dustbringer

dustbringer is a skill for Claude Code, Codex from Hmbown/knightsradiant. It costs 21 tokens per session (426 once invoked), scanned A, original, MIT.

A code-maintenance workflow for removing unused code, breaking up oversized parts, and reducing structural debt in a repository.

In plain words
What is it for?
Use it to prepare a simplification packet covering deletion evidence, characterization tests, the cleanup patch, phased migration details, notes, and remaining risks.
Why use it?
It replaces vague cleanup with evidence, tests, migration planning, and documented risks, so changes are easier to review and safer to inherit.

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

dustbringer 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 9d 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

Dustbringer

Delete what is dead, split what is overgrown, and pay down structural debt.

Invoke when

Follow agents/03-dustbringer/AGENTS.md for the canonical decision criteria.

Inputs required

  • task statement
  • relevant repo or diff context
  • current constraints and risk level
  • any prior hand-off artifact from the previous order

Procedure

  1. Read the canonical order doc at agents/03-dustbringer/AGENTS.md.
  2. Use the local order procedures under agents/03-dustbringer/skills/.
  3. Keep the work inside this order's stance until its artifact is complete.
  4. Hand off only after the artifact is explicit enough for the next order to inherit.

Output shape

Produce the full simplification packet defined in agents/03-dustbringer/AGENTS.md.

At minimum, include:

  • deletion ledger
  • usage evidence (specify the type: telemetry data, code grep, dependency graph, or interviews; name the source)
  • characterization tests added
  • simplification patch summary
  • migration choreography if the deletion requires phased rollout (phases, rollback triggers, observability for each phase)
  • migration notes or tombstones
  • residual risk list

Do not omit required output items from the canonical output contract, even if you summarize elsewhere.

Hand-off

  • Normal: Skybreaker
  • Exception: Elsecaller

Local doctrine

  • Order doc: agents/03-dustbringer/AGENTS.md
  • Local skill index: agents/03-dustbringer/skills/SKILL.md

Example invocation

"Use dustbringer for this task and produce the required artifact before proposing the next order."

Usage rule

Do not combine this with multiple other active order skills unless you are explicitly routing or handing off. One order should own the work at a time.

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.
