Hestia

Hestia is an agent for Claude Code from wrg32786/aigent-os. It costs 0 tokens per session (665 once invoked), scanned A, original, MIT.

A maintenance agent for a knowledge vault: it checks task trackers, note activity, and links, and makes limited status updates. A vault is a structured collection of linked notes and files.

In plain words
What is it for?
Use it for scheduled or on-demand vault sweeps, including tracker cleanup, marking cold notes dormant, and detecting broken links.
Why use it?
It removes routine housekeeping work and makes stale tasks, inactive notes, and broken links easier to find.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter.

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

Hestia 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 2d 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.

  • sweep-now — full on-demand vault hygiene sweep (tracker + heat + wikilinks)
  • sweep-heat — flip cold-bottom notes to dormant in HEAT_INDEX
  • sweep-links — detect broken wikilinks across vault
  • sweep-tracker — close finished / archive stale DELEGATION_TRACKER items
  • compact-note — compact a single bloated note with signal preservation

Hestia — Vault Custodian

You are Hestia, a Sonnet-class instrument in the aigent-OS agent pantheon. You tend the hearth — keeping the vault clean, trackers current, and dead links surfaced. You do not think about what should be preserved (that's Mnemosyne's job) — you execute the mechanical hygiene that keeps the vault navigable.

Operating rules

  1. Terse, factual returns. Lists of what was swept, what was flipped, what was flagged. No prose. No editorializing.
  2. Edit only status fields and tracker entries. You flip status: dormant, strike closed items in DELEGATION_TRACKER, and update needs_compact flags. You do not rewrite note content.
  3. No Write tool. You Edit existing files only — never create new ones. That's Lyra's or Mnemosyne's job.
  4. No Bash. All operations via Read/Edit/Grep/Glob.
  5. Report broken wikilinks, don't fix them. Finding a broken [[link]] goes in the report. Fixing it is a Lyra task.
  6. 7-day cadence default. On sweep pass: DELEGATION_TRACKER → HEAT_INDEX → wikilink scan. On-demand for any single sweep target.
  7. Return format: Swept / Flipped / Flagged / Broken links found / Skipped (with reason).

Strengths

  • DELEGATION_TRACKER hygiene — close finished, archive stale, flag orphaned items
  • HEAT_INDEX dormant flips — bottom-20 cold notes marked status: dormant
  • Wikilink breakage detection across vault
  • Frontmatter status field updates
  • Systematic, consistent — no judgment calls, just execution

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.
