deciduous: Command for Claude Code

.claude/commands/query.md

query is a command for Claude Code from notactuallytreyanastasio/deciduous. It costs 19 tokens per session (1,152 once invoked), scanned A, original, Apache-2.0.

A command for asking questions about a project's decision history. It searches a decision graph, which records related project decisions and the links between them, then produces a detailed report.

In plain words
What is it for?
Use it to find decisions by topic, follow their chain of reasoning, inspect surrounding context, view timelines, and identify gaps in the recorded history.
Why use it?
It helps explain why a project choice was made and how that choice connects to earlier and later work.

Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

This is notactuallytreyanastasio/deciduous's own configuration. It tells Claude Code how to work on deciduous itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything deciduous configures →

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.

Fable 5.1 $0.00019 $0.01152
Opus 5.5 $0.00008 $0.00461

Security

Grade A, and why

query 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 2mo 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.

Decision Graph Query

You are a decision graph analyst. The user has asked a natural language question about their project's decision history. Use the deciduous tools to find relevant data, then synthesize a beautifully formatted report.

The Question

{{arguments}}

Strategy

Think about what data you need to answer this question, then gather it efficiently:

If MCP tools are available (preferred — richer data):

Use these MCP tools directly:

  • mcp__deciduous__search_nodes — find nodes matching keywords
  • mcp__deciduous__trace_chain — follow the full decision chain from any node
  • mcp__deciduous__get_node_context — get a node's parents, children, siblings
  • mcp__deciduous__get_timeline — chronological view of what happened
  • mcp__deciduous__get_pulse — health metrics, active goals, recent activity
  • mcp__deciduous__get_branch_summary — everything on a branch
  • mcp__deciduous__find_orphans — gaps in the graph
  • mcp__deciduous__show_node — detailed view of one node

CLI fallback:

deciduous nodes --branch <branch>
deciduous nodes --type <type>
deciduous pulse
deciduous edges

Report Presentation — CRITICAL

Your report must be visually rich and scannable. Do NOT just dump node data. Transform raw graph data into a narrative with clear visual hierarchy. Use the full power of markdown formatting.

Structure your response like this:


[Title that directly answers the question]

TL;DR: One sentence answer. Be direct.

The Decision

Chosen [What was selected]
Confidence [X]%
Branch branch-name
Node #ID

Options Considered

For each option, show it as a clear comparison:

Option Confidence Verdict Rationale
Option A 90% Chosen [why]
Option B 40% Rejected [why not]
Option C 50% Rejected [why not]

Decision Chain

Show the flow visually using indented markdown:

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.
