At a glance

Search past Claude Code session logs to recall prior decisions, patterns, or unresolved work.

  • Works in 2 steps: Query → Internalize
  • User says do you remember
  • SKILL.md covers Step 1 — Query and Step 2 — Internalize
  • Calls duckdb

What it does

Read Memories is an agent skill from duckdb/duckdb-skills, published by the product's own GitHub organization. Search past Claude Code session logs to recall prior decisions, patterns, or unresolved work. Use when user says "do you remember", "what did we do", references past conversations, or you need context from prior sessions.

Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The licence is MIT.

When your agent uses it

  • User says do you remember
  • References past conversations
  • You need context from prior sessions

Example prompts

  • “do you remember”
  • “what did we do”
  • “/read-memories”

Requirements

  • Pre-approved tools (allowed-tools): Bash

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. Query
  2. Internalize

What it can do on your machine

Read from SKILL.md and the folder at commit 7feda8e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • duckdb

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Read Memories loads about 346 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 83 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~346

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

argument-hint
<keyword> [--here]

Search past session logs silently — do NOT narrate the process. Absorb the results and continue with enriched context.

$0 is the keyword. Pass --here as $1 to scope to the current project only.

Step 1 — Query

bash
duckdb :memory: -c "
SELECT
  regexp_extract(filename, 'projects/([^/]+)/', 1) AS project,
  strftime(timestamp::TIMESTAMPTZ, '%Y-%m-%d %H:%M') AS ts,
  message.role AS role,
  left(message.content::VARCHAR, 500) AS content
FROM read_ndjson('<SEARCH_PATH>', auto_detect=true, ignore_errors=true, filename=true)
WHERE message::VARCHAR ILIKE '%<KEYWORD>%'
  AND message.role IS NOT NULL
ORDER BY timestamp
LIMIT 40;
"

Search paths:

  • All projects: $HOME/.claude/projects/*/*.jsonl
  • Current only (--here): $HOME/.claude/projects/$(echo "$PWD" | sed 's|[/_]|-|g')/*.jsonl

Replace <SEARCH_PATH> and <KEYWORD> before running.

Step 2 — Internalize

From the results, extract decisions, patterns, unresolved TODOs, and user corrections. Use this to inform your current response — do not repeat raw logs to the user.
