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

managing-custom-fields 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 10d 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

Managing Custom Fields

Workflow

  1. Discover existing fields

    astravue_get_custom_fields — list fields for a project or get values for a specific task.

  2. Set a field value

    • For dropdown fields, call astravue_list_custom_field_options first to find valid options
    • astravue_set_custom_field_value — set the value on a task
    • Value format depends on field type: strings for text, true/false for checkbox, yyyy-MM-dd for date, option name or ID for dropdowns

  3. Create a new field

    • astravue_create_custom_field — define field name, type, and scope (project or space)
    • For dropdown types, add options with astravue_create_custom_field_option
    • Supported types: SINGLE_LINE_TEXT, MULTI_LINE_TEXT, NUMBERS, DATE, PHONE, EMAIL, CHECKBOX, SINGLE_SELECT_DROPDOWN, MULTI_SELECT_DROPDOWN, PERCENTAGE, CURRENCY, URL

  4. Delete fields or options

    • astravue_delete_custom_field_option — remove a dropdown option (can migrate tasks to a replacement)
    • astravue_delete_custom_field — remove the field and all its values from every task in scope

    Always confirm deletions with the user. These actions cannot be undone.

Important

  • Max 5 fields per type per scope
  • Requires space admin (space-level) or project admin (project-level) permissions for create and delete operations
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.
