record-a-lesson

record-a-lesson is a command for coding agents from initialneil/project-with-reflect. It costs 32 tokens per session (500 once invoked), scanned A, original, MIT.

A command for saving a lasting project note, such as a result, rule, reference, or evaluation report, in the project's permanent memory.

In plain words
What is it for?
It is for recording experiment results, settled practices, decisions, links, and other information that the project should retain.
Why use it?
It keeps useful decisions and findings available after the current session instead of leaving them only in a temporary chat or log.

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

record-a-lesson 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 4d 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

Run the record action of the current project's project-with-reflect skill with arguments: $ARGUMENTS

Resolve the project from the current directory first: match $PWD against registry.json projects' repo / dir (the project whose repo or state dir contains $PWD). If none matches, ask which project — don't guess. (Same cwd→registry match /log-and-reflect and the auto-log hook use.) Then follow <project_dir>/SKILL.md's record action.

record persists a durable thing to permanent memory now — distinct from note (an ephemeral log line) and reflect (the end-of-session sweep). It's flexible (not experiment-specific): infer or take the kind and land it in the right flat lessons/<descriptive>.md — most often by updating / editing / appending an existing lesson, a new file only when nothing fits —

  • result / benchmark / eval report → a record lesson (lessons/experiment-GUAVA.md) — accumulates, append-only;
  • rule / must-follow practice / settled conclusion → a distilled lesson (lessons/<topic>.md, bounded) + decisions.md if it's a decision;
  • reference / resource / link → a notes lesson (lessons/resources.md), or the global knowledge/<k> (/register-knowledge + use-knowledge) if broadly reusable;
  • research report / review / etc. → its own lesson; anything else durable → the closest fit.

If it continues an existing lesson, follow that lesson's established format (its sections / columns / artifact embedding) so entries stay uniform and comparable — for any kind, not just experiments. One thing → its home; archives nothing. Use it the moment a durable result lands, or when the user says "record <X>" (optionally "as a <kind>").

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.
