opencode

A way to delegate coding work to OpenCode, an open-source command-line AI coding agent. It supports feature work, code refactoring, pull-request review, and longer coding sessions when OpenCode is installed and authenticated.

In plain words
What is it for?
Use it to implement features, refactor code, review pull requests, or run autonomous coding tasks in a Git repository.
Why use it?
It lets another coding agent handle a task or work for longer without requiring every edit to be directed manually. It also supports running separate coding tasks in isolated workspaces.

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

opencode 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 yesterday.

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.

OpenCode CLI

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

When to Use

  • User explicitly asks to use OpenCode
  • You want an external coding agent to implement/refactor/review code
  • You need long-running coding sessions with progress checks
  • You want parallel task execution in isolated workdirs/worktrees

Prerequisites

  • OpenCode installed: npm i -g opencode-ai@latest or brew install anomalyco/tap/opencode
  • Auth configured: opencode auth login or set provider env vars (OPENROUTER_API_KEY, etc.)
  • Verify: opencode auth list should show at least one provider
  • Git repository for code tasks (recommended)
  • pty=true for interactive TUI sessions

Binary Resolution (Important)

Shell environments may resolve different OpenCode binaries. If behavior differs between your terminal and the agent, 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="<id>", data="Implement OAuth refresh flow and add tests")

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

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

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

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.

opencode is a skill published in the GitHub repository moltis-org/moltis (2,841 stars, last pushed 4d ago), licensed MIT. It adds 36 tokens to every session and 1,858 once invoked, about $0.0002 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.
