What is vibe-code CLAUDE.md?

A Claude Code instruction set for treating coding work as a measured experiment. It defines workflows, templates, data collectors, hooks, and records for predicting, carrying out, reviewing, and improving tasks.

Use it to assess tasks, record blind predictions, run retrospectives, track progress, score results, and update working rules.

It gives coding sessions a repeatable way to compare expectations with results and learn from past work. This reduces guesswork about how tasks are planned and reviewed.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01727	$0.01727
Opus 5.5	$0.00691	$0.00691
Sonnet 5.5	$0.00345	$0.00345

Security

Grade A, and why

vibe-code CLAUDE.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.

Origin

This is a copy

94% identical to vibe-code AGENTS.md — 13 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

CLAUDE.md — Vibe Code

What this is

vibe-code turns vibe coding into a calibrated experiment: assess task → blind prediction → execute → retro → evolve the rubric. It is a Claude Code skill collection (13 skills, 7 protocols, adapters, hooks, templates).

The SKILL.md at project root is the master router; each skills/vibe-*/SKILL.md is a sub-skill workflow.

Directory map

skills/vibe-{init,assess,retro,bump,status,score,score-blind,seed,recommend,trends,profile,learn-from,migrate}/SKILL.md
shared-references/    — 7 protocols (blind-prediction, bump-validation, observation-lifecycle, etc.)
templates/            — 7 templates (rubric, task, prediction, retro, benchmark, status, prompt-patterns)
adapters/             — data collectors (git-stats, time-tracker, lint-collector)
hooks/                — prediction-immutability.sh, session-start.sh, log-event.sh + JSON configs
tasks/                — user task descriptions
predictions/          — immutable blind prediction logs
retros/               — per-task retro data
tests/                — test scripts for adapters/hooks/tools
tools/                — accuracy-curve.py
migrations/           — schema migration registry
starter-rubrics/      — rubric presets per project type

Three non-negotiable principles

Blind prediction: Predictions written BEFORE coding, immutable once saved. Full spec: shared-references/blind-prediction-protocol.md.
Bump = full rescore: Changing the rubric formula requires rescoring all historical tasks. Ranking consistency >= 80% + cross-model audit. Spec: shared-references/bump-validation-protocol.md.
Rubric is a workbench, not a museum: Disproven observations get deleted, absorbed ones get deleted. Git history is the archive. Spec: shared-references/observation-lifecycle.md.

Core convention: one task, three files, one hash

tasks/<date>_<hash>_<short>.md       — task description
predictions/<date>_<hash>_<short>.md — blind prediction (immutable prediction section)
retros/<date>_<hash>_<short>/        — retro data

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.
