surveycto-agent-skill: Instructions file for Codex

AGENTS.md

surveycto-agent-skill AGENTS.md is an instructions file for Codex, OpenCode from surveycto/surveycto-agent-skill. It costs 3,355 tokens per session, scanned A, original, Apache-2.0.

Contributor instructions for a package that gives AI agents knowledge of SurveyCTO, a platform for creating and managing field data-collection surveys. It describes the repository, branches, versioning, releases, and local testing.

In plain words
What is it for?
Use it when developing, testing, versioning, or releasing the SurveyCTO agent skill.
Why use it?
It explains how changes become development or release packages and helps contributors avoid breaking the publishing process.

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

This is surveycto/surveycto-agent-skill's own configuration. It tells Codex and OpenCode how to work on surveycto-agent-skill itself, so it is not a mod to install elsewhere.

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

surveycto-agent-skill 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.

Working on this repo

This file orients an AI agent (or a human) making changes to the SurveyCTO Agent Skill itself. It is not part of the skill bundle — it is excluded from surveycto-skill.zip / surveycto-skill-dev.zip.

For end-user-facing documentation see README.md. For the skill content itself see SKILL.md.

What this repo is

An Agent Skills package that gives AI agents SurveyCTO domain expertise. The deliverable is a zip (surveycto-skill.zip) that hosts (Claude Cowork, Codex, etc.) extract into their skills directory. The zip is not committed — it's built and published by GitHub Actions:

  • Push to develop.github/workflows/build-dev.yml builds surveycto-skill-dev.zip as a workflow artifact (downloadable from the run page) for smoke-testing pre-release changes.
  • Push to main.github/workflows/release.yml builds surveycto-skill.zip and attaches it to a new GitHub Release whose tag/name comes from metadata.version in SKILL.md.

For local smoke-testing, you can build a zip yourself (see When to rebuild the local zip). It stays in your working tree and is gitignored.

Branching

  • develop — active development. Pushes here trigger the dev-build workflow.
  • main — stable releases. Pushes here trigger the release workflow.

Default working branch for new work is develop (or a feature branch off develop). PRs target develop first; develop → main is reserved for release.

When to bump the version

The release workflow takes its tag from metadata.version in SKILL.md. If develop is merged into main without a bump since the last release, the workflow will try to re-tag the same version and the release will fail (or, worse, silently overwrite, depending on settings).

Procedure before making non-trivial changes to skill content (SKILL.md, references/, assets/):

  1. Compare the current branch's metadata.version in SKILL.md against main's:
    git show origin/main:SKILL.md | sed -n '/^metadata:/,/^---/p' | grep version
    
  2. If the two match, the current branch hasn't been bumped since the last release — bump it as part of this change. If they already differ (current is ahead of main), no further bump is needed unless the new change crosses a different semver boundary than the bump that's already there.
  3. If you're unsure (e.g. the change is small, or the user hasn't asked), ask or offer rather than skipping. A missed bump blocks release; an unnecessary bump is harmless.
  4. When bumping, update both places the version appears in SKILL.md (see below). They must stay in sync — the frontmatter drives the release tag and the body line is what the agent reports at runtime, since agents don't see frontmatter.

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.
