talk-lamis-context-engineering-dreaming

talk-lamis-context-engineering-dreaming is a skill for Codex from jscraik/Agent-Skills. It costs 123 tokens per session (1,721 once invoked), scanned A, original, Apache-2.0.

A guide to Lamis’s AI Native DevCon talk about context engineering, which means deciding what information an AI agent receives and remembers. It covers memory tools, files used as memory, and “dreaming,” an asynchronous process that reviews past sessions for useful patterns.

In plain words
What is it for?
Use it to answer questions about agent memory, context files, Skills, filesystem-based memory, or the dreaming process, and to audit or design such systems using the talk’s source material.
Why use it?
It helps explain how agents can retain useful information across sessions without treating every past interaction as permanent memory. It also covers practical safeguards such as versioning, permissions, portability, and avoiding conflicting updates.

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

talk-lamis-context-engineering-dreaming 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.

Context Engineering, Memory Systems, and Dreaming — Lamis

A talk by Lamis (Anthropic, Applied AI team), introduced at AI Native DevCon by host Simon Maple (Tessl). Lamis walks through the past year's evolution of context engineering at Anthropic — from CLAUDE.md files to memory tools to Skills to filesystem-as-memory — and then introduces "dreaming": an out-of-band, asynchronous memory-curation process that reviews agent transcripts, spots cross-session patterns, and proposes changes to the memory store. The talk also covers the production guardrails (versioning, concurrency via hashing, permissioning, portability) needed to scale memory systems beyond a single agent and session.

Grounding rules — MUST follow when answering

  1. Before answering any specific question, read outline.md to locate the relevant section, then read that section of transcript.md.
  2. When attributing words, quote short, non-sensitive excerpts from transcript.md. Never put quotation marks around paraphrased content.
  3. If a claim isn't in transcript.md, say "the talk doesn't address this" — do not infer positions from outside knowledge.
  4. Cite by transcript line range whenever possible.
  5. Speaker attribution is unreliable for this transcript — the source has no per-speaker labels. The talk opens with what appears to be Simon Maple's welcome ("my name is Lamis" actually comes a few sentences in — note the introducer's voice transitions into Lamis's without a clear marker). Prefer phrasing like "the speaker said..." or "a questioner asked..." unless context makes attribution unambiguous. Do not invent attributions.
  6. Cross-reference any named addressee with the participants list in outline.md before attributing. The Q&A section contains audience questions whose askers are not named in the transcript — refer to them as "a questioner" or "an audience member".

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.
