claudeception

claudeception is a skill for Claude Code, Codex from divinevideo/divine-mobile. It costs 36 tokens per session (962 once invoked), scanned A, original, MPL-2.0.

A dated journal for recording lessons from debugging, workarounds, and investigations. Entries are saved under /.codex/journal for later searching or separate promotion into reusable guidance.

In plain words
What is it for?
Use it after non-obvious debugging, trial-and-error fixes, misleading errors, or newly discovered project constraints.
Why use it?
It prevents useful discoveries and the reasons behind them from being lost after a work session. It also keeps personal notes separate from permanent skills.

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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/claudeception-activator.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Claudeception captures episodic memory from work sessions.

It does not create or update skills. Its job is to preserve what happened, what was learned, and why it mattered in a dated journal entry that can be searched later or promoted through a separate workflow.

When To Use

Use this skill when any of these are true:

  • A task required non-obvious debugging or investigation
  • A workaround or recovery path was discovered through trial and error
  • An error message was misleading and the real root cause was learned
  • A project-specific or system-specific constraint was uncovered
  • The user asks /claudeception
  • The user says "save this as a skill", "extract a skill from this", or "what did we learn?"

Do not use this skill to create durable procedural knowledge. If the learning should become a reusable skill, leave that for a separate promotion step.

Core Rule

Never create a skill from this skill.

Even when the user says "save this as a skill", honor the intent by writing a journal entry unless they explicitly ask for a separate skill-writing workflow.

Capture Threshold

Write a journal entry when the session produced knowledge that is worth preserving, even if it is narrow or specific to one system.

Good journal material:

  • Incident-specific discoveries
  • System quirks and deployment gotchas
  • Root causes behind confusing failures
  • Investigated tradeoffs and workarounds
  • Repeated patterns that are not generalized yet

Skip capture when:

  • The task was a routine documentation lookup
  • The conclusion is already covered cleanly by an existing skill or project docs
  • The note would mostly restate obvious knowledge
  • The note would require storing secrets or sensitive internal details

Output Location

Write entries to:

~/.codex/journal/YYYY-MM-DD-topic-slug.md

Examples:

  • ~/.codex/journal/2026-04-05-fastly-draft-version-publish-mismatch.md
  • ~/.codex/journal/2026-04-05-nextjs-server-side-error-debugging.md

If multiple notes land on the same date with the same slug, add a short suffix.

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.
