activity

activity is a skill for Claude Code from anthonysuherli/br8n. It costs 83 tokens per session (545 once invoked), scanned A, original, MIT.

A skill for querying an activity knowledge graph, a connected record of repositories, branches, files, work sessions, and tasks across projects.

In plain words
What is it for?
It is for finding recent work, related files and tasks, or a cross-repository summary of activity, optionally narrowed to one repository.
Why use it?
It makes it easier to reconstruct what you have been working on across multiple repositories instead of checking each project separately.

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

activity 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.

What it actually says

br8n — Activity

The cross-repo lens. While /br8n:pickup replays one repo+branch, activity answers "what have I been doing, everywhere" — backed by a knowledge graph that accumulates automatically on every br8n_capture. Nothing to build; just query.

The graph's ontology: repo, branch, file, session, task nodes, related by on_repo, on_branch, in_repo, edited, viewed, pursued.

Step 1 — Query the graph

Call mcp__plugin_br8n_br8n__br8n_activity:

  • A natural-language query seeds a semantic subgraph ("what touches the store layer", "the KG work"). Omit it for the whole (capped) graph.
  • Optional repo narrows to one repository.

It returns {nodes, edges, summary}summary is a ready-to-show natural-language rollup; nodes/edges are the graph slice for anything more detailed.

Step 2 — Answer

Lead with the summary (repos, tasks, files in view). Then, if the user wants specifics, read the nodes/edges:

  • Tasks (type: task) — the intents pursued, distilled from hypotheses.
  • Sessions (type: session) — individual captures; properties carry captured_at, repo, branch, hypothesis.
  • Files (type: file) — what was edited vs. viewed (the edge relation).
  • Follow edited/pursued/on_repo edges to connect a file or task back to the repos and sessions that touched it.

When to reach elsewhere

  • Single repo+branch "where was I" → /br8n:pickup (richer card for the here-and-now).
  • A question needing external knowledge → /br8n:search (grounds + fills the gap).

The activity graph is read-only here — it grows on its own as captures happen.

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.
