knowledge-curator

A method for turning useful lessons from past coding sessions into lasting project documentation. It helps decide which temporary notes should become instructions, contributing guidelines, or reference material.

In plain words
What is it for?
Promoting repeated lessons, stable workarounds, migration outcomes, and repository-specific practices into documents that future sessions can use.
Why use it?
Important warnings and decisions can otherwise remain trapped in old conversations or be forgotten. It also helps remove stale or contradictory guidance.

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

knowledge-curator 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 2d 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.

Knowledge Curator

Not every useful insight belongs in a one-off chat. Knowledge Curator turns repeated lessons from session history into maintainable project guidance so future sessions start from better defaults.

Why This is Copilot-Exclusive

Copilot CLI gives you three building blocks that work well together:

  • Session artifacts for saving structured notes during a task
  • /resume for continuing a past session with its artifacts and SQL state
  • session_store search for finding prior discussions and patterns later

The key constraint matters: session_store is read-only historical memory, not a writable knowledge base. This skill is about deciding what should graduate from temporary session context into durable project docs such as .github/copilot-instructions.md, CONTRIBUTING.md, or reference guides.

When to Use

  • The same repo-specific warning or pattern keeps appearing across sessions
  • A temporary workaround has become a stable team practice
  • You want to prune stale guidance instead of accumulating contradictory notes
  • A sprint or migration produced lessons worth promoting into project instructions

When NOT to Use

Instead of knowledge-curator Use
You only need to find something from a past session copilot-exclusive/cross-session-memory
You need a first-pass backlog from external ecosystem research copilot-exclusive/ecosystem-intake
You are documenting a single hard-to-reverse technical decision documentation/architecture-decisions

Prerequisites

  • A candidate insight worth keeping
  • A target destination for that insight
  • Enough evidence to tell whether it is stable, repeated, or obsolete

Knowledge Layers

Layer Medium Best for
Session session artifacts, SQL notes, current plan In-progress findings, experiments, temporary context
Historical session_store search + /resume Looking up what happened in earlier sessions
Durable .github/copilot-instructions.md, CONTRIBUTING.md, reference docs Stable project rules, patterns, and team-facing guidance

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.

knowledge-curator is a skill published in the GitHub repository drvoss/everything-copilot-cli (45 stars, last pushed 5d ago), licensed MIT. It adds 38 tokens to every session and 1,263 once invoked, about $0.0002 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.
