AgentAction AGENTS.md is an instructions file for Codex, OpenCode from dinpd/AgentAction. It costs 586 tokens per session, scanned A, original, Apache-2.0.

Delivery instructions for the AgentAction repository, covering the required path from an issue to a merged change. They also define how to classify release impact and when to follow the project's release process.

In plain words
What is it for?
Use it for every software change in AgentAction, especially changes to user-visible behavior, APIs, command-line behavior, schemas, authorization, evidence, or migrations.
Why use it?

Written for Codex and OpenCode: the file is AGENTS.md.

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

AgentAction 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 18d 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.

AgentAction Delivery Instructions

Follow the issue-to-merge workflow for every software change in this repository. Preserve unrelated local changes and do not report completion until the remote default branch contains the verified change.

Public demo addresses

Use an agentaction.dev subdomain for public demo entrypoints and promotional links in documentation, the website, posts, and videos. Name the subdomain for the specific demo; do not use a generic demo hostname. Configure and verify HTTPS before promotion. Use https://shared-authority.agentaction.dev/ for shared authority and https://refund.agentaction.dev/ for the original refund demo. Keep signed provider/issuer identifiers stable unless their migration is explicitly part of the task.

Release responsibility

Classify the release impact before implementing each change and record it in the issue and pull request.

A change is significant functionality when it adds or materially changes a user-visible capability, public API, CLI behavior, schema, package export, authorization or evidence behavior, hosted gateway contract, or required migration. Significant functionality must execute the release process in docs/releasing.md in the same delivery task unless the user explicitly narrows the task to an earlier gate. Do not wait for the user to remember or separately request the release.

Use a minor release for significant functionality while the project is below 1.0, a patch release for backward-compatible fixes, and a prerelease when the release policy identifies elevated compatibility or operational risk. Pure documentation, test-only, internal refactoring, and unreleased experimental changes may be marked no release, with a brief rationale.

For a release-bearing task:

  1. update version metadata and CHANGELOG.md in the pull request; for a significant feature release, include a ### Website highlight with one - Public headline: Public summary bullet (headline at most 90 characters, summary at most 230). Explain what a visitor can now do in plain language, retaining meaningful preview/synthetic/availability limits. Do not copy Git subjects, implementation details or marketing claims. The homepage pulls this reviewed copy automatically from CI-published release notes. Lead with the enduring capability or integration and its user benefit. Name demo scenarios as supporting examples, not as the product feature. Describe shipped scope precisely: do not imply general production support from a synthetic reference integration. Prefer clear capability names over narrow demo actions, technical identifiers, superlatives or vague novelty.
  2. run the release gates documented in docs/releasing.md;
  3. merge through the normal issue-to-merge process;
  4. create and push the matching version tag;
  5. verify that the release workflow publishes the GitHub release and artifacts.

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.
