index-at-creation

index-at-creation is a skill for Claude Code from parcadei/Continuous-Claude-v3. It costs 9 tokens per session (186 once invoked), scanned A, original, MIT.

A guideline for indexing files and other artifacts as soon as they are created, so later steps can find them immediately.

In plain words
What is it for?
Use it when newly created handoffs or files must be searchable by downstream tools or workflows.
Why use it?
It prevents delays and missing data caused by waiting for a session to end or for a scheduled batch process.

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-at-creation 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 7d 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 at Creation Time

Index artifacts when they're created, not at batch boundaries.

Pattern

If downstream logic depends on artifacts being queryable, index immediately at write time.

DO

  • Index handoffs in PostToolUse Write hook (immediately after creation)
  • Use --file flag for fast single-file indexing
  • Trigger indexing from the same event that creates the artifact

DON'T

  • Wait for SessionEnd to batch-index
  • Rely on cron/scheduled jobs for time-sensitive data
  • Assume data will be available "soon enough"

Source Sessions

  • a541f08a: "Index at artifact creation time, not at SessionEnd"
  • 1c21e6c8: "If downstream logic depends on artifacts, index at the moment they're created"
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.
