Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 5.1 | $0.00093 | $0.01940 |
| Opus 5.5 | $0.00037 | $0.00776 |
| Sonnet 5.5 | $0.00019 | $0.00388 |
| Haiku 4.5 | $0.00009 | $0.00194 |
Grade A, and why
external-pattern-integrator 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 261 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Invocation Input
Read the source references supplied by the active harness. Parse one or more URLs or readable local paths. If none are supplied, or an unsubstituted argument placeholder is supplied, ask for at least one source before creating scratch output, fetching, editing, or creating a durable backlog item.
Workflow Overview
Phase 1: Parallel Candidate Mapping
├── For each external source (concurrent):
│ ├── Fetch/read the external file
│ ├── Analyze its purpose and patterns
│ └── Scan local files for candidates (frontmatter only)
└── Output: Tracking document with source → candidates mapping
Phase 2: Contextual Enhancement (concurrent per source)
├── Understand local file's workflow context FIRST
├── Compare against external patterns
├── Identify enhancements that fit the workflow stage
├── Add external artifact recognition for interoperability
└── Edit files with coordinated changes
Phase 3: Validation
└── Run linting on all modified files
Phase 1: Parallel Candidate Mapping
Step 1.1: Create Scratch Tracking Document
Create a task-local tracking document at .tmp/scratch/analysis/external-pattern-integration-{date}.md. It is an intermediate analysis record, not a durable backlog item:
# External Pattern Integration
**Date**: {YYYY-MM-DD}
**Sources**: {list of URLs/files from arguments}
**Status**: IN_PROGRESS
## Source Analysis
### Source 1: {URL or path}
**Purpose**: {What this external agent/skill does}
**Key Patterns**:
- {Pattern 1}
- {Pattern 2}
**Local Candidates** (by frontmatter similarity):
| Local File | Similarity Reason | Priority |
|------------|-------------------|----------|
| {path} | {why it matches} | {High/Medium/Low} |
### Source 2: {URL or path}
...
Step 1.2: Fetch External Sources
For each supplied URL or local path:
If URL: Fetch through the available documentation or web-reading capability and save only transient extracts under .tmp/scratch/ when a file is needed.
If local file: Read directly.
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.

external-pattern-integrator is a skill published in the GitHub repository Jamie-BitFlight/claude_skills (67 stars, last pushed 4d ago), licensed MIT. It adds 93 tokens to every session and 1,940 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-30.
