contextual-chunk-enrichment

contextual-chunk-enrichment is a skill for Claude Code, Codex from AllanWessels/Bratan. It costs 79 tokens per session (759 once invoked), scanned A, original, no licence file.

A text-enrichment technique for document chunks, which are smaller sections used by search systems. It adds a generated context block before each chunk is embedded, so unclear words such as “it” have more surrounding meaning.

In plain words
What is it for?
It is for improving retrieval from documents when chunks contain ambiguous references or depend on information from earlier text.
Why use it?
Short chunks can lose the subject they refer to, causing search to retrieve the wrong information. Adding context helps place each chunk in the right subject area.

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

contextual-chunk-enrichment 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 11d 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 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.
