adept-self-improve

adept-self-improve is a skill for Claude Code from itaywol/adeptability. It costs 48 tokens per session (588 once invoked), scanned A, original, MIT.

A workflow for turning durable lessons, corrections, and project conventions into reusable skills. It also synchronizes those skills across supported coding environments.

In plain words
What is it for?
Use it when a user corrects a recurring practice, a general fix is discovered, or a project convention should be remembered for future work.
Why use it?
It prevents useful corrections and working practices from being forgotten after the current session.

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

adept-self-improve 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Self-improve: turn lessons into skills

adept skills are portable memory. A lesson written as a skill is loaded by every harness on every future session — not lost when this context ends. When you learn something durable, capture it instead of forgetting it.

When to capture

Capture when the lesson is durable and reusable, not one-off:

  • The user corrects you ("we always use X, not Y", "don't touch Z").
  • A fix or pattern generalizes beyond the file you're in.
  • You discover a project convention the code doesn't make obvious (a build gate, a naming rule, a required pre-PR step).
  • You catch yourself thinking "I'll remember that for next time." — you won't; the skill will.

Don't capture: secrets, one-shot facts, anything already obvious from the code or existing skills. Improve an existing skill before adding a near-duplicate (adept skill list).

The loop

adept skill list                       # does a skill already cover this? edit it if so
adept skill add <kebab-id> --edit      # else scaffold a new one
# write a triggering description + a tight, harness-neutral body
adept sync                             # render to every enabled harness
adept status && adept diff             # confirm it landed clean

Then tell the user, in one line, what you captured and where — they own the memory, so let them veto it. Commit the new skill with their normal review.

What makes a captured lesson good

  • Description = trigger. Front-load when it applies so a future agent loads it at the right moment. See [[authoring-adept-skills]] for crafting the description and activation.
  • Atomic. One lesson per skill. If it needs "and also…", it's two skills.
  • Reason, not just rule. "Use sentinel errors so callers can errors.Is" beats "use sentinel errors" — the why survives refactors the rule wouldn't.

Confirm before you persist

Capturing is an outward, durable act: it changes how every future session behaves. Surface what you're about to write and let the user confirm — don't silently rewrite the project's shared memory. See [[using-adept]] for the surrounding CLI.

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.
