neo-optimize

neo-optimize is a skill for Claude Code from Parslee-ai/neo. It costs 59 tokens per session (866 once invoked), scanned A, original, Apache-2.0.

A code-optimization adviser reviews a function, file, or performance-critical code path and suggests ways to reduce unnecessary work.

In plain words
What is it for?
Use it to review measured slow code, inspect its callers, and request optimization suggestions from the configured Neo provider.
Why use it?
It helps find algorithmic, repeated-computation, memory-allocation, and tight-loop problems, while requiring measurement first so effort is spent on real bottlenecks.

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

neo-optimize 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 10d 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.

Neo Optimization Analysis

When the user invokes this skill ($neo-optimize <target>), do the following:

  1. Locate the target. It may be a function name (process_large_dataset), a file, or a description ("the user-search query path"). Use Grep/Read to find the actual implementation.

  2. Capture the current implementation plus its callers if you can do so cheaply. Neo can suggest better algorithms, but only if it sees how the code is used.

  3. Apply the provider boundary. Redact secrets, credentials, tokens, cookies, and session material. Before an external-provider call, tell the user which Neo provider will receive which files or data categories. Production, private, or customer code requires explicit authorization for that provider and scope.

  4. Invoke Neo with an optimization-framed prompt. Allow up to 5 minutes. Use Codex's approval flow for required network access, naming the provider and summarized data in the approval description.

    neo --json --no-scan --no-memory --mode advise <<'QUERY'
    Suggest optimizations for the following code. Focus on: algorithmic improvements (lower asymptotic complexity), redundant computation, allocation in hot loops, IO batching opportunities. Skip micro-style changes.
    
    <paste current implementation + relevant callers>
    QUERY
    
  5. Present Neo's suggestions ranked by expected impact. Each CodeSuggestion includes estimated_risk and blast_radius — surface those alongside the recommendation.

  6. For high-risk changes, recommend benchmarking before applying. Neo's confidence reflects pattern-match strength, not measured speedup.

--no-scan is mandatory: Codex already selected the implementation and callers, so Neo must not silently add working-directory files to the provider request. --no-memory is the default so unrelated stored facts cannot enter the provider prompt. Omit it only when the user explicitly authorizes relevant Neo memory; include stored facts as a disclosed data category.

neo-optimize is a skill published in the GitHub repository Parslee-ai/neo (16 stars, last pushed 2d ago), licensed Apache-2.0. It adds 59 tokens to every session and 866 once invoked, about $0.0003 per session on Opus 5. 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 2026-08-30.
