Input Resolution and Docs Discovery

Covers Phase 0 of user-docs-to-ai-skill — resolving the source input to a local directory, deriving output_skill when not provided, and locating documentation within the resolved directory.

Source Type Resolution

flowchart TD
    Input([source input received]) --> Q{Starts with https://github.com/?}
    Q -->|Yes — GitHub URL| Clone["Run: git clone source .claude/worktrees/project-name/\nproject-name = last URL path segment"]
    Q -->|No — local path| UseLocal[Use source value as docs_root directly]
    Clone --> Cloned{Clone succeeded?}
    Cloned -->|Yes| SetRootClone[docs_root = .claude/worktrees/project-name/]
    Cloned -->|No — network or auth error| Block([BLOCKED — report clone failure with command output])
    UseLocal --> Exists{Directory exists?}
    Exists -->|Yes| SetRootLocal[docs_root = source]
    Exists -->|No| Block2([BLOCKED — report path not found])
    SetRootClone --> Done([docs_root resolved])
    SetRootLocal --> Done

Git Clone Command

git clone <source> .clone/worktrees/<project-name>/

• Path is relative to the project root — do not use absolute paths
• project-name is derived from the URL before cloning (see next section)
• If .clone/worktrees/<project-name>/ already exists, skip the clone and use the existing directory

Project Name Derivation

Extract project-name from the last non-empty path segment of the input.

Strip trailing slashes before extracting the segment.

output_skill Derivation

flowchart TD
    Q{output_skill provided by caller?}
    Q -->|Yes| Use[Use provided value as-is]
    Q -->|No| Derive[Derive from project-name]
    Derive --> Strip[Strip common suffixes: -tool, -sdk, -py, -python, -lib]
    Strip --> Lower[Lowercase, replace non-alphanumeric with hyphens]
    Lower --> Done([output_skill set])
    Use --> Done

Examples:

Docs Discovery

After docs_root is set, locate where the documentation lives.

flowchart TD
    Start([docs_root resolved]) --> Q1{docs_root/docs/ exists?}
    Q1 -->|Yes| UseDocs[docs_path = docs_root/docs/\nProceed to inventory]
    Q1 -->|No| Q2{docs_root/doc/ exists?}
    Q2 -->|Yes| UseDoc[docs_path = docs_root/doc/\nProceed to inventory]
    Q2 -->|No| Scan["Delegate to Explore subagent:\nGlob all *.md files under docs_root\nReturn list of file paths"]
    Scan --> Q3{Any .md files found?}
    Q3 -->|Yes — include README.md| UseList[docs_path = list of discovered .md files\nProceed to inventory treating each as a source file]
    Q3 -->|No markdown found| CheckRST["Glob *.rst files under docs_root"]
    CheckRST --> Q4{Any .rst files found?}
    Q4 -->|Yes| UseRST[docs_path = list of .rst files]
    Q4 -->|No| Block([BLOCKED — no documentation found in docs_root\nReport what was searched])
    UseDocs --> Inventory([Phase 0d — Inventory])
    UseDoc --> Inventory
    UseList --> Inventory
    UseRST --> Inventory

Explore Subagent Delegation

When no docs/ or doc/ directory exists, delegate discovery:

Task: subagent_type="general-purpose"
Prompt: Glob all *.md and *.rst files under <docs_root>.
        Also check for a README.md at docs_root root level.
        Return the full list of file paths found.
        Do not read file contents — paths only.
Output: flat list of file paths

Use general-purpose (not Explore) because the Explore agent has a ~50% hallucination rate on pattern-matching tasks.

Anti-Patterns

Using absolute paths in clone destination:

# WRONG
git clone https://github.com/astral-sh/ty /home/user/repos/.clone/worktrees/ty/

# CORRECT
git clone https://github.com/astral-sh/ty .clone/worktrees/ty/

Hardcoding docs_path before checking:

# WRONG — assumes docs/ always exists
docs_path = docs_root + "/docs/"

# CORRECT — check first, fall back to discovery

Fabricating output_skill from partial URL parsing:

# WRONG — astral-sh/ty parsed as "astral-sh"
project-name = first URL segment after github.com

# CORRECT — use the last segment
project-name = last URL path segment = "ty"
