation-query [matter name] What did the respondent say about the December team dinner?
- /employment-legal:investigation-query [matter name] Where do the complainant's and respondent's accounts conflict?
- /employment-legal:investigation-query [matter name] What do we still need?

# /investigation-query

Answers questions against the investigation log — what witnesses said,
where accounts conflict, what gaps exist, what the strongest evidence is
on each issue.

## Instructions

1. Load the `internal-investigation` reference skill and run Mode 3 (Query).
2. Always cite log entry IDs in the answer.
3. If the log contains nothing relevant to the question, say so explicitly —
   "I have not seen any information on [topic] in this investigation log
   ([N] entries reviewed)" — and offer to flag it as a gap.

## Examples

```
/employment-legal:investigation-query [matter name]
What did the respondent say about the December team dinner?
```

```
/employment-legal:investigation-query [matter name]
Where do the complainant's and respondent's accounts conflict?
```

```
/employment-legal:investigation-query [matter name]
What do we still need?
```

> Detailed log-query process, citation rules, and gap-flagging templates live
> in the `internal-investigation` reference skill — load it before doing
> substantive work.
