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

rondo CLAUDE.md 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 8d 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.

  • Components: Bubbles v1.0.x (list, viewport, help, key, textinput)
  • Styling: Lip Gloss v1.1.x (including lipgloss/table for styled CLI tables)
  • Forms: Huh v0.8.x (task add/edit dialogs)
  • CLI Framework: Cobra v1.10.x (subcommands, flags, completions)
  • Database: SQLite via modernc.org/sqlite (CGO-free)
  • Terminal Detection: charmbracelet/x/term (width), go-isatty (TTY detection)

Key Dependencies (go.mod)

Application Features

Task Management

  • CRUD: Create, view, edit, and delete tasks
  • Subtask Support: Tasks can have subtasks with independent completion state
  • Status Tracking: Cycle tasks between Pending, In Progress, Done
  • Tab Navigation: All / Active / Done tabs with counts
  • Task Details: Right panel shows description, subtasks, progress bar
  • Date Tracking: Automatic creation date + optional due date
  • Sorting: Sort by creation date (F1), due date (F2), or priority (F3)
  • Search: Fuzzy search/filter via built-in bubbles list filtering
  • Priority Levels: Low, Medium, High, Urgent with color coding
  • Tags: Comma-separated tag support
  • Recurring Tasks: Daily, weekly, monthly, or yearly recurrence; auto-spawns next occurrence on completion
  • Task Dependencies: Block tasks by other task IDs; CLI via --blocks flag on add/edit, --clear-blocks on edit
  • Delete Guard: Refuses to delete tasks that block others; CLI returns exit code 1 unless --cascade; TUI shows yellow warning dialog requiring double-confirm
  • Self-Block Guard: Store-level rejection of self-referential dependencies
  • Metadata: Structured key-value pairs (--meta key=value) stored as JSON; filterable with AND logic via rondo list --meta key=value
  • Time Logging: Log time spent on tasks with optional notes

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.
