index

index is a skill for Claude Code, Codex from sp-daewoon/chronicle. It costs 60 tokens per session (205 once invoked), scanned A, original, MIT.

A project home page in Markdown or HTML that links to important records such as architecture decisions, the changelog, and releases. An ADR is a written record of an important technical decision.

In plain words
What is it for?
Use it to generate or refresh a navigation page, choose which documentation sources to include, and keep links current after decisions, releases, or documentation changes.
Why use it?
It gives developers one place to find scattered project history and documentation, instead of searching through separate files.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

npx agentmods add skills/sp-daewoon/chronicle/index
Any agent
npx skills add sp-daewoon/chronicle --skill index
Clone the repo

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

index 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 4d 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.

What it actually says

Index Workflow

Generate a single entry-point index for the project.

Generate

node "${CLAUDE_PLUGIN_ROOT}/scripts/index-render.mjs"

This reads the configured index.sources (default: adr, changelog, releases), counts ADRs, checks for the changelog, and writes index.output. The format follows the output file extension — .md produces markdown, .html produces a self-contained page.

Rules

  • Re-run after adding ADRs, cutting releases, or restructuring docs.
  • Configure index.sources and index.output in chronicle.config.json to control scope and format.
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.
