reflection-journal

reflection-journal is a skill for Claude Code, Codex from grcengineering/companion. It costs 55 tokens per session (463 once invoked), scanned A, original, MIT.

A guided end-of-session reflection that records what a learner understood, what remains unclear, and what to review next.

In plain words
What is it for?
Use it after a lesson, lab, scenario, or quiz when the learner wants a summary, a note to revisit, or a next review target.
Why use it?
It gives a learning session a clear conclusion instead of leaving takeaways and open questions unrecorded.

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

reflection-journal 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 1mo 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

reflection-journal

What

Close a learning session by capturing what changed, what remains unclear, and where the learner will apply the idea next.

When

  • A session is ending.
  • The learner asks for takeaways or reflection.
  • A lab, scenario, quiz, or concept session needs closure.
  • The learner wants a note they can revisit later.

Not For

  • Durable progress state. Use progress-tracker.
  • Cold-start or profile updates. Use profile-wizard or profile-refresher.
  • Operational status reporting.

Inputs

  • Current session topic and artefact, if any.
  • Learner's own stated takeaway.
  • Optional progress state.

Steps

Ask:

  1. What changed in your model?
  2. What remains unclear?
  3. Where would this show up in real work?
  4. What should we revisit next time?

Then produce a concise reflection note and optional progress update proposal.

Validation

  • The note distinguishes changed understanding from remaining confusion.
  • The next review target is explicit.
  • Any real-work application is framed as learning transfer, not advice.

Gotchas

  • If the learner wants a compliance status summary, refuse that framing and reflect on learning instead.
  • If the learner is tired, ask fewer questions and keep the note short.
  • If the reflection reveals profile change, propose it visibly rather than silently updating.

Failure Modes

  • Empty summary: require at least one learner-authored takeaway.
  • Operational drift: do not summarize programme status.
  • Lost next step: always end with a review or practice target.

Examples

  • User says "Wrap this up" -> Ask what changed, what is unclear, and what to revisit, then create a short reflection note.
  • After a lab -> Capture the artefact, the concept practised, and the next recall checkpoint.
  • User says "We are audit-ready now" -> Refuse operational status and reflect on what they learned about audit readiness patterns.
Files

What ships with it

3 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.
