patch-opencode

patch-opencode is a skill for Claude Code, Codex from EZotoff/ez-omo-config. It costs 53 tokens per session (2,654 once invoked), scanned A, original, MIT.

A procedure for making a small source-code fix in the exact release version of the OpenCode program currently running.

In plain words
What is it for?
It helps identify the live version, apply a minimal fix, build the matching release, replace the program safely, and test the affected behavior.
Why use it?
It avoids replacing a stable installation with code from the wrong version and requires a backup and checks before installation.

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

patch-opencode scanned grade A with 1 finding 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 243 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Patch OpenCode Binary

This skill applies a minimal source fix to the live OpenCode binary. It builds from the exact release tag that matches the running version — never from dev or any other branch.

Pre-flight Checks

Before starting, gather the facts:

# 1. Identify the live version
LIVE_VERSION=$(~/.opencode/bin/opencode --version 2>&1)
echo "Live version: $LIVE_VERSION"

# 2. Identify the source repo
SOURCE_DIR="${OPENCODE_SOURCE:-$HOME/src/opencode}"
cd "$SOURCE_DIR"

# 3. Verify the release tag exists
git tag --list "v${LIVE_VERSION}"
# Expected: v1.17.9 (or whatever the live version is)
# If empty, the version tag doesn't exist — do NOT proceed with dev branch

# 4. Check for running servers
ps -ef | grep 'opencode serve' | grep -v grep

Critical Rules

  1. NEVER build from origin/dev or any branch other than the release tag
  2. NEVER replace the live binary with a build that reports a different version
  3. ALWAYS backup the live binary before replacing
  4. ALWAYS build with --single --skip-install --skip-embed-web-ui for speed
  5. ALWAYS verify the build version matches the live version before installing
  6. ALWAYS test the fix on the real surface after installing
  7. NEVER redirect command output into a live runtime artifact (~/oh-my-openagent-v4.19.2/dist/*, ~/.opencode/bin/*, ~/.opencode/plugin/*, ~/.config/opencode/* live configs). Diagnostic reads (git show, cat, curl) write to .sisyphus/drafts/ or a mktemp path ONLY. Live-file writes go through the documented patch flows (timestamped .pre-* backup + verify). 2026-09-08: git show <ref>:dist/index.js > dist/index.js captured its own fatal error into the live bundle and killed every fresh session for 4+ hours.

Live Patch Guard contract

The live-patch-guard plugin blocks direct binary swaps (cp/mv/install/dd targeting ~/.opencode/bin/opencode). The supported path is the transactional installer wrapper:

scripts/build-and-install-opencode.sh build
scripts/build-and-install-opencode.sh install <binary>

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.
