shellcheck-fix

A maintenance procedure for checking shell scripts with ShellCheck, a tool that finds common shell-script mistakes, and fixing its findings. The scripts must continue to work with Bash 3.2, the older Bash version included with macOS.

In plain words
What is it for?
Use it after editing `setup.sh`, `context.sh`, or scripts in `scripts/`. It runs ShellCheck, applies compatible fixes, verifies the script headers and strict mode, and smoke-tests the installer when needed.
Why use it?
It catches script problems after `.sh` files change and helps prevent CI failures. It also checks that the installer still works and creates its expected links.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

shellcheck-fix scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Shellcheck Fix

Goal

Keep setup.sh, skills/deepworkplan/shared/context.sh, and scripts/*.sh shellcheck-clean and runnable on macOS's default bash 3.2.

When to use

After editing any shell script, or when CI's shellcheck step fails.

Steps

  1. Run shellcheck setup.sh skills/deepworkplan/shared/context.sh scripts/*.sh.
  2. Fix each finding. When resolving, keep the script bash 3.2-safe:
    • replace mapfile/readarray with while IFS= read -r line; do …; done < <(cmd)
    • replace declare -A with a restructured approach
    • replace ${var^^}/${var,,} with tr '[:lower:]' '[:upper:]'
  3. Confirm each script starts with #!/usr/bin/env bash then set -euo pipefail.
  4. Re-run shellcheck until clean.
  5. If setup.sh changed, smoke-test it: HOME="$(mktemp -d)" ./setup.sh --host claude.

Validation

shellcheck setup.sh skills/deepworkplan/shared/context.sh scripts/*.sh exits 0, and the installer smoke test still creates the expected symlinks.

Notes

Do not change setup.sh public flags (--host, --help) or symlink names without flagging a MAJOR bump. CI runs the smoke job on Ubuntu and macOS.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

shellcheck-fix is a skill published in the GitHub repository DailybotHQ/deepworkplan-skill (20 stars, last pushed 1mo ago), licensed MIT. It adds 35 tokens to every session and 406 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
