third-pass-deep-read

third-pass-deep-read is a skill for Claude Code, Codex from yogsoth-ai/de-anthropocentric-research-engine. It costs 113 tokens per session (521 once invoked), scanned A, original, Apache-2.0.

A detailed third reading of a research paper, done sentence by sentence and including proofs and derivations. It also attempts to mentally rebuild the paper’s method to expose hidden assumptions and possible improvements.

In plain words
What is it for?
Use it after the second-pass reading when you need a deep technical check of the paper’s reasoning, implementation, and improvement opportunities.
Why use it?
It can reveal problems or unstated assumptions that shorter readings miss. It is the final and most intensive stage of the three-pass reading method.

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

third-pass-deep-read 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

Third Pass Deep Read

Keshav's third pass: sentence-by-sentence re-read with proofs/derivations included, attempting virtual re-implementation. The heaviest pass of the three — terminal step of the Keshav cascade.

Execution

Subagent — spawned via spawn-agent skill.

Why renamed from third-pass-verify (v1's name)

v1's version of this SOP (staged/wechat-article-v1/skills/third-pass-verify/) treated this as a "targeted re-check of uncertain_fields, no-op if none flagged" step — which, per the coverage audit's S2 finding, effectively deleted Keshav's real third pass (a 4-5+ hour re-implementation attempt) and replaced it with a cheap verification step serving v1's own pipeline. This v2 SOP restores the actual third pass; the rename to third-pass-deep-read marks that this is not the same behavior as the old third-pass-verify, even though both sit in the same cascade position.

Why Subagent

A genuine re-implementation attempt needs a context that can hold the full paper and reason through design alternatives without being anchored to how pass 2 already framed the contribution.

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.
Files

What ships with it

2 files 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.
