refactor(link-skills): scaffold the module layout and move the output and names sections - #31
Conversation
scripts/link-skills.sh is 4066 lines, over the 500-line limit AGENTS.md sets. This is the first layer of the split: it makes the script an entry point that sources topic modules, and moves the first two topics out. The entry point keeps the header, the globals and the two load-time overrides. script_abs_path and resolve_symlink_path move up from the paths section, above the source list, because the loader needs them to find the real file behind a symlink. boot_fail reports a module that will not load and stops: one line and exit 2, or the bracketed line and exit 0 when the run is a session hook, so a session start still ends well. The "[ -r ]" test before each "." is what makes that reachable: "." is a special builtin, so on bash 3.2 an operand it cannot read ends the shell before "|| boot_fail" runs. SCRIPT_PATH is assigned at load time now; main assigns the same value again until main is split. scripts/lib/link-skills/output.sh holds info, err, warn, die and hook_say byte for byte. usage was 64 lines, over the function limit, so it becomes three bare calls to usage_head, usage_options and usage_notes, which print the same arguments in the same order. The SC2016 directive moves from above usage to the printf in usage_options, the one that holds the literal $HOME. scripts/lib/link-skills/names.sh holds the names and casing section byte for byte. CASE_INSENSITIVE and HOOK_MODE are assigned in the entry point and read in a module, so each carries an SC2034 directive naming its reader. The harness copies both the script and its modules into a fixture now. fixtures_install_script replaces the six cp calls that copied the script alone, SOURCE_LIB names the module directory, and harness_require_subject refuses a run without it. A new case, help_prints_usage, runs help, -h and --help and compares the three outputs, so a split help text cannot drift. Validation: pnpm check:shell with SHELL_SIZE_BASE=origin/main, shellcheck over every tracked .sh file, node scripts/validate-skills.mjs, pnpm test:scripts, and both harness passes at 145 passed, 0 failed, 0 skipped.

- Around line 25-41: Update the help-output checks in the relevant test case to
invoke all three help commands directly with BASH_BIN and LS, redirecting
complete stdout and stderr to files and recording LS_RC. Load the primary output
only for content assertions, then use cmp to compare the raw files for -h and
--help so trailing newlines are preserved.

boot_fail treated a literal "hook" anywhere in argv as a hook run. A non-hook command whose option operand is named hook, such as "link-skills.sh check --sources hook", therefore printed the bracketed hook line and exited 0 when a module would not load, although the documented contract for every non-hook command is one line on stderr and exit 2. boot_fail now reads the command by main's own rule: the first argument that is neither an option nor the operand of --sources or --assembly, with -h and --help naming help wherever they sit. The option parser has still not run at this point, so the rule is copied rather than shared. The size baseline entry follows the file from 3937 to 3951 lines. That is 115 below the 4066 lines this branch's base carries, so the ratchet against main still moves down. Verified against a staged install with output.sh removed, under bash 5 and /bin/bash 3.2.57: "hook" and "--sources hook hook" exit 0, while "check", "check --sources hook", "--sources=hook check", "--assembly hook link", "hook --help" and a run with no arguments exit 2.

Review round 1 closed at
On the Claude review's "not independently verified" note, the gates were re-run locally at this head: harness 145 passed, 0 failed, 0 skipped under Two things for whoever rebases the stack. This round changes |
help_prints_usage captured each spelling through case_run_script, which reads the run with a command substitution. That drops every trailing newline, so a difference in the last bytes of one spelling would never reach LS_OUT and the case would pass. The case now runs each spelling into a file of its own under CASE_DIR and compares the files with cmp, the way install-hooks-settings.sh already does. LS_OUT and LS_RC are still set from that run, so the assertions that read the text rather than compare it are unchanged. The case count stays at 145.

tl;dr
The installer that assembles shared agent skills was one 4,066-line script. This change starts breaking it into topic files and moves the printing and name-checking parts out first. Every command behaves and prints exactly as before, so nothing changes for anyone using it.
The Problem
scripts/link-skills.shwas 4,066 lines, far past the 500-line limitAGENTS.mdsets for shell files.The Solution
scripts/lib/link-skills/and sourceoutput.sh(the report levels, the refusal, the hook line, the help text) andnames.sh(name and case rules) by absolute path from an explicit ordered list.script_abs_path,resolve_symlink_pathandboot_fail;boot_failnames a module that will not load and exits 0 in hook mode, 2 otherwise. It reads the command by main's own rule, so an option operand namedhookis not mistaken for a hook run.usageintousage_head,usage_optionsandusage_notesto fit the 50-line function limit. The help text is byte-identical tomain.fixtures_install_script. The help case compares the three spellings as files, so a trailing-newline difference cannot slip past a command substitution.AGENTS.mdandREADME.mdrecord the new layout.Validation
