chronos

chronos is a skill for Claude Code from bestdeejay-design/agent-skills. It costs 118 tokens per session (1,656 once invoked), scanned A, original, MIT.

A documentation audit system made of five focused checks for duplicates, broken links, missing required files, document classification, stale dates, and contract references.

In plain words
What is it for?
Use it to check a project's documentation tree, classify documents from L1 contracts through L6 auxiliary files, find missing or orphaned documents, and validate cross-references.
Why use it?
It brings several documentation-integrity checks into one audit instead of requiring separate manual reviews.

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

chronos 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 1mo ago.

The scan reads SKILL.md. This mod also ships 22 executable files (src/chronos/__init__.py, src/chronos/__main__.py, src/chronos/agents/__init__.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Chronos — Documentation Timekeeper

5 AI agents for documentation integrity. Each agent is a focused skill invoked by the Chronos orchestrator.

What it does

Chronos audits project documentation for:

  • Duplicates — documents with high similarity (Censor)
  • Broken links — references to non-existent files (Censor)
  • Missing required docs — mandatory files per classification level (Dewey)
  • Orphans — documents with no inbound references (Dewey)
  • Classification — document type: L1 Contracts → L6 Auxiliary (Dewey + Canon)
  • Stale data — dates older than threshold (Veles)

Agents

Agent Role Trigger
Chronos Orchestrator — runs the full Pantheon chronos --preset full
Censor Fact-checker — duplicates + broken links chronos --preset minimal
Dewey Classifier — L1-L6 taxonomy + missing/orphans chronos --preset standard
Veles Statistician — staleness, metrics, trends chronos --preset full
Canon Truth-keeper — cross-ref validation against contracts chronos --preset standard

Usage

# Basic audit (duplicates + links only)
chronos --path .

# Standard: check + classify (Censor + Dewey + Canon)
chronos --path . --preset standard

# Full Pantheon: all 5 agents
chronos --path . --preset full

# JSON output for CI
chronos --path . --output json --output-file report.json

# Fail on critical findings
chronos --path . --fail-on critical

# Single agent
chronos --path . --agent censor

Presets

Preset Agents Use case
minimal Censor Quick CI gate — duplicates + broken links
standard Censor + Dewey + Canon PR validation — check + classify + cross-ref
full All 5 agents Release audit — complete integrity + staleness

Document Hierarchy (L1–L6)

L1: Contracts        — Machine truth (OpenAPI, AsyncAPI, JSON Schema)
L2: Product Canon    — Human truth (VISION, PRD, ROADMAP, FEATURES)
L3: Engineering Canon— Implementation truth (ARCHITECTURE, ADR, SAGA)
L4: Derived          — Synthesized (REFERENCE, TEST_CASES, DEV_GUIDE)
L5: Artifacts        — Generated (API docs, changelogs, diagrams)
L6: Auxiliary        — Supporting (README, CONTRIBUTING, templates)

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.
