基于 SOC 职业分类
Compare our compiler's bytecode output against tclsh reference disassembly (8.4, 8.5, 8.6, 9.0). Use when verifying bytecode correctness, investigating instruction sequence differences, or checking that our codegen matches C Tcl.
Debug the Tcl compiler pipeline (lexer → green tree → segmenter → IR → CFG → SSA → codegen) running from source — never a built pyz/zipapp. Wraps the tcl-explorer CLI and adds source-slice and raw-token views that make off-by-one range bugs obvious. Use when investigating a wrong diagnostic position, a stray-brace / unmatched-delimiter false positive, a mis-tokenised word, an IR statement whose range looks wrong, or any time you need to see what the compiler produces for a snippet of Tcl.
Manage differential-fuzzer findings: query fixed/unfixed status, list by category, verify findings against the current VM, mark findings as fixed/unfixed, and batch-update categories. Use when working on fuzz findings, checking what's fixed, or triaging new results.
Use when verifying Tcl LSP server behavior: semantic tokens, diagnostics, formatting, hover, completion, definition, references, code actions, optimizations, document symbols, diagram extraction, event/command registry lookups, or benchmarking server performance and collecting timing logs. Tests the server directly over JSON-RPC without VS Code.
Query reference test results captured from real tclsh (8.4–9.0). Look up individual tests, search groups, view suite summaries, and compare results across Tcl versions.
Run the full release workflow: validate branch, test, generate changelog, tag, push, and publish to all editor marketplaces. Asks for patch/minor/major if not specified. Tag-only — no source-file edits, no commit on main (main is protected).

Downloads Tcl release source tarballs from GitHub's codeload CDN
(https://codeload.github.com/tcltk/tcl/tar.gz/refs/tags/<tag>) and
extracts them to tmp/ so test suites, bytecode snippets, and reference
data are available without bundling Tcl source in the repository. Tarballs
are preferred over git clone because they are CDN-cached, smaller on
disk (no .git metadata), and easier on the upstream Tcl project.
bash .claude/skills/fetch-tcl-source/fetch_tcl_source.sh <version|all|status>
| Command | What it does |
|---|---|
84 or 8.4 | Fetch Tcl 8.4.20 source |
85 or 8.5 | Fetch Tcl 8.5.19 source |
86 or 8.6 | Fetch Tcl 8.6.16 source |
90 or 9.0 | Fetch Tcl 9.0.3 source |
all | Fetch all four versions |
status | Show which versions are present in tmp/ |
After fetching, the following directories are available:
| Directory | Key contents |
|---|---|
tmp/tcl8.4.20/tests/ | Tcl 8.4 test suite (for reference capture) |
tmp/tcl8.5.19/tests/ | Tcl 8.5 test suite |
tmp/tcl8.6.16/tests/ | Tcl 8.6 test suite |
tmp/tcl9.0.3/tests/ | Tcl 9.0 test suite (primary reference) |
Each source tree also contains generic/, library/, doc/, and build files.
