write

/write — Context Externalizer

Move knowledge from the context window into a structured, persistent file in .wisci/context/. This is the "save to disk" operation — preserve what would otherwise be lost to context limits or session endings.

Boundary: /write stores reusable knowledge (research, decisions, architecture notes). Session work state (goal, in-progress, next steps) belongs in /compress.

Timestamp: !date '+%Y-%m-%d %H:%M'

Execution Flow

1. Parse arguments. Read $ARGUMENTS to determine what to externalize from the current context.

2. Derive topic slug. Extract the core topic noun phrase (strip filler: "results on", "notes about"), kebab-case, lowercase, max 5 words. If the user names a target file explicitly, use it.

3. Check for existing file. Glob .wisci/context/ for the slug:

   • No match: Create Mode below.
   • Exact match, same topic: Merge Mode — read and follow references/merge-procedure.md.
   • Exact match, different topic: ask the user — merge or disambiguated new name.

4. Write to .wisci/context/<topic-slug>.md (create directories as needed).

5. Confirm. Report path, created vs merged, and a one-line content summary.

Create Mode

1. Extract and structure the information from the current context per $ARGUMENTS
2. Organize into logical ## sections
3. Build a ## References section listing every file path mentioned in the content
4. Write using the output format below

Output Format

# <Title inferred from arguments>

> Last updated by /write on <timestamp from above>
> Source: <what session context this was extracted from>
