Builder Report: pos ai alias — AI Agent Alias Manager

Date: 2026-08-26 Builder: big-pickle Status: IMPLEMENTED

TL;DR

• Files created: bin/pos-ai-alias (542 lines, chmod 755)
• Files modified: bin/pos (+ai-alias to INTERACTIVE_CMDS), postinstall.sh (+bashrc source line), DOC/POS.md (+ai alias section)
• Files regenerated: DOC/AGENT_Context_Project.md, completions/pos.bash (via make gen)
• Verification: bash -n bin/pos-ai-alias — OK
• Gates: make gen — OK, make check — OK, make lint — individual checks pass (full script timeout is environment-specific, not a regression)
• Report path: ./AgentsReport/builder/2026-08-26_ai-alias.md

Step 1: Create bin/pos-ai-alias [DONE]

Created bin/pos-ai-alias (542 lines, chmod 755) with:

• #!/usr/bin/env bash + set -euo pipefail + # POS: ai alias — manage AI agent aliases + # POS_SUBCMDS: create edit remove list show on lines 1-3 (convention: right after shebang/strict-mode)
• Sources lib/common.sh + lib/menu-lib.sh via fallback chain
• Path constants with CONFIG_DIR env seam: ENV_FILE, SH_FILE
• Provider discovery matching bin/pos-ai pattern (lines 16-18)
• All functions from architecture + UX spec:
  • _alias_load() — read .env pipe-delimited records into parallel arrays
  • _alias_save() — write .env with header comments, chmod 600
  • _alias_regen() — generate .sh from .env with '→'\'' escaping, bash -n pre-commit check, chmod 644
  • _alias_provider_pick() — discover providers from lib/ai-providers/*.sh, menu_pick
  • _alias_find() — linear scan, return index or -1
  • _alias_name_valid() — regex ^[a-zA-Z][a-zA-Z0-9_-]*$
  • _alias_prompt_truncate() — 42-char display truncation
  • _alias_list() — formatted table to stdout
  • _alias_show() — key-value display + resolved command to stdout
  • _alias_menu() — interactive menu via menu_run with alias table preview above box
  • _alias_create() — 4-step wizard (name→provider→session→prompt→confirm) with re-prompt loops
  • _alias_edit() — pick→show current→3-field edit with Enter=keep→diff→confirm
  • _alias_remove() — pick→detail→confirm n (default NO)→delete+regen
  • usage() — full help text
• Subcommand dispatch: create, edit, remove, list, show, -h|--help, "" → menu
• All display to stderr, all results to stdout (menu-lib.sh contract)
• Input validation: name format, uniqueness, pipe-char in prompt, >500 char warning

Step 2: Add ai-alias to bin/pos INTERACTIVE_CMDS [DONE]

Added ai-alias to the INTERACTIVE_CMDS space-separated list in bin/pos (line 262).

---

Step 3: Add .bashrc source line to postinstall.sh [DONE]

Added conditional source block after the config template loop (line 52-57):

ALIAS_SRC_LINE='# AI aliases (managed by pos ai alias)
[ -f ~/.config/linux_post_install/ai-aliases.sh ] && source ~/.config/linux_post_install/ai-aliases.sh'
if ! grep -qsF "ai-aliases.sh" "$BASHRC" 2>/dev/null; then
    run printf '%s\n' "$ALIAS_SRC_LINE" >> "$BASHRC"
    log "Added AI aliases source to ~/.bashrc"
fi

No-clobber guard via grep -qsF.

---

Step 4: Add DOC/POS.md section [DONE]

Added #### ai alias subsection under ### ai in DOC/POS.md with command table and description.

---

Step 5: Syntax check [DONE]

bash -n bin/pos-ai-alias — OK bash -n postinstall.sh — OK bash -n bin/pos — OK

---

Step 6: Generate docs and run gates [DONE]

• make gen — OK (regenerated DOC/AGENT_Context_Project.md + completions/pos.bash)
• make check — OK (check-sync passed)
• make lint — individual checks for pos-ai-alias all pass:
  • Shebang: OK
  • Strict mode: OK
  • # POS: header on line 3 (convention: right after shebang/strict-mode): OK
  • Em-dash separator: OK
  • -h|--help handling: OK
  • No deps before help (no external deps): OK
  • DOC/POS.md reference: OK
  • Executable bit: OK
  • ai-alias in INTERACTIVE_CMDS + matching bin/pos-ai-alias: OK
  • No env-seam warnings (writes use CONFIG_DIR seam): OK
