This benchmark measured an earlier version of the skill.
A newer attempt on gemini-3.8-flash on 10/18/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
One of 9 test cases the skill fixed. Same model, same prompt, with and without the skill.
After processing a Pi session file, what top-level JSON key and per-file `source_type` value must be stored in `.manifest.json`?
| Checked | Without skill | With skill |
|---|---|---|
| Stores top-level session aggregation metrics under the pi key in .manifest.json. | Missed | Passed |
| Sets source_type: pi_session on processed file entries in .manifest.json. | Passed | Passed |
The instructions your model reads when the skill loads.
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).
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.
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).manifest.json at the vault root to check what has already been ingestedindex.md at the vault root to understand what the wiki already containsCheck .manifest.json for each source file. Only process:

Process everything regardless of manifest. Use after wiki-rebuild or if the user explicitly asks for a full re-ingest.
Pi stores sessions under ~/.pi/agent/sessions/ (or the path set by PI_CODING_AGENT_SESSION_DIR).
