slipway: Instructions file for Codex

AGENTS.md

slipway AGENTS.md is an instructions file for Codex, OpenCode from signalridge/slipway. It costs 470 tokens per session, scanned A, original, BSD-3-Clause.

The central principles for Slipway, a user-controlled assistant for AI coding work. They define how runs start, how user interruptions are handled, when confirmation is needed, and how agents should investigate requests.

In plain words
What is it for?
Use them when starting or controlling Slipway runs, handling skips or stops, investigating coding requests, deciding whether to ask a question, and reporting work.
Why use it?
They keep the assistant under the user’s control and reduce unnecessary questions or unsafe actions. They also make the recovery and reporting expectations consistent across the repository.

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

This is signalridge/slipway's own configuration. It tells Codex and OpenCode how to work on slipway 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 slipway 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

slipway 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 8d 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.

Slipway Agent Principles

Slipway is a user-invoked, interruptible soft autopilot for AI coding. This file states principles only. Command syntax and protocol fields belong to the CLI, the generated capabilities, and docs/reference/, not here.

This is the single principle file for every agent working in this repository. CLAUDE.md points here on purpose: two copies of these rules drifted into two different wordings once already.

User owns the process

  • Never start Slipway on its own. A run begins only from explicit user intent.
  • Honor skip, stop, resume, reorder, and manual takeover immediately. The user owes no reason.
  • Ask for confirmation before a destructive operation. Do not require repeated approval for ordinary work that was already requested.

Investigate before clarifying

  • Read the current Git state, relevant code, and repository build, test, typecheck, and lint conventions yourself.
  • Ask zero questions when the request is complete, and proceed without repeated authorization.
  • Ask only genuine human decisions that repository investigation cannot settle, one at a time, with a recommendation, rationale, and concrete alternatives.
  • If clarification changes the implementation understanding, summarize the shared understanding and obtain one confirmation before implementation.
  • Stop the interview immediately when the user asks to wrap up.

Report, do not certify

  • Record exact commands, exit codes, changed files, findings, known issues, uncertainties, and activities not performed.
  • Never present an unrun activity as run.
  • ended means the automatic Action queue is empty. It is not a judgement about the software.
  • Review is advisory and read-only. Findings never automatically trigger repair work.
  • Report state the product can honor. Do not publish authority, an Action, or an observation that the current state contradicts.

Maintain the whole surface

  • Keep the CLI, versioned protocol, host capabilities, docs, and tests consistent.
  • Preserve unrelated work and user-modified managed files.
  • Never make an agent guess its next step. A pause or error names the operation and its typed inputs; if the public surface leaves the next command to guesswork, fix that surface.
  • Do not reintroduce retired commands, ambient hooks, old-state readers, dual runtime behavior, or compatibility aliases. Remove retired behavior instead.

Changes

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.
