alive-capture

alive-capture is a skill for Claude Code, Codex from alivecontext/alive. It costs 21 tokens per session (489 once invoked), scanned A, original, MIT.

A way to save outside information in an organized knowledge bundle. It accepts content such as emails, transcripts, screenshots, documents, and research, then records its source and type.

In plain words
What is it for?
Use it to capture external content, choose where it belongs, rename unclear files, store screenshots, update a manifest, and extract useful items into the active bundle.
Why use it?
It prevents useful context from being lost in pasted messages, random filenames, or separate files. It also helps separate raw material from extracted decisions, tasks, insights, and quotes.

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

alive-capture 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 4d 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

Capture Context

External content arrives -- email, transcript, file, research output. Route it into the system.

Detect Content Type

  • Pasted text, forwarded message -> extract and store
  • File path mentioned -> read and classify
  • Research results from a cron or web search -> structure and route
  • Screenshot -> store in bundle raw/

Route Decision

This looks like [type]. Route it?
  1. Add to [active bundle] raw/
  2. Create new bundle for it
  3. Route to [suggested walnut]
  4. Just stash it for now

Capture Process

  1. Name the file. Date-prefixed, descriptive: 2026-04-07-witcheer-feedback.md
  2. Store in bundle raw/. Write the content to the active bundle's raw/ directory.
  3. Update manifest. Add to sources: in context.manifest.yaml:
sources:
  - path: raw/2026-04-07-witcheer-feedback.md
    description: Telegram feedback on ALIVE x Hermes spec
    type: document
    date: 2026-04-07
  1. Extract stash items. Any decisions, tasks, insights, people mentions, or sharp quotes get stashed.
  2. Rename garbage filenames. CleanShot 2026-02-23... becomes 2026-02-23-descriptive-name.ext. Preserve original in manifest as original_filename:.

If No Bundle Active

Ask which walnut this belongs to, then offer to create a bundle or add to an existing one.

If No Walnut Active

Check 03_Inbox/ for unrouted files. Enter inbox scan mode -- present each file with routing suggestions.

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.
