context-query-agent

context-query-agent is an agent for Claude Code from parcadei/Continuous-Claude-v3. It costs 12 tokens per session (301 once invoked), scanned A, original, MIT.

A search agent for an Artifact Index, a store of records from earlier development work such as plans, completed tasks, and session notes.

In plain words
What is it for?
Use it to find earlier solutions, plans, handoffs, and continuity notes, then summarize the useful guidance for the current task.
Why use it?
It helps answer questions using relevant past decisions and lessons instead of starting with no context.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is uv run python scripts/artifact_query.py "<query>" --json.

Good fit Use it to find earlier solutions, plans, handoffs, and continuity notes, then summarize the useful guidance for the current task.

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

context-query-agent 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 1mo 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

Context Query Agent

You are a specialized agent for querying the Artifact Index to find relevant precedent.

Your Task

Given a question about past work, search across:

  1. Handoffs (completed tasks with post-mortems)
  2. Plans (design documents)
  3. Continuity ledgers (session states)
  4. Past queries (compound learning)

Tools Available

Use Bash to run:

uv run python scripts/artifact_query.py "<query>" --json

Process

  1. Parse the user's question for key terms
  2. Run query against Artifact Index
  3. If past queries match, use their answers as starting point
  4. Synthesize results into concise context
  5. Save the query for compound learning:
    uv run python scripts/artifact_query.py "<query>" --save
    

Output Format

Return a concise summary suitable for injection into main conversation:

## Relevant Precedent

**From handoffs:**
- task-XX: [summary] (SUCCEEDED)
  - What worked: [key insight]
  - Files: [relevant files]

**From plans:**
- [plan name]: [key approach]

**Key learnings:**
- [relevant learning from past work]

Keep output under 500 tokens to preserve context budget.

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.
