Julian Noble	75cffe21f3	punk::args 0.12.6 + punk::ns 0.9.0: LLM-oriented usage output; tcl-whatis agent skill ... punk::ns 0.9.0: cmdhelp (i) gains -return text - plain-text argument documentation for machine/LLM consumption: no ANSI, no table layout, the argument section of every command form rendered in one output under a common header ('i -return text after' shows all six forms), G-041 form selection still honoured when argument words are supplied, no advisory-parse error preamble (-return dict remains the parse-status surface). Implementation delegates resolution to the -return dict recursion and renders per-form via the string renderer. punk::args 0.12.6 (user direction; string-form layout explicitly not frozen - no external consumers yet): - arg_error renders the error message + per-form match detail exactly once, BELOW the usage display (was above and below); bottom append suppressed for empty messages. - string renderer argument rows are single-line 'name TYPE:type(constraints) ?DEFAULT:'val'? ?MULTI:yes?' - type constraints parenthesize onto the base type instead of line-breaking mid-row; empty DEFAULT/MULTI labels and whitespace-only help blocks omitted. - choices render as markdown-subset bullets '- `choice` - label' with label continuations at a fixed deeper indent - choice names are now machine-distinguishable from label text without ANSI. Structural contract: column-0 lines bearing TYPE: are argument rows, indented lines are documentation, backticked bullets are choices. Table cells unchanged. New scriptlib/developer/whatis.tcl (runtime command introspection for agents): resolved name, subcommand-chain resolution via punk::ns::cmdinfo ('whatis string is'), kind, providing package + loaded version, origin file, proc definition file:line, punk::args synopsis; -body appends the runtime body with file-relative line numbers, -doc the full plain-text argdoc via cmdhelp -return text (with fallback for older punk::ns). Backing the cross-framework tcl-whatis agent skill: canonical .agents/skills/tcl-whatis/ (Agent Skills standard - pi/OpenCode/Codex) with byte-identical copy in .claude/skills/ for Claude Code; .gitignore gains !.claude/skills/ with the fossil ignore-glob comment + exception-set docs updated per the dual-VCS contract (fossil adds staged). Root AGENTS.md: .agents/skills index entry, whatis pointer in Repo-wide Notes, scriptlib/developer example. Tests: new pins cmdhelp_return_text_all_forms/_argword_form_selection/ _single_form_plain_marker (cmdhelp.test), rendering_stringmode_singleline_argrows + rendering_stringmode_choice_bullets (rendering.test); deliberate-change pin updates: errorselection.test message matches gained leading * and cmdhelp.test message pins sample the last line (message placement). Full source-tree suite 963/979 pass, sole failure the pre-existing exec-14.3 baseline; make.tcl modules clean. Project version 0.12.42 -> 0.13.0 with CHANGELOG.md entry.

Julian Noble	06db38be46	agent guardrails: tclsh has no -e one-liner flag - AGENTS.md pitfall entry + claude PreToolUse deny hook ... Stock tclsh treats any leading-dash arg other than -encoding as argv for an interactive/stdin session: on a console it hangs at a prompt, with piped stdin it exits 0 silently ignoring the supposed one-liner. Agents habitually reach for -e (perl/python/node reflex), wasting time waiting on hung processes. - root AGENTS.md User Preferences: document the misparse, the correct patterns (temp .tcl file or script via stdin) and the defensive stdin-redirect habit - .claude/settings.json: PreToolUse hook denying Bash/PowerShell invocations of tclsh with -e, anchored to command position (start/pipe/semicolon/paren) so prose mentions in commit messages or grep args do not false-positive; corrective guidance returned to the agent - .gitignore: narrow the .claude ignore so shared settings.json is tracked while session-local files stay ignored - .fossil-settings: ignore-glob hand-derived per the no-negation rule (.claude/* wholesale + explicit fossil add of settings.json), exception set in AGENTS.md updated; fossil extras under-ignore check verified empty Assisted-by: harness=claude; primary-model=claude-fable-5; api-location=anthropic.com	4 weeks ago
