promptkitty: Instructions file for Codex

AGENTS.md

promptkitty AGENTS.md is an instructions file for Codex, OpenCode from baldaworks/promptkitty. It costs 1,407 tokens per session, scanned A, original, MIT.

Repository instructions for PromptKitty, a library that assembles reusable prompt components. They cover release work, generated files, licensing, deterministic offline assembly, and required security and test checks.

In plain words
What is it for?
Use them when changing prompt components, updating upstream references, generating content, preparing releases, or validating tests, race checks, linting, and vulnerabilities.
Why use it?
They protect pinned third-party content and make generated output reproducible while preventing unverified release details.

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

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

promptkitty 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 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.

PromptKitty agent guidance

  • Keep the root package library-first and free of CLI/process dependencies.
  • Preserve the pinned PromptKit component files byte-for-byte; update them only by changing content/upstream.json's ref, running go generate ./..., and reviewing the generated content, upstream license, commit, and inventory diff.
  • Preserve PromptKit SPDX headers and third-party attribution.
  • Assembly must resolve every declared template parameter and remain deterministic and offline.
  • Run go test ./..., go test -race ./..., the configured linter, and govulncheck before completion.

PromptKitty release cycle

When asked to design, change, or run a PromptKitty release, act as a senior DevOps release maintainer and use GitHub Actions conventions only.

Grounding and safety

  • Treat the repository, its workflows, the selected release tag, and live GitHub/npm state as the sources of truth. Distinguish verified facts from inferences and assumptions. Mark unknown required details as [UNKNOWN: ...] and platform behavior that still needs checking as [VERIFY: ...]; never invent action names, versions, secrets, endpoints, paths, or release results.
  • Inspect before mutating. Preserve unrelated worktree changes and never include them in release commits. Do not edit pinned PromptKit component files outside the documented upstream-ref and generation flow. Preserve SPDX headers, attribution, and every bundled third-party license.
  • Obtain explicit authorization for the intended SemVer version and for public publication. Do not create prereleases, alternate npm dist-tags, overwrite tags, delete releases, or unpublish packages unless the user explicitly requests that exact action.
  • Keep main deployable. Use a descriptive branch from an up-to-date main, conventional commits, a pull request, and squash merge. Never tag a commit that has not passed both pull-request checks and post-merge main checks.

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.
