A skill for searching past conversations and reading profile and memory files managed by Dream. It covers both long-term notes and an append-only history log.

Finding relevant past events, checking saved user or project information, and using conversation history during a task.

It helps recover earlier decisions, events, and user preferences instead of relying only on the current conversation.

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.

Model	Per session	Once invoked
Fable 5	$0.00014	$0.00445
Opus 5	$0.00007	$0.00222
Sonnet 5	$0.00003	$0.00089
Haiku 4.5	$0.00001	$0.00044

Measured 4d ago against content hash 0946a34d4519, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

Security

Grade A, and why

memory 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 4d 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.

What it actually says

Memory

Structure

SOUL.md — Bot personality and communication style. Managed by Dream. Do NOT edit.
USER.md — User profile and preferences. Managed by Dream. Do NOT edit.
memory/MEMORY.md — Long-term facts (project context, important events). Managed by Dream. Do NOT edit.
memory/history.jsonl — append-only JSONL, not loaded into context. Prefer the built-in grep tool to search it.

Search Past Events

Use the History log path shown in the system prompt. Always pass it to grep; never substitute a different project-relative memory/history.jsonl, which may belong to the selected project. Each JSONL line contains cursor, timestamp, and content.

For broad searches, start with output_mode="count" or the default files_with_matches mode before expanding to full content
Use output_mode="content" plus context_before / context_after when you need the exact matching lines
Use fixed_strings=true for literal timestamps or JSON fragments
Use head_limit / offset to page through long histories

Examples (replace <history-log-path> with the path from the system prompt):

grep(pattern="keyword", path="<history-log-path>", case_insensitive=true)
grep(pattern="2026-04-02 10:00", path="<history-log-path>", fixed_strings=true)
grep(pattern="keyword", path="<history-log-path>", output_mode="count", case_insensitive=true)
grep(pattern="oauth|token", path="<history-log-path>", output_mode="content", case_insensitive=true)

Important

Do NOT edit SOUL.md, USER.md, or MEMORY.md. They are automatically managed by Dream.
If you notice outdated information, it will be corrected when Dream runs next.
Users can view Dream's activity with the /dream-log command.

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.
