CodexConnector: Instructions file for Claude Code

CLAUDE.md

CodexConnector CLAUDE.md is an instructions file for Claude Code from ffaheem88/CodexConnector. It costs 1,166 tokens per session, scanned A, original, Apache-2.0.

Project instructions for CodexConnector, covering its code-review and planning commands. Code review means checking code changes for bugs, edge cases, and improvements before finishing.

In plain words
What is it for?
They guide agents reviewing feature, bug-fix, and refactoring changes, including prioritising issues and repeating reviews until no significant problems remain.
Why use it?
They provide a repeatable review loop so problems found after implementation can be fixed and checked again.

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

CodexConnector CLAUDE.md 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 2mo 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.

Claude Code Instructions

CodexConnector Workflow

CodexConnector has two actions: review (review code changes) and plan (get feedback on a plan before implementing it).


1. Code Review Workflow

After completing any code changes (features, bug fixes, refactors), you MUST run the Codex review process before considering the task done.

Process

  1. Run the review after making changes:

    codex-review "Review the changes I just made for bugs, edge cases, and improvements"
    

    If the project spans multiple repos in the same parent directory, review them all:

    codex-review -d /path/to/parent-folder "Review all changes across repos"
    
  2. Analyze the feedback from Codex and identify:

    • High priority issues (bugs, crashes, security issues)
    • Medium priority issues (edge cases, error handling)
    • Low priority issues (style, naming, best practices)
  3. Fix the issues starting with high priority, then medium, then low.

  4. Re-run the review after fixes:

    codex-review "Verify the fixes address the previous issues"
    
  5. Repeat steps 2-4 until Codex reports no significant issues remaining.

When to Stop

The review loop is complete when:

  • No High or Medium priority issues remain
  • Codex confirms the code is satisfactory
  • Only optional/stylistic suggestions remain (which can be noted but not necessarily fixed)

2. Plan Review Workflow

Before implementing a bug fix or a new module, you SHOULD run the Codex plan review to get feedback on your approach.

When to Use

  • Planning a bug fix and want a second opinion on the approach
  • Designing a new module or feature and want architectural feedback
  • Evaluating whether an implementation plan accounts for edge cases
  • Checking if a proposed change will conflict with existing code

Process

  1. Write the plan — either as a file or describe it inline:
    # From a plan file
    codex-review -a plan -f plan.md
    
    # Inline description
    codex-review -a plan "Fix the race condition in the worker pool by adding a mutex around the shared counter and draining the channel before shutdown"
    
    # Both: plan file with extra focus instructions
    codex-review -a plan -f plan.md "Focus on thread safety concerns"

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.
