session-indexer

session-indexer is a skill for Claude Code, Codex from Snowflake-Labs/cocoplus. It costs 33 tokens per session (310 once invoked), scanned A, a copy of audit-ci, MIT.

A deterministic contract for indexing sessions so an existing feature can find and use their stored information.

In plain words
What is it for?
It is for creating or updating session indexes and their structured artifacts.
Why use it?
It replaces an older script-based process and checks that the resulting index remains compatible with existing readers.

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

session-indexer 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 5d 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

95% identical to audit-ci — 4 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.

What it actually says

Your objective is to perform this V2-native feature behavior using Coco-native capabilities: Read, Write, Edit, Bash when explicitly needed by the host, Snowflake tools when the feature requires data access, and subagents when the feature requires independent review.

Required Contract

  • Preserve the artifact paths, schemas, and user-visible outputs documented by the owning feature skill.
  • Do not call legacy scripts as the implementation path.
  • Prefer deterministic file parsing and structured artifacts over free-form prose when producing machine-readable state.
  • If an external side effect would occur, apply the same gate and confirmation semantics as the owning feature.

Exit Criteria

  • The owning feature's documented artifact is produced or updated.
  • The output schema remains compatible with existing readers.
  • No registered runtime script invocation is required.

Anti-Rationalization

Shortcut / Temptation Why It Fails
Treat the skill as complete because the file exists Skill contracts must describe observable behavior and verification, not just command names.
Skip artifact and safety checks for a small command Small commands still mutate state or guide execution; preserve the same gates.
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.
