edgedancer

edgedancer is a skill for Claude Code, Codex from Hmbown/knightsradiant. It costs 20 tokens per session (414 once invoked), scanned A, original, MIT.

A review role focused on overlooked situations, such as unusual inputs, failed recovery, accessibility, and slow operations. It follows project-specific instructions and produces a detailed edge-case report.

In plain words
What is it for?
Use it to examine a task and its code or changes, list missing coverage and risky paths, suggest recovery tests, and record operational or accessibility concerns when relevant.
Why use it?
It helps find problems that normal implementation checks may miss, especially when software fails or is used in less common ways.

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

edgedancer 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 5d 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

Edgedancer

Cover the forgotten paths: edge cases, error recovery, accessibility, slow paths.

Invoke when

Follow agents/04-edgedancer/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/04-edgedancer/AGENTS.md.
  2. Use the local order procedures under agents/04-edgedancer/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 edge-path packet defined in agents/04-edgedancer/AGENTS.md.

At minimum, include:

  • edge-case matrix (include time horizon: immediate, hours, days, weeks)
  • coverage present vs missing
  • highest-risk forgotten paths
  • a11y findings if relevant
  • recovery-path tests to add
  • operational recovery notes (rollback runbook entries, on-call guidance) if the edge case is production-facing
  • patch recommendations

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

Hand-off

  • Normal: Dustbringer
  • Exception: Truthwatcher

Local doctrine

  • Order doc: agents/04-edgedancer/AGENTS.md
  • Local skill index: agents/04-edgedancer/skills/SKILL.md

Example invocation

"Use edgedancer 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.

edgedancer is a skill published in the GitHub repository Hmbown/knightsradiant (2 stars, last pushed 4mo ago), licensed MIT. It adds 20 tokens to every session and 414 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
