percolate-kb

percolate-kb is a skill for Codex from hraness/atet. It costs 70 tokens per session (1,154 once invoked), scanned A, a copy of percolate-kb, MIT.

A workflow for reviewing a Markdown knowledge vault, a folder of linked notes, and promoting well-supported ideas and relationships into its knowledge graph.

In plain words
What is it for?
Use it after changing notes or while organizing a vault to inspect recurring tags, concepts, backlinks, and possible relationships with the KB command-line tool.
Why use it?
It helps find repeated concepts and missing connections while keeping the original Markdown notes as the source of truth.

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

percolate-kb 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.

How it starts

The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Percolate concepts and relationships

Keep the graph authored, local, and reviewable. kb percolate proposes candidates from deterministic evidence; it never changes a note. Backlinks, graph reports, and QMD results are derived views, while Markdown remains the authority.

Locate the vault

  • Resolve <vault> to the directory containing its authored or managed index.md front door.
  • Read the applicable repository and vault instructions before editing.
  • Pass the resolved path to every --root.
  • Identify the note or small neighborhood changed by the current task. Prefer a bounded review to a vault-wide cleanup during parallel work.

Inspect candidates

Run percolation on the changed note when possible:

kb percolate notes/example --root "$KB_ROOT" --limit 25 --json

Run it without a note only when reviewing the whole vault:

kb percolate --root "$KB_ROOT" --min-support 2 --limit 50 --json

Treat each result as a prompt to open the cited notes and read the relevant prose. Candidate kinds may include:

  • a recurring tag with no maintained type: concept note;
  • notes that share a concept or tag but have no explicit relationship;
  • an exact title or alias mentioned without a contextual link;
  • a self, reciprocal, malformed, broken, or ambiguous authored relationship.

For missing relationships, support counts independent shared tags or concept neighbors; the evidence array shows the participating notes. The default minimum of two therefore requires two shared signals, not merely both endpoints of one tag match. Other candidate kinds count their natural unit: supporting notes, mention occurrences, or authored hygiene evidence.

For a missing concept, use suggestedId. When collidesWith is non-null, the natural ID is already an ordinary note, so KB chooses an unoccupied *-concept ID. Read the occupied note before deciding whether to create the suggested concept or promote and improve the existing note instead.

Semantic search may help discover evidence, but similarity is never enough to author an edge.

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.
