Cover: Test Suite Generator

Host-neutral workflow. Invoke by skill name (cover). Claude Code slash routing, YAML hook loaders, and .claude/chain live in skills/cover/references/claude-code.md.

Generate comprehensive test suites for existing code with real-service integration testing and automated failure healing.

Note: If disableSkillShellExecution is enabled (CC 2.1.91), the precondition check for vitest/jest won't run. Verify a test runner is installed before proceeding: npx vitest --version or npx jest --version.

Quick Start

cover authentication flow
cover --model=opus payment processing
cover --tier=unit,integration user service
cover --real-services checkout pipeline

Argument Resolution

A pronoun target (this, them, the above) is read back from the conversation, announced in one line, and used: Read("../../shared/rules/target-resolution.md"), inline half.

SCOPE = "$ARGUMENTS"  # e.g., "authentication flow"

# Flag parsing
MODEL_OVERRIDE = None
TIERS = ["unit", "integration", "e2e"]  # default: all three
REAL_SERVICES = False

for token in "$ARGUMENTS".split():
    if token.startswith("--model="):
        MODEL_OVERRIDE = token.split("=", 1)[1]
        SCOPE = SCOPE.replace(token, "").strip()
    elif token.startswith("--tier="):
        TIERS = token.split("=", 1)[1].split(",")
        SCOPE = SCOPE.replace(token, "").strip()
    elif token == "--real-services":
        REAL_SERVICES = True
        SCOPE = SCOPE.replace(token, "").strip()

Step -0.5: Effort-Aware Coverage Scaling (CC 2.1.76, env var since 2.1.120)

Read $CLAUDE_EFFORT (CC 2.1.120+) first; explicit --effort= token wins as override. Default high when CC < 2.1.120 and no flag. Pattern matches assess + explore (#1540). Scale test generation depth:

Effort Level	Tiers Generated	Agents	maxIterations to pass Phase 5
low	Unit only	1 agent	2 (1 repair + 1 verify)
medium	Unit + Integration	2 agents	2 (1 repair + 1 verify)
high (default)	Unit + Integration + E2E	3 agents	3 (2 repairs + 1 verify)
xhigh (CC 2.1.111+)	Unit + Integration + E2E	3 agents	3 (the ceiling; xhigh adds agents, not heal passes)
