OpenCode 编码代理

委派编码任务给 OpenCode CLI（功能开发、PR 审查）

OpenCode CLI

Use OpenCode as an autonomous coding worker orchestrated by Hermes terminal/process tools. OpenCode is a provider-agnostic, open-source AI coding agent with a TUI and CLI.

使用场景

前置条件

Binary Resolution (Important)

Shell environments may resolve different OpenCode binaries. If behavior differs between your terminal and Hermes, check:

terminal(command="which -a opencode")
terminal(command="opencode --version")

If needed, pin an explicit binary path:

terminal(command="$HOME/.opencode/bin/opencode run '...'", workdir="~/project", pty=true)

One-Shot Tasks

Use opencode run for bounded, non-interactive tasks:

terminal(command="opencode run 'Add retry logic to API calls and update tests'", workdir="~/project")

Attach context files with -f:

terminal(command="opencode run 'Review this config for security issues' -f config.yaml -f .env.example", workdir="~/project")

Show model thinking with --thinking:

terminal(command="opencode run 'Debug why tests fail in CI' --thinking", workdir="~/project")

Force a specific model:

terminal(command="opencode run 'Refactor auth module' --model openrouter/anthropic/claude-sonnet-4", workdir="~/project")

Interactive Sessions (Background)

For iterative work requiring multiple exchanges, start the TUI in background:

terminal(command="opencode", workdir="~/project", background=true, pty=true)
# Returns session_id

# Send a prompt
process(action="submit", session_id="", data="Implement OAuth refresh flow and add tests")

# Monitor progress
process(action="poll", session_id="")
process(action="log", session_id="")

# Send follow-up input
process(action="submit", session_id="", data="Now add error handling for token expiry")

# Exit cleanly — Ctrl+C
process(action="write", session_id="", data="x03")
# Or just kill the process
process(action="kill", session_id="")

Important: Do NOT use /exit — it is not a valid OpenCode command and will open an agent selector dialog instead. Use Ctrl+C (x03) or process(action="kill") to exit.

TUI Keybindings

Resuming Sessions

After exiting, OpenCode prints a session ID. Resume with:

terminal(command="opencode -c", workdir="~/project", background=true, pty=true)  # Continue last session
terminal(command="opencode -s ses_abc123", workdir="~/project", background=true, pty=true)  # Specific session

Common Flags

Procedure

PR Review Workflow

OpenCode has a built-in PR command:

terminal(command="opencode pr 42", workdir="~/project", pty=true)

Or review in a temporary clone for isolation:

terminal(command="REVIEW=$(mktemp -d) && git clone https://github.com/user/repo.git $REVIEW && cd $REVIEW && opencode run 'Review this PR vs main. Report bugs, security risks, test gaps, and style issues.' -f $(git diff origin/main --name-only | head -20 | tr 'n' ' ')", pty=true)

Parallel Work Pattern

Use separate workdirs/worktrees to avoid collisions:

terminal(command="opencode run 'Fix issue #101 and commit'", workdir="/tmp/issue-101", background=true, pty=true)
terminal(command="opencode run 'Add parser regression tests and commit'", workdir="/tmp/issue-102", background=true, pty=true)
process(action="list")

Session & Cost Management

List past sessions:

terminal(command="opencode session list")

Check token usage and costs:

terminal(command="opencode stats")
terminal(command="opencode stats --days 7 --models anthropic/claude-sonnet-4")

Pitfalls

Verification

Smoke test:

terminal(command="opencode run 'Respond with exactly: OPENCODE_SMOKE_OK'")
