## Description

Ingest Pi coding-agent session history into Obsidian as distilled knowledge. Use for importing or mining ~/.pi/agent/sessions or Pi conversation logs; use wiki-agent for targeted topic-only recall.

# Pi History Ingest, Session Mining

You are extracting knowledge from the user's Pi coding agent sessions and distilling it into the Obsidian wiki. Pi sessions are stored as structured JSONL with a tree layout, your job is to follow the active branch, extract durable knowledge, and compile it.

**Session knowledge closure:** Pi session files are the only factual source for this skill. Do not add background knowledge from model training, other tools, package docs, local files, or the current conversation unless that fact appears in the selected session entries. If outside context seems useful, mark it as an open question or skip it, never present it as extracted session knowledge.

This skill can be invoked directly or via the `wiki-history-ingest` router (`/wiki-history-ingest pi`).

## Before You Start

**Writing profile:** Before drafting or rewriting natural-language Markdown, read and apply the `Writing Profile Resolution` section in `llm-wiki/SKILL.md`. Framework schema, provenance, safety, and operation-specific requirements take precedence.
`WRITING.md` preferences apply only to newly drafted or rewritten natural-language Markdown; preserve source content and structured records.

1. **Resolve config**, follow the Config Resolution Protocol in `llm-wiki/SKILL.md` (inline `@name` override → walk up CWD for `.env` → global config → prompt setup). This gives `OBSIDIAN_VAULT_PATH` and `PI_HISTORY_PATH` (defaults to `~/.pi/agent/sessions`)
2. Read `.manifest.json` at the vault root to check what has already been ingested
3. Read `index.md` at the vault root to understand what the wiki already contains

## Ingest Modes

### Append Mode (default)

Check `.manifest.json` for each source file. Only process:

- Files not in the manifest (new sessions)
- Files whose modification time is newer than `ingested_at` in the manifest

Use this mode for regular syncs.

### Full Mode
