Slash Commands
Create and use Claude Code slash commands with bash execution and file references
What You Can Do
You can create reusable slash commands that execute instantly in Claude Code conversations. Commands support bash execution, file references, arguments, and tool permissions. Use built-in commands like /cost, /review, /memory, and /clear, or define custom project and personal commands stored in .claude/commands/ or ~/.claude/commands/.
Features
`/cost`, `/clear`, `/compact`, `/config`, `/agents`, `/mcp`, `/memory`, `/model`, `/review`, `/resume`, `/help`
Store reusable prompts in `.claude/commands/` for team access and version control
Create user-specific commands in `~/.claude/commands/` for individual workflows
Prefix instructions with `!` to run shell commands and inject output into prompts
Specify which tools (Bash, Read, Write) each command can access via `allowed-tools`
Accept user input with `$1`, `$2`, or `$ARGUMENTS` placeholders and display hints
Define description, tool access, and argument format in command metadata
Embed file content and paths directly in command prompts
Example Output
Example 1: Built-in /cost command
Tokens used in this session: 45,230
Input tokens: 32,100 | Output tokens: 13,130
Estimated cost: $0.87
Example 2: Custom /optimize command output
Performance Analysis:
✓ Identified O(n²) loop in data processing (lines 45-52)
✓ Missing memoization on recursive function
✓ Suggests caching layer for repeated queries
Recommended fix: Implement request deduplication
Example 3: Bash-enabled /git-status command

You can rapidly process multiple subcontractor bid responses—from trade contractors, material suppliers, and specialty vendors—into a cohesive, auditable estimate structure. Claude extracts key bid components, identifies pricing inconsistencies against benchmarks or prior projects, flags scope gaps and exclusions, and organizes everything by CSI division for seamless estimate assembly. This eliminates manual spreadsheet comparison and reduces the risk of overlooked scope omissions or pricing anomalies when managing 15+ concurrent bids.

You can construct geometric objects (points, lines, polygons, multigeometries), execute boolean operations (intersection, union, difference), apply spatial predicates (contains, intersects, within), calculate measurements (area, length, distance, centroid), and transform geometries through translation, rotation, and scaling. This skill handles geometry validation, invalid geometry repair, and complex spatial analysis tasks.

You can systematically analyze construction estimates by breaking down components, validating labor and material pricing against market data, identifying embedded errors or outdated assumptions, and applying data-driven contingency allocation. Claude helps you produce risk-adjusted cost projections that are defensible to stakeholders and competitive in bid scenarios, reducing estimate variance and catching pricing gaps before client submission.

You can transform fragmented cost data, subcontractor quotes, and contingency calculations into cohesive, defensible bid packages that stakeholders understand and trust. This skill guides you through hierarchical cost aggregation, dynamic contingency modeling based on project risk, multi-tier markup application, and narrative integration that links scope assumptions to pricing—enabling you to develop competitive proposals with justified pricing strategies.

You can paste CPM schedule exports from Primavera P6, Microsoft Project, or narrative descriptions into Claude to perform comprehensive constraint analysis and identify schedule optimization opportunities. The skill analyzes activity relationships, float distributions, resource constraints, and schedule vulnerability patterns to quantify which activities drive project completion, measure schedule buffer effectiveness, and develop quantified mitigation strategies that balance acceleration with cost and logistical feasibility.

You can create, list, enable, disable, and run markdown-based AI automation pipes that execute on schedules ranging from every 30 minutes to custom cron expressions. Manage service connections to Telegram, Slack, Discord, and other platforms directly from the CLI, and troubleshoot pipe execution with built-in logging and debugging commands.

Solve algebraic and transcendental equations, compute derivatives and integrals, perform matrix operations, simplify expressions, compute limits and series expansions, solve differential equations, and convert units. Claude automatically selects the best computational engine for your problem—SymPy for symbolic math, Z3 for logical proofs, Pint for unit conversion—so you get fast, verified answers without manual tool selection.

You can deploy this agent to execute specific implementation tasks within a larger development plan. It operates independently with fresh context, follows test-driven development principles for every code change, and creates comprehensive handoff documentation that captures progress, decisions, and learnings for the next task executor. This ensures consistent code quality, prevents rework, and maintains continuity across distributed implementation efforts.
