document-detection

document-detection is a skill for Claude Code, Codex from laurigates/claude-plugins. It costs 37 tokens per session (2,999 once invoked), scanned A, original, MIT.

A guide for recognizing when a conversation should become a structured document, such as a product requirements document, an architecture decision record, or an implementation plan.

In plain words
What is it for?
Use it while discussing features, technical trade-offs, or implementation scope to identify when a PRD, ADR, or PRP should be created.
Why use it?
It helps prevent important requirements, design decisions, and implementation details from being lost in chat.

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

document-detection 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 today.

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.

Document Detection

Proactively identify when conversations should become structured documents (PRDs, ADRs, or PRPs) and guide users through the documentation workflow.

When to Use This Skill

Use this skill when... Use blueprint-derive-plans instead when...
Mid-conversation cues suggest a PRD/ADR/PRP should be captured You're explicitly deriving plans (PRDs/ADRs/PRPs) from existing README/docs and git history
The user says "I want to build...", "users should be able to..." Use blueprint-derive-plans instead when the cue is a tech-choice decision worth an ADR
The user compares trade-offs ("should we use X or Y?") Use document-linking instead to wire IDs across already-created docs
Implementation scope is being discussed and warrants a PRP Use blueprint-prp-create instead when you've already decided to author a PRP

When This Skill Activates

This skill is loaded when conversation context suggests documentation opportunities:

  • Feature requirements being discussed
  • Architecture decisions being made
  • Implementation planning in progress
  • Technology trade-offs being evaluated

Prerequisites

Document detection requires:

  1. Blueprint initialized in project (docs/blueprint/manifest.json exists)
  2. has_document_detection: true in manifest structure
  3. docs/ directory structure created

Check prerequisites before prompting:

# Verify blueprint is initialized with document detection enabled
jq -r '.structure.has_document_detection // false' docs/blueprint/manifest.json 2>/dev/null

Detection Patterns

PRD Indicators (Product Requirements)

Primary triggers (confidence +0.5 each):

  • Feature descriptions: "I want to build...", "The system should...", "We need a feature that..."
  • User stories: "As a [user], I want...", "Users should be able to..."
  • Requirements enumeration: Lists of features or capabilities
  • Problem/solution framing: "The problem is... the solution is..."

Confidence boosters (+0.1-0.2 each):

  • Multiple features mentioned (+0.2)
  • User personas identified (+0.1)
  • Success criteria discussed (+0.1)
  • Priority levels mentioned (P0, P1, must-have, nice-to-have) (+0.1)
  • Timeline or milestones mentioned (+0.1)

document-detection is a skill published in the GitHub repository laurigates/claude-plugins (57 stars, last pushed yesterday), licensed MIT. It adds 37 tokens to every session and 2,999 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
