improve

improve is a command for Claude Code from samibs/skillfoundry. It costs 0 tokens per session (3,197 once invoked), scanned A, original, MIT.

A command that repeatedly scans a codebase for improvement opportunities, fixes them, and scans again until the work is complete or its limit is reached.

In plain words
What is it for?
Use it to inspect or fix selected improvement areas, preview changes with a dry run, continue an interrupted run, set an iteration budget, or open a pull request.
Why use it?
It helps address architectural issues, duplicate code, quality problems, and security concerns in an ongoing cycle instead of one review at a time.

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

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 yesterday.

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.

The opening of the file, as written. The whole thing — 388 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/improve — Continuous Improvement Loop

Scans the codebase for improvement opportunities, fixes them one at a time, and loops until no improvements remain or the token budget is exhausted.

This is Boris Cherny's "agent prompting itself" pattern applied to codebase health: the agent scans → prioritizes → fixes → checkpoints → scans again. No human input between iterations.

Protocol engine: agents/_ralph-loop-protocol.md + agents/_self-prompt-protocol.md


Usage

/improve                    Scan and fix all improvement categories
/improve arch               Architectural improvements only
/improve duplication        Duplicate code / abstraction consolidation
/improve quality            Code quality (GuardLoop patterns GL-01 through GL-10)
/improve security           Security posture improvements
/improve --dry-run          Show what would be fixed, do not apply any changes
/improve --resume           Resume a previously interrupted improvement loop
/improve --budget [N]       Set max iterations (default: 10)
/improve --pr               Open a PR with all fixes when the loop completes

What This Command Does

This is a self-prompting loop — the agent finds the work, does the work, finds more work, and stops when there is nothing left.

LOOP {
  1. SCAN       — Identify all improvement opportunities in scope
  2. PRIORITIZE — Rank by impact, select the single highest-priority item
  3. FIX        — Apply the fix (surgical — one item per iteration, no scope creep)
  4. VERIFY     — Confirm the fix did not regress anything
  5. CHECKPOINT — Record: what was fixed, what remains, what was learned
  6. JUDGE      — Any improvements remaining? Budget sufficient to continue?
  7. SELF-PROMPT — Formulate: "I fixed X. Still need to address Y at [location]."
  8. → RE-ENTER at step 2 with that self-prompt as current_task
}

EXIT when:
  - Backlog is empty (no improvements remain in scope)
  - Token budget < 20% remaining
  - Max iterations reached
  - Same item appears in remaining work twice with no change (oscillation)
  - An item cannot be fixed without user input (blocked)

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.

improve is a command published in the GitHub repository samibs/skillfoundry (12 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,197 tokens. 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 2026-09-03.
