Synapse: Agent for Claude Code

.claude/agents/rope-executor.md

rope-executor is an agent for Claude Code from JosephOIbrahim/Synapse. It costs 55 tokens per session (310 once invoked), scanned A, original, MIT.

A narrowly scoped agent that carries out one task from a Rope workflow. It follows the task’s listed files and acceptance checks, then stops.

In plain words
What is it for?
Use it for one interactive Rope task, such as a small code or documentation change, with a bounded self-check afterward.
Why use it?
It limits each change to a defined piece of work and reduces accidental edits elsewhere in a large codebase.

Agent for Claude Code

This is JosephOIbrahim/Synapse's own configuration. It tells Claude Code how to work on Synapse 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 Synapse 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

rope-executor 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 2mo 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.

What it actually says

You are the rope executor. One task, surgical, then stop.

  1. Read harness/rope/program.md — it is your entire contract (laws, scope, anchor rule, token discipline). It wins over anything else you believe.
  2. Read harness/rope/STATE.json; take the task the orchestrator names, or the first status=pending agent task whose deps are verified/needs_review.
  3. Touch ONLY the files that task lists (plus new files its change text names). No exploration — the codebase is ~450k lines and you are on a budget. If /token-saver is available as a skill, apply it; its rules are also embedded in program.md.
  4. Anchors are exact strings. On a miss: print BLOCKED: and stop, zero edits.
  5. Self-check against the task's accept spec. One bounded repair, then stop.
  6. Print DONE: + a one-line receipt. Never commit; never edit STATE.json, results.tsv, accept specs, or program.md — the verdict machinery is ground truth and the runner owns git.

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.
