Caliber is a tool that generates and continuously updates AI context and configuration files for software repositories, including CLAUDE.md, AGENTS.md, and platform-specific rules. Development teams use it to keep coding agents aligned with the current codebase across tools such as Claude Code, Cursor, Codex, OpenCode, and GitHub Copilot. Its catalogue entries include skills, hooks, rules, instructions, and settings for configuring that workflow.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00095 | $0.03051 |
| Opus 5 | $0.00048 | $0.01525 |
| Sonnet 5 | $0.00019 | $0.00610 |
| Haiku 4.5 | $0.00010 | $0.00305 |
Grade A, and why
scoring-checks scanned grade A with 1 finding 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.
Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.
**Fix**: Scoring MUST be deterministic and offline. Use only: `fs` module (readFileSync, existsSync, readdirSync), `path`, `execSync` for git commands. No HTTP, no LLM calls, no external services. How it starts
The opening of the file, as written. The whole thing — 280 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Adding a Scoring Check
Add a new deterministic check that evaluates a single aspect of AI agent config quality. All checks must be filesystem-based with no network calls or LLM inference.
Critical
- Check must be deterministic: Same filesystem state → same result every time. No randomness, no external APIs.
- Point values come from constants.ts: Every
earnedPointsandmaxPointsmust referencePOINTS_*fromsrc/scoring/constants.ts. Do NOT hardcode numbers. - Always return
Check[]array: Export a functioncheck<Category>(dir: string): Check[]where category is one of:existence,quality,grounding,accuracy,freshness,bonus. - Every check must have:
id(kebab-case, unique),name,category,maxPoints,earnedPoints,passed,detail, and optionalsuggestion/fix. - Fix object fields:
action(string describing what to do),data(context for the fix),instruction(user-facing guidance). - Register in src/scoring/index.ts: Add the import and spread the result into the
allChecksarray incomputeLocalScore(). - Target filtering: If the check is platform-specific (Claude-only, Cursor-only, etc.), add its ID to the appropriate
*_ONLY_CHECKSset inconstants.ts.
Instructions
Step 1: Define point constants in src/scoring/constants.ts
Verify before proceeding: Is your check measurable with a numeric point value?
Add constants below the appropriate category section (existence, quality, grounding, accuracy, freshness, bonus):
// In the appropriate CATEGORY section, e.g., Quality checks (25 pts):
export const POINTS_YOUR_CHECK_NAME = 4; // 1-12 pts typical
// If threshold-based, add a companion array:
export const YOUR_THRESHOLD_ARRAY = [
{ minValue: 10, points: 4 },
{ minValue: 5, points: 2 },
] as const;
Check existing patterns: Token budgets use TOKEN_BUDGET_THRESHOLDS, code blocks use CODE_BLOCK_THRESHOLDS, concreteness uses CONCRETENESS_THRESHOLDS.
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.

scoring-checks is a skill published in the GitHub repository caliber-ai-org/ai-setup (1,263 stars, last pushed 1mo ago), licensed MIT. It adds 95 tokens to every session and 3,051 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
