periodic-rollup

periodic-rollup is a skill for Claude Code from nweii/agent-stuff. It costs 47 tokens per session (702 once invoked), scanned A, original, MIT.

A workflow for combining notes from shorter periods into a parent weekly, quarterly, or yearly note. It can also compile mentions of a project or topic into a history note.

In plain words
What is it for?
Use it to find related notes, synthesize their descriptions, write or update the parent note, and preserve links and related-note metadata.
Why use it?
It keeps periodic summaries connected to their source notes while preserving detail and the hierarchy from daily notes through yearly notes.

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

periodic-rollup scanned grade A with 0 findings 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 5d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Periodic rollup

Roll up periodic vault notes by synthesizing child descriptions into a parent note's description. If $ARGUMENTS is provided, use it to identify the periodic note to target.

History rollup — When asked to roll up history for a project or topic, or to compile periodic mentions into a Histories note, follow references/history-rollup.md instead of this workflow.

Workflow

  1. Gather — Search for source notes using obsidian CLI or MCP vault search
  2. Synthesize — Process gathered content according to the steps below
  3. Write — Produce or update the output note

Principles

  • Preserve source wikilinks back to origin notes for traceability
  • Respect the hierarchy: daily → weekly → quarterly → yearly
  • Preserve detail in archives; don't summarize what should be kept verbatim
  • Update related properties bidirectionally when creating new notes

Process

When generating a summary for a periodic note (weekly, quarterly, or yearly):

  1. Identify the note hierarchy

    • Determine which periodic level you're summarizing (e.g., quarterly from weeklies, weekly from dailies)
    • Locate all related child notes referenced in the related frontmatter property
  2. Extract child descriptions

    • Read the description property from each child note's frontmatter
    • These summaries usually crystallize the period's essence. However, if a description is missing, feels too vague, or if a specific day/week seems particularly significant, you are encouraged to read the original note content or sub-referenced notes to gain a more complete understanding.
  3. Scan parent note content

    • Check if the parent note has any "Notes" or remarks sections that add context the children don't capture
    • Look for emergent patterns, meta-reflections, or threads that span multiple children
    • Don't treat these as equally weighted to the children—they're supplementary unless particularly revealing
  4. Synthesize without imposing narrative

Changes

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.
