vibetags AGENTS.md

vibetags AGENTS.md is an instructions file for Codex, OpenCode from PIsberg/vibetags. It costs 2,683 tokens per session, scanned A, original, MIT.

Project instructions for VibeTags, a tool that generates guidance files for AI coding assistants.

In plain words
What is it for?
Use them when modifying the VibeTags repository, especially when changing generated instructions, architecture, or its separate subprojects.
Why use it?
They explain which project rules to follow, which files are generated or locked, and the required build order, reducing accidental edits and broken builds.

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

vibetags 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

VibeTags — Agent Instructions

Start with llms.txt for a map of this repo's docs and layout.

The primary agent briefing is CLAUDE.md — build commands, build order, architecture invariants, and the <project_guardrails> block (locked files, contract-frozen signatures, hot-path constraints). It is tool-neutral despite the name: read and follow it whichever agent you are.

Ground rules for any agent working here:

  • Respect the guardrails in CLAUDE.md: never edit files/elements listed as locked, never change contract-frozen signatures.
  • Never hand-edit content between VIBETAGS-START/VIBETAGS-END markers in any file — it is generated by this project's own annotation processor.
  • Build order matters: vibetags-annotationsvibetagsvibetags-bomexample. Always build from the subproject's own directory.
  • Reference docs load on demand: docs/ANNOTATIONS.md (annotation reference), docs/PLATFORMS.md (output-file table), docs/TESTS.md (test coverage map), docs/ARCHITECTURE.md (deep dive), docs/DEPENDENCIES.md (third-party artifacts).

Note: this file is intentionally not VibeTags-managed — other AI config files exist at the root, so the processor's AGENTS.md sole-file fallback leaves it untouched.

AUTO-GENERATED AI RULES

Generated by VibeTags | https://github.com/PIsberg/vibetags

Do not edit manually.

LOCKED FILES (DO NOT EDIT)

  • se.deversity.vibetags.processor.AIGuardrailProcessor.generateFiles(): Step order is load-bearing: fingerprint check → sidecar write → sidecar read → merge → file write → cache flush; reordering steps silently skips regeneration or corrupts multi-module output
  • se.deversity.vibetags.processor.internal.TransitiveManifest.RESOURCE_PACKAGE: Must stay a valid Java package name. javac's CLASS_PATH location skips archive directories that are not package identifiers, so moving these manifests under META-INF/ leaves Filer.getResource listing zero entries and transitive discovery fails silently while the conventional location looks correct. TransitiveManifestPathTest pins the working path.
  • se.deversity.vibetags.processor.model.GuardrailAnnotations.ALL: Append only. This order fixes the insertion order of every LinkedHashSet downstream, so reordering or removing an entry rewrites generated files in every consuming build, with nothing failing to name the cause. BuildFingerprint hashes in its own separately pinned order; the two are not the same list and must not be aligned.

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.
