synergy: Instructions file for Codex

AGENTS.md

synergy AGENTS.md is an instructions file for Codex, OpenCode from SII-Holos/synergy. It costs 2,875 tokens per session, scanned A, original, MIT.

Repository instructions for Synergy, a Bun and TypeScript monorepo—a single repository containing multiple related packages. They require work to be based on current code, tests, schemas, contracts, and documentation.

In plain words
What is it for?
Use them before architecture work or package edits to find the right documentation, inspect related areas, follow workspace rules, and run the required verification.
Why use it?
They reduce accidental breakage across packages and help protect existing checkouts, running services, and package boundaries.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions subagents; mentions AGENTS.md; mentions Codex.

This is SII-Holos/synergy's own configuration. It tells Codex and OpenCode how to work on synergy itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything synergy configures →

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

synergy AGENTS.md 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 2d 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.

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.

Synergy Repository Rules

Bun/TypeScript monorepo rules. Read the nearest package AGENTS.md before editing code. Rules link their rationale. Placement and budgets follow docs/AGENTS.md.

Work from Current Evidence

  • Verify implementation, tests, schemas, generated contracts and CLI before editing.
  • Use Scope for workspace resolution/context and Library for the knowledge subsystem. Keep retired names inside docs/migrations/ or docs/research/ only.
  • Start architecture work at docs/README.md, then read only the relevant document.
  • Inspect adjacent domains before assuming ownership.
  • Keep a nearest AGENTS.md in every workspace package; update it when that package's ownership, public boundary, or verification commands change.
  • Fix root causes; preserve unrelated work and avoid opportunistic cleanup.

The project-local architecture skill provides the code-tracing workflow and links canonical documents instead of duplicating them.

Protect Checkouts and Runtimes

Checkouts and active Synergy runtimes may be shared.

  • Inspect git status, the current branch, and the worktree list before editing or performing Git operations. Direct edits in the current checkout are allowed; preserve unrelated dirty and untracked files.
  • Do not run git checkout/git switch or rebase a shared checkout unless the user explicitly requests it; these change state observed by every session using that directory.
  • Use a task-owned worktree when concurrent work needs branch or file isolation; reuse an existing task worktree when it already owns the branch.
  • Stage and commit only when the user requests it. Local commits on dev or main are permitted but advance a shared branch and must never be pushed directly; publish a topic branch and open its PR against dev. Release is the only path from dev to main.
  • Preserve unrelated dirty and untracked files; inspect status again before staging and stage only files owned by the current task.
  • Do not use destructive Git commands, force pushes, or hook bypasses without explicit user authority and a reviewed recovery plan.
  • Push, open a PR, or mutate external systems only when the user requests that action.
  • A pull request whose intent corresponds to a BlueprintLoop is accepted only when that loop reached completed through blueprint_loop_approve. An executor's self-assessment, or a loop that stalled in auditing, failed, or was rejected without a fresh audit, is not acceptance. State the loop's final status and audit conclusion in the pull request body.
  • Keep local/runtime paths, session/Scope IDs, logs, credentials, and private endpoints out of commit messages, PR bodies, comments, and reviews. Every agent-created commit uses a concise conventional type and the Co-authored-by: synergy-agent <[email protected]> footer.
  • Never stop, restart, signal, or modify the SYNERGY_HOME of the Synergy instance carrying the current task.
  • Run source changes in an isolated second home with explicit alternate ports. Load develop-synergy for the exact workflow.

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.
