Asi substitute-eraser

This skill should be used when the user asks to "scan for TODOs", "find placeholders", "clean up stubs", "remove temporary code", "audit for incomplete code", or "erase substitutions from codebase". Scans existing files for placeholder tokens and generates remediation plan.

Substitute Eraser

Scan existing codebases for placeholder tokens. Generate remediation plan.

Purpose

Audit existing files for substitution tokens (TODO, FIXME, placeholder, mock, etc.) and produce actionable remediation plan. Distinct from 

accept-no-substitutes
which validates agent output.

Scope: Existing Files

This skill scans what already exists:

  • Source code files
  • Configuration files
  • Documentation with stale placeholders
  • Test fixtures that leaked into production

Complements 

accept-no-substitutes
(output validation).

Trit Assignment

  • Trit: -1 (MINUS/VALIDATOR)
  • Hue: 270° (violet - deep scan)
  • Role: Codebase auditor, technical debt detector

Scan Workflow

1. Discovery

# Scan current directory
just substitute-scan .

# Scan specific path
just substitute-scan src/

2. Classification

SeverityTokensAction
CRITICALTODO, FIXME, placeholder, xxxMust fix before merge
WARNINGmock-, fake-, stub-* (outside tests)Review context
INFOexample_, demo_Document or remove

3. Remediation Report

Output format:

SUBSTITUTE ERASER REPORT
========================
Scanned: 142 files
Found: 23 substitutions

CRITICAL (7):
  src/auth.py:42      TODO: implement token refresh
  src/api.py:118      placeholder value
  src/db.py:55        FIXME: race condition
  ...

WARNING (12):
  src/service.py:30   mock_client (not in test file)
  ...

INFO (4):
  README.md:15        example_config
  ...

REMEDIATION PLAN:
1. [CRITICAL] src/auth.py:42 - Implement token refresh logic
2. [CRITICAL] src/api.py:118 - Replace placeholder with actual value

Exception Syntax

Mark intentional placeholders:

# SUBSTITUTE-OK: mock used for test isolation
mock_client = MockHTTPClient()

Commands

# Full scan with report
just substitute-scan <path>

# Critical only (CI mode)
just substitute-critical <path>

# Generate remediation tasks
just substitute-tasks <path> --output=github  # GitHub issues
just substitute-tasks <path> --output=linear  # Linear tickets
just substitute-tasks <path> --output=todo    # TODO file

# Interactive fix mode
just substitute-fix <path>

Integration with GF(3)

Operates as MINUS (-1) in audit triads:

substitute-eraser(-1) + code-generator(+1) + review-coordinator(0) = 0

Emits rejection signal when scan finds violations above threshold.
