vibe-decisions

vibe-decisions is a skill for Claude Code from AGoldian/claudenv. It costs 131 tokens per session (1,372 once invoked), scanned A, original, MIT.

A decision guide for non-trivial technical choices, such as selecting libraries, algorithms, data structures, or system designs.

In plain words
What is it for?
Presenting a short comparison with one or two alternatives, then either waiting for confirmation or recording the decision automatically when running in loop mode.
Why use it?
It makes important trade-offs visible and records the chosen approach instead of allowing a significant choice to remain unexplained.

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

vibe-decisions 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.

How it starts

The opening of the file, as written. The whole thing — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vibe decisions

Mode detection (FIRST step every time)

Check the system prompt for the marker Vibe-decisions mode (loop).

  • Marker present → AUTO-LOG mode. Pick the approach, write the decision file, continue. NEVER pause. NEVER ask "делать так?". This is claudenv loop and pause violates autonomy=law.
  • Marker absent → INTERACTIVE mode. Output brief overview, wait for user confirmation or /deeper.

Both modes share the same trigger criteria, file format, and slash-command behavior. Only output shape and pause behavior differ.

Trigger criteria

Trigger if the decision involves:

  • choosing a library or framework from 2+ viable options
  • choosing an algorithm or data structure with meaningful trade-offs
  • architecture pattern (sync/async, push/pull, where state lives, monolith/services)
  • correctness vs performance vs simplicity trade-off
  • anything where reasonable engineers would disagree

DO NOT trigger for:

  • syntax-level choices in a single language (for vs map, ternary vs if)
  • obvious choices (JSON for a config file, regex for simple pattern)
  • pure refactoring within established patterns
  • when the user typed /just-code in the previous turn

Step 1 — Check memory before deciding

Before writing brief or auto-log, read related precedents:

  • view /memories/decisions/ — list files; if any topic looks related, read it
  • Mention the precedent briefly: "Раньше для X выбирали Y (см. )"

Step 2A — AUTO-LOG mode output (inside claudenv loop)

Output exactly this shape in the user's language, then continue with code in the same turn:

**Выбрано:** <approach>
**Почему:** <one sentence>
**Альтернативы:** <A> — <terse trade-off>; <B> — <terse trade-off>
**Лог:** /memories/decisions/<YYYY-MM-DD>-<topic-slug>.md (scope: <global|project>)

Immediately after the block, use the Write tool to create the decision file (see Step 4 for format). Then proceed with the actual code. Do NOT pause.

Step 2B — INTERACTIVE mode output (no loop)

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.

vibe-decisions is a skill published in the GitHub repository AGoldian/claudenv (10 stars, last pushed 3mo ago), licensed MIT. It adds 131 tokens to every session and 1,372 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
