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

find-similar-posts 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/run.sh), 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.

What it actually says

Find Similar Posts

source_table='post'-filtered semantic search. Useful for "have I covered this already" questions before kicking off a new post, or for surfacing the related-reading list a fresh post should link to.

Backed by the same /api/memory/search route as search-memory, with source_table=post filter.

Usage

scripts/run.sh "<topic>" [limit]

Parameters

  • topic (string, required): natural-language description of what you're looking for
  • limit (int, optional, default 5): top-N posts to return

Output

One-line spoken summary: top hits with similarity, post-id slug, and a snippet.

Example

> scripts/run.sh "docker secrets management"
Found 4 matches. [0.78] post_91: 5 patterns for docker secret rotation in 2026... | [0.71] post_134: why every solo founder needs a secret manager...
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
