Apply code review fixes for modular bash profile

[Copilot]

User description

Addresses all code review feedback from PR #2 review thread.

Shell Fixes

• bootstrap.sh: Change grep pattern to "# bash.d bootstrap" to match actual comment, preventing duplicate appends on re-runs
• bashrc: Preserve existing PROMPT_COMMAND and add duplicate check; add 60s throttle to bashd-self-heal to avoid per-prompt overhead
• bash_functions.d/ai.sh: Replace "$*" with "$@" in AI wrappers for proper argument handling with spaces

Python Agent Fixes

• Add stderr output before re-raising exceptions
• Improve API key error message with setup URL
• Use elif for mutually exclusive mode conditions
• Add error handling for git clone/pull/add/commit operations
• Accept multi-word prompts via nargs='+'

# Before: fails with multiple words
chat_parser.add_argument("prompt")

# After: joins args into single prompt
chat_parser.add_argument("prompt", nargs='+')
# ...
print(chat(" ".join(args.prompt), args.mode))

Housekeeping

• Add Python cache patterns to .gitignore

PR Compliance Guide 🔍

Below is a summary of compliance checks for this PR:

Security Compliance
⚪	Sensitive error leakage Description: The git commit step returns early with the full stderr message included in the returned error string, which may expose sensitive repository details (paths, author/email) to end users or logs if surfaced; sanitize or generalize error output before returning user-visible strings. agent.py [143-159] Referred Code add_result = subprocess.run( ["git", "-C", str(repo_path), "add", relative_file], capture_output=True, text=True ) if add_result.returncode != 0: error_msg = f"Failed to add file to git: {add_result.stderr.strip()}" append_memory("short_term", f"error:{error_msg}") return error_msg commit_message = f"Add function {name} via AI agent" commit_result = subprocess.run( ["git", "-C", str(repo_path), "commit", "-m", commit_message], capture_output=True, text=True ) if commit_result.returncode != 0: error_msg = f"Failed to commit changes: {commit_result.stderr.strip()}" append_memory("short_term", f"error:{error_msg}") return error_msg
	Exception detail exposure Description: On git clone/pull failures the raised CalledProcessError will include command arguments that may reveal local paths or repo slugs; catching and re-raising after printing a custom message can still leak details—consider suppressing or sanitizing sensitive parts of the exception when printing to stderr. agent.py [117-127] Referred Code try: subprocess.run(["git", "-C", str(target), "pull", "--rebase"], check=True) except subprocess.CalledProcessError as e: print(f"Error: git pull failed for {repo_slug} at {target}: {e}", file=sys.stderr) raise return target try: subprocess.run(["git", "clone", f"https://github.com/{repo_slug}.git", str(target)], check=True) except subprocess.CalledProcessError as e: print(f"Error: git clone failed for {repo_slug} at {target}: {e}", file=sys.stderr) raise

The error handling approach here is inconsistent with the git clone/pull operations above (lines 117-127). Those operations use check=True and re-raise exceptions, while this checks returncode manually and returns an error message string instead of raising an exception.

This inconsistency could lead to confusing behavior - some git failures will raise exceptions while others will return error strings. Consider using a consistent error handling strategy throughout the function. Either:

1. Use check=True for all git operations and handle exceptions at a higher level, or
2. Use capture_output=True with manual returncode checks for all git operations and return error messages

The same issue applies to the commit operation below (lines 152-159).

[Copilot]

The chat function accepts four modes ("chat", "debug", "tldr", "code") according to the argument parser (line 170), but only handles three of them. The "code" mode is missing its conditional branch, so it will use the default system prompt instead of a code-specific one.

Add an elif mode == "code": branch with an appropriate system prompt, for example:

elif mode == "code":
    system_prompt = "Assist with code generation and shell scripting; provide working examples."

Suggested change

	system_prompt = "Summarize command usage with short examples."
	system_prompt = "Summarize command usage with short examples."
	elif mode == "code":
	system_prompt = "Assist with code generation and shell scripting; provide working examples."

[Copilot]

The error handling here prints the exception details to stderr before re-raising, but then immediately re-raises the CalledProcessError which already contains the error information. When the exception propagates to the caller, the error message will be shown again by the default exception handling.

Additionally, the error message format f"Error: git pull failed for {repo_slug} at {target}: {e}" is somewhat redundant since CalledProcessError already includes the command that failed. Consider removing the stderr output and letting the exception's natural error message be displayed, or catch the exception higher up in the call chain (in main()) and format it there for user-friendly output.

[Copilot]

Same issue as with the git pull error handling above - the error message is printed to stderr before re-raising, which leads to duplicate error output. Consider a more consistent approach to error handling throughout the function.
