capture-knowledge

capture-knowledge is a skill for Claude Code from Curt-Park/autology. It costs 84 tokens per session (1,001 once invoked), scanned A, original, MIT.

A knowledge-capture skill that records project decisions, conventions, reusable patterns, concepts, and known issues as Markdown files in a docs folder.

In plain words
What is it for?
Saving decisions, documenting new components or rules, recording explained concepts, capturing reusable approaches, and noting technical debt or known problems.
Why use it?
It prevents useful decisions from being lost in chat and keeps verified project knowledge available for later work.

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

capture-knowledge 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 6d 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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Overview

Capture knowledge from conversation context into docs/ as markdown nodes. Save immediately — asking confirmation interrupts flow and discourages capture.

Precondition: if triage has not run this session, run /autology:triage-knowledge first.

What Capture Targets

Capture the items triage classified as new (→ capture):

  • Decisions made (technology choices, architectural choices)
  • Components created or modified
  • Conventions or patterns established
  • Concepts or domain knowledge explained
  • Issues or technical debt identified

When NOT to capture:

  • Session-specific context (current task, temporary state)
  • Incomplete or unverified information
  • Items triage classified as existing (→ sync, not capture)

Quick Reference

Type Signals
decision "chose", "decided", "selected", "adopted"
component "created", "built", "implemented", new service/module
convention "always", "never", "must", "should", "the rule is"
concept lifecycle, workflow, domain model, process
pattern reusable approach, strategy, pattern
issue bug, technical debt, bottleneck, known problem
session work session summary, "finished", "completed"

type = primary classification (what kind?); tags = cross-cutting topics (what about?).

Process

1. Receive Triage Output

Use triage's new items list as the capture scope:

New items from triage (→ capture):
- [item description] — no matching node
  Suggested relations: [[foo]], [[bar]] (shared tags: architecture)
- [item description] — no matching node
  Suggested relations: none

2. Decide node granularity

Not every triage item needs its own file. Before creating, ask: does this item have enough standalone substance to be useful on its own, or is it a detail of something larger?

  • Own node: has a distinct title, multiple meaningful sentences, likely to be linked or searched independently
  • Decisions always get their own node — even if brief. A decision is "chose X over Y because Z": the rationale makes it independently searchable and worth linking from other contexts. E.g., "chose JWT over session cookies because we need a stateless API" → type: decision node, not a footnote in the component doc.
  • Fold into parent: a pure behavior detail, edge case, or implementation consequence of another item in the same batch (e.g., "returns 401 on invalid token" is a consequence of the JWT middleware, not a choice made with rationale)

3 files 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.

capture-knowledge is a skill published in the GitHub repository Curt-Park/autology (24 stars, last pushed 6mo ago), licensed MIT. It adds 84 tokens to every session and 1,001 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
