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

inbox 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.

/inbox — Quick Capture & Process

Dual-mode command for fast capture and later processing.

Context

Today's date: !date +%Y-%m-%d Inbox contents: !ls 00-inbox/*.md 2>/dev/null

Reference template: @_templates/inbox.md Config: @_core/config.yaml Processing logic: @_core/PROCESSING.md

Input

User input: $ARGUMENTS

Mode Detection

  • Capture mode: If $ARGUMENTS has content
  • Process mode: If $ARGUMENTS is empty

Capture Mode (with content)

  1. Auto-detect

    • Project: Look for project names from config
    • Type: daily, decision, blocker, meeting, doc
  2. Create Inbox Note

    • Filename: 00-inbox/{date}-{slug}.md
    • Tag with detected project/type
    • Status: unprocessed
  3. Append to Vault Log

    • Append entry to 01-index/_vault-log.md (see .claude/rules/vault-log.md)
    • Action: inbox-capture
    • Details: what was captured and detected type
  4. Output

    Captured to: 00-inbox/{filename}
    Detected: {project} / {type}
    Process later with: /inbox
    

Process Mode (no content)

Use session tasks for batch visibility:

TaskCreate: "Scan and classify inbox items"
  activeForm: "Scanning inbox..."

TaskCreate: "Route items to destinations"
  activeForm: "Routing inbox items..."
  1. Scan Inbox

    • List all .md files in 00-inbox/
    • Read and classify each
  2. Present Plan

    ## Processing Plan
    
    | # | Content Preview | Type | Project | Action |
    |---|-----------------|------|---------|--------|
    | 1 | "Shipped login..." | daily | project-a | Update daily |
    | 2 | "Blocked on API..." | blocker | project-a | Create blocker |
    
    Proceed? (y/n/edit)
    
  3. Route Items

    • For each confirmed item:
      • Route to appropriate handler (/daily, /block, /decide, etc.)
    • Mark processed inbox files
  4. Append to Vault Log

    • Append one inbox-route entry per batch to 01-index/_vault-log.md (see .claude/rules/vault-log.md)
    • Details: count of items routed and their types

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.
