Tcl — 128 Operations for AI Agents

Tcl runs the tooling behind chips and infrastructure: EDA flows, synthesis scripts, test automation. act101 exposes procs and namespaces as navigable structure, so agents work inside decades-old scripts with confidence.

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze Tcl code through the act MCP server. 128 operations available: 54 refactor, 18 query, 42 analysis, 14 verification. Each operation is callable from Claude Code, Cursor, Codex, OpenCode, or any MCP-compatible agent host. Click any operation for a stable anchor link suitable for citation.

Premium language. Operations on Tcl require an Elite license or above. See pricing.

Operation Description
add-comment Add a Tcl comment before a proc
add-default-parameter Add a default value to a Tcl proc parameter
add-error-handling Wrap a Tcl command in a catch error guard
add-namespace-export Add a Tcl proc to a namespace export command
add-package-provide Add a Tcl package provide declaration
add-parameter Add a Tcl proc parameter and update direct call sites
convert-class-to-procs Convert TclOO methods into standalone Tcl procs
convert-dict-to-switch Convert a simple Tcl dict get return to a switch mapping
convert-global-to-namespace Convert a Tcl global declaration to a namespace variable declaration
convert-namespace-to-global Convert a Tcl namespace variable declaration to a global declaration
convert-regexp-to-string-match Convert a simple Tcl regexp command to string match
convert-return-to-upvar Convert a simple Tcl return value to an upvar output assignment
convert-string-match-to-regexp Convert a simple Tcl string match glob to regexp
convert-switch-to-dict Convert a simple Tcl switch return mapping to dict get
convert-to-tcloo-class Convert namespace-style Tcl procs into a TclOO class
convert-upvar-to-return Convert a simple Tcl upvar output variable to a returned value
extract-namespace Extract selected Tcl procs into a new namespace
extract-proc Extract selected Tcl command lines into a new proc
extract-to-package Extract selected Tcl procs into a package namespace
extract-variable Extract a selected Tcl word or expression into a variable
extract_function Extract a code selection into a new function — automatically infers parameters, return types, and inserts the call site. Use instead of manually cutting/pasting code. Works without LSP; LSP improves type inference. Params: file (string), new_name (string), start_line (u32), start_column (u32), end_line (u32), end_column (u32) [, preview (bool), receipt (bool)]
extract_variable Extract an expression into a named variable — inserts the declaration and replaces the expression with the variable name. Works without LSP. Params: file (string), new_name (string), start_line (u32), start_column (u32), end_line (u32), end_column (u32) [, preview (bool)]
fix-eval-to-expansion Replace a simple Tcl eval command with {*} expansion
fix-incorrect-quoting Replace incorrect Tcl expression quotes with braces
fix-missing-braces Add missing braces to a Tcl expression or condition
fix-missing-namespace Qualify a bare Tcl command with a namespace path
fix-undefined-variable Add a Tcl global or namespace variable declaration
gen-arg-parser Generate Tcl command-line arg parser
gen-cgi-handler Generate Tcl CGI handler scaffold
gen-config-reader Generate Tcl config reader
gen-logging-procedure Generate Tcl logging procedure
gen-namespace-scaffold Generate a Tcl namespace scaffold
gen-proc-scaffold Generate a Tcl proc scaffold
gen-tcloo-class Generate a TclOO class scaffold
gen-test-procedure Generate a Tcl tcltest test scaffold
inline Inline a variable, function, or method — replace every usage with its definition body, then remove the original. The inverse of extract. Works without LSP (single-file); LSP enables cross-file inlining. Params: file (string), symbol (string) [, line (u32), preview (bool), receipt (bool)]
inline-namespace Inline a Tcl namespace into the top-level scope
inline-proc Inline a single-use no-argument Tcl proc at its direct call site
inline-variable Inline a single-use Tcl variable assignment
insert_body Replace a function's implementation body with new code. AST-validated — rejects if the result has parse errors, so you can't accidentally break syntax. Use instead of manual text editing for function rewrites. Params: file (string), symbol (string), code (string) [, commit (bool)]
modernize-syntax Modernize selected Tcl syntax
move_symbol Move a function, class, or type to a different file and automatically update all imports across the codebase. Use instead of manually cut/paste + fixing imports. Works without LSP (single-file); LSP enables cross-file import updates. Params: file (string), symbol (string), destination (string) [, preview (bool), receipt (bool)]
organize-imports Sort and deduplicate top-level Tcl package requirements
recipe_run Run a codemod recipe: declarative match → transform → optional verify across modeled grammars. Preview lists matches; apply writes with optional E7 receipts and all-or-nothing rollback. Returns a per-site report.
remove-default-parameter Remove a default value from a Tcl proc parameter
remove-error-handling Remove a simple Tcl catch error guard
remove-namespace-export Remove a Tcl proc from a namespace export command
remove-parameter Remove an unused Tcl proc parameter and matching direct call arguments
rename Rename a symbol and automatically update ALL references across the codebase. Safer and faster than find-and-replace — AST-aware, won't rename strings or comments. Works without LSP (single-file); LSP enables cross-file renames. Params: file (string), old_name (string), new_name (string) [, line (u32), column (u32), preview (bool), receipt (bool)]
rename-namespace Rename a Tcl namespace declaration and qualified same-file references
rename-proc Rename a Tcl proc declaration and direct command call sites
rename-variable Rename a Tcl variable in the selected proc or namespace scope
reorder-parameters Reorder Tcl proc parameters and matching direct call arguments
wrap-if Wrap selected Tcl command lines in an if block
