ablation-execution

ablation-execution is a skill for Claude Code, Codex from yogsoth-ai/de-anthropocentric-research-engine. It costs 23 tokens per session (209 once invoked), scanned A, original, Apache-2.0.

A method for understanding a system by removing one component at a time and recording what changes.

In plain words
What is it for?
Running controlled component-removal experiments and tracking direct or cascading impacts.
Why use it?
It shows which parts matter and reveals effects caused by removing individual components.

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

ablation-execution 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

Ablation Execution

Systematically remove components from a system one by one and record the resulting changes.

Execution

Subagent — spawned via subagent-spawning/spawn-agent skill.

Why Subagent

Ablation requires careful, systematic removal of each component while tracking cascading effects. Benefits from dedicated context to maintain the full system model during iterative removal.

Available SOPs

Optional, no fixed order; the final leaf is always a sop.

SOP When to use
spawn-agent Spawn a customized CC subagent with full MCP tool access. Used by SOPs that declare execution: subagent.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
