opencode-repo-setup-skill

opencode-repo-setup-skill is a skill for OpenCode from darellchua2/opencode-config-template. It costs 64 tokens per session (2,493 once invoked), scanned B, original, Apache-2.0.

An interactive setup guide for enabling selected MCP servers and related options for one OpenCode project. MCP servers are tools that an agent can connect to, while CodeGraph builds a project code map.

In plain words
What is it for?
Use it to configure a repository’s opencode.json, optionally initialize CodeGraph, and add project rules to AGENTS.md.
Why use it?
It avoids changing global settings and makes project-specific tool choices, token costs, and rollback steps explicit.

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 B, and why

opencode-repo-setup-skill scanned grade B with 2 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 4d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- **"Backend: wasm" (5–10x slower)** — install native build tools (`sudo apt install build-essential python3 make`; macOS: `xcode-select --install`), then `npm rebuild better-sqlite3`. Also fixes **"database is locked"**

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- Headless fallback = skip MCP, use REST: token at id.atlassian.com/manage-profile/security/api-tokens (scoped tokens must use `api.atlassian.com/ex/jira/{cloudId}`; unscoped use site-direct `/rest/api/3/`), auth via `cu

How it starts

The opening of the file, as written. The whole thing — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What I do

I am the interactive frontend for per-project MCP enablement. The global deploy ships most MCP servers disabled (zero always-on schema cost); this skill is how a specific repo opts in. I run in the primary session of the TARGET project (not the configurator repo):

  1. Detect — scan the repo for setup signals
  2. Ask — present a question-tool menu of opt-in servers + extras
  3. Write — merge-write ONLY the delta into <repo>/opencode.json
  4. Init — optionally run codegraph init -i
  5. Report — enabled set, estimated token cost, revert instructions

I never edit the global ~/.config/opencode/config.json. Opencode merges project config over global with project wins semantics, so a one-key delta is all that's needed.

When to use me

  • User says "set up MCP for this repo", "enable Jira/Atlassian here", "project-level opencode setup"
  • A marker rule fired (user AGENTS.md may say: if a repo's AGENTS.md mentions Jira/MCP needs, offer this skill)
  • First session in a repo that carries its own .opencode/ — offer to review/extend it

Step 1 — Detect

Cheap, read-only scans (no network):

Signal Check Suggests
Existing project config <repo>/opencode.json exists Idempotent mode: show current overrides, offer to extend
CodeGraph index <repo>/.codegraph/ exists codegraph already enabled locally; no action
Jira usage AGENTS.md/README mentions Jira keys (PROJ-123), JIRA env vars, atlassian refs offer atlassian enable
GitHub-centric .github/, gh in scripts gh CLI usually suffices; no MCP needed
Docs-heavy .docx/.pptx/.pdf in repo offer markitdown/docling packs
Frontend package.json with next/react offer next-devtools
Python pyproject.toml nothing MCP-specific by default

Report findings in one table, then go to Step 2.

Step 2 — Ask (question tool)

One multi-select question + one yes/no per extra. Options are built from the detection table — only show servers with a detected signal plus the general opt-in list:

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-repo-setup-skill is a skill published in the GitHub repository darellchua2/opencode-config-template (6 stars, last pushed yesterday), licensed Apache-2.0. It adds 64 tokens to every session and 2,493 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
