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.

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 | $0.00088 | $0.01324 |
| Opus 5 | $0.00044 | $0.00662 |
| Sonnet 5 | $0.00018 | $0.00265 |
| Haiku 4.5 | $0.00009 | $0.00132 |
Grade A, and why
research-phase 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 5d 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 — 194 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Research Phase
Map and document codebase structure using structural analysis. This skill produces factual maps only—no suggestions, no recommendations, no opinions. Document what exists, where it lives, and how it connects.
Core Principle
Map, don't suggest. The output is a structural map that another developer (or Claude instance) can use to navigate the codebase. Include:
- File paths with line numbers
- Pattern locations
- Dependency relationships
- Symbol definitions
Exclude:
- Improvement suggestions
- Refactoring recommendations
- "Should" or "could" statements
- Opinions about code quality
Available Scripts
scripts/ast-scan.sh - Structural Pattern Scanner
Find code patterns using ast-grep.
# Scan for all function definitions
scripts/ast-scan.sh functions src/
# Find all class definitions
scripts/ast-scan.sh classes
# Find all exports
scripts/ast-scan.sh exports lib/
# Find API routes
scripts/ast-scan.sh routes
# Available patterns: functions, classes, exports, imports, types, components, routes, handlers, all
scripts/structure-map.sh - Directory Tree
Generate filtered directory structure.
# Basic tree (auto-filters node_modules, .git, etc.)
scripts/structure-map.sh ./
# Limit depth
scripts/structure-map.sh ./ --depth 3
# Code files only
scripts/structure-map.sh src/ --code-only
# Include file counts
scripts/structure-map.sh ./ --with-stats
scripts/symbol-index.sh - Public Symbol Index
Extract all exported/public symbols.
# Index all exports
scripts/symbol-index.sh src/
# Shows: exported functions, classes, types, interfaces, constants
scripts/dependency-graph.sh - Import Tracer
Map dependency relationships.
# Show all imports
scripts/dependency-graph.sh src/
# Trace specific file's dependencies
scripts/dependency-graph.sh ./ --file src/core/auth.ts
# Shows: what it imports + what imports it

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

research-phase is a skill published in the GitHub repository alchemiststudiosDOTai/harness-engineering (104 stars, last pushed 5mo ago), licensed MIT. It adds 88 tokens to every session and 1,324 once invoked, about $0.0004 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 2026-08-30.
