claudeception

claudeception is a skill for Claude Code, Codex from topprismdata/cultivating-ml-agent. It costs 96 tokens per session (1,899 once invoked), scanned A, original, MIT.

A guide for turning useful discoveries from Claude Code work sessions into reusable skills for future sessions.

In plain words
What is it for?
Use it to review a session, classify what was learned, and create a skill describing a bug fix, best practice, or workflow.
Why use it?
It prevents non-obvious fixes, workarounds, and lessons from being lost after a debugging session ends.

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

claudeception 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 8d 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.

Claudeception

Continuous learning system that extracts reusable knowledge from work sessions into Claude Code skills. Each extracted skill makes future sessions smarter.

When to Extract

Extract when you encounter:

  1. Non-obvious solutions — Required >10 min investigation, not in docs
  2. Error resolution — Misleading error messages, non-obvious root causes
  3. Workaround discovery — Tool/framework limitations requiring experimentation
  4. Configuration insights — Project-specific setups differing from standard
  5. Trial-and-error success — Multiple approaches before finding what worked
  6. Self-critique catches — A predicted risk actually materialized (high-value signal)
  7. Path efficiency insights — A systemic execution pattern worth improving

Dual-Track Classification

Before creating, classify the knowledge:

Track When Template sections
Bug fix Defect, failure, error resolution Problem, Symptoms, Root Cause, Solution, Prevention
Knowledge Best practice, pattern, workflow optimization Context, Guidance, Why This Matters, When to Apply

This determines the skill's section structure.

Extraction Process

Step 1: Overlap Detection (BEFORE creating)

Search existing skills for overlap across 5 dimensions:

Dimension What to compare
Problem statement Same underlying issue?
Root cause Same technical cause?
Solution approach Same fix?
Referenced files Same code paths?
Prevention rules Same advice?

Scoring: Count matching dimensions.

Overlap Action
High (4-5 match) Update existing skill with fresher context
Moderate (2-3 match) Create new, add See also: cross-reference
Low (0-1 match) Create new normally

Why: Two skills describing the same problem will drift apart. Update rather than duplicate.

Step 2: Research (When Appropriate)

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.

claudeception is a skill published in the GitHub repository topprismdata/cultivating-ml-agent (5 stars, last pushed 11d ago), licensed MIT. It adds 96 tokens to every session and 1,899 once invoked, about $0.0005 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.
