fix: replace hardcoded opencode path with dynamic binary discovery in query scripts

[Shaglock]

Summary

• Replace hardcoded ~/.opencode/bin/opencode path with a multi-strategy binary discovery function in both query-opencode.sh and query-opencode-history.sh
• Fix trailing whitespace throughout both scripts

Motivation

The query scripts previously hardcoded the OpenCode binary path to $HOME/.opencode/bin/opencode. Users who install OpenCode via Homebrew, pip, or other package managers would get "CLI not found" errors. This mirrors the same fix already applied to the Swift app (see AGENTS.md reflection: "Dynamic Binary Search for External Dependencies").

Changes

scripts/query-opencode.sh and scripts/query-opencode-history.sh

Both scripts receive the same find_opencode_bin() function with three discovery strategies:

1. command -v opencode — checks the current PATH (works for most installations)
2. Login shell PATH — runs $SHELL -lc 'which opencode' to pick up PATH additions from .zshrc/.bashrc that aren't in the current environment
3. Hardcoded fallback paths — tries common installation locations in order:
   • /opt/homebrew/bin/opencode (Apple Silicon Homebrew)
   • /usr/local/bin/opencode (Intel Homebrew)
   • $HOME/.opencode/bin/opencode (OpenCode default)
   • $HOME/.local/bin/opencode (pip/pipx)
   • /usr/bin/opencode (system-wide)

Error messages now go to stderr and suggest checking PATH rather than pointing to a single hardcoded location.

Whitespace cleanup

Trailing whitespace removed from ~20 lines across both scripts. No functional changes.

Files Changed

File	Change
scripts/query-opencode.sh	+44/-3 — add find_opencode_bin(), update error messages
scripts/query-opencode-history.sh	+62/-21 — add find_opencode_bin(), update error messages, whitespace cleanup

This PR updates the shell scripts to dynamically locate the opencode binary using multiple strategies (current PATH, login shell, and standard fallback locations) instead of relying on a fragile hardcoded path.

Bro, finally killing those hardcoded paths—about time.

The discovery logic matches the app's Swift implementation perfectly (checking which, login shell, then common paths), which is great for consistency.

One gotcha though: you have set -e enabled at the top. If find_opencode_bin returns 1 (not found), the line OPENCODE_BIN=$(find_opencode_bin) will cause the script to exit immediately and silently. Your nice error message block below it (Error: OpenCode CLI not found...) will never actually run.

Quick fix:

OPENCODE_BIN=$(find_opencode_bin || true)

This lets the script survive the assignment failure so it can meaningful scream at the user in the next block.

🤖 OP.GG DevOps AI Code Review

The changes successfully align the shell scripts with the main application's logic by implementing dynamic binary discovery. This significantly improves robustness for users who install opencode via Homebrew or other non-standard paths, as recommended in AGENTS.md.

The logic handles both Bash and Zsh environments correctly, and the fallback strategies cover the most common installation scenarios on macOS.

This function is identical to the one in scripts/query-opencode-history.sh. If more scripts are added in the future, consider extracting this logic into a shared scripts/common.sh file and sourcing it to reduce duplication and maintenance overhead.
