What it does

Bash Script Generator is an agent skill from akin-ozer/cc-devops-skills. Create, generate, write, or scaffold bash/shell scripts (.sh), automation, or CLI tools.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including scripts and assets (for example `assets/templates/standard-template.sh`, `docs/bash-scripting-guide.md` and `docs/generation-best-practices.md`).

It sits in Development, covering Shell scripting. It works with Bash. The repository describes itself as: DevOps skills for Claude Code and Codex. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Shell scripting

Example prompts

  • “/bash-script-generator”

Requirements

  • A Bash shell

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Preflight
  2. Capture Requirements
  3. Choose Generation Path
  4. Load Only Relevant References
  5. Generate Script
  6. Validate and Iterate
  7. Final Response Contract

What it can do on your machine

Read from SKILL.md and the folder at commit 276af75. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 3 files in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • bash
    • sh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • gnu.org
    • pubs.opengroup.org
    • shellcheck.net

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Bash Script Generator loads about 1.7k tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 671 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~28
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Bash Script Generator

Overview

Generate production-ready Bash scripts with clear requirements capture, deterministic generation flow, and validation-first iteration.

Trigger Phrases

Use this skill when the user asks to:

  • Create, generate, write, or build a Bash/shell script
  • Convert manual CLI steps into an automation script
  • Build a text-processing script using grep, awk, or sed
  • Create an operations helper script, cron script, or CI utility script

Do not use this skill for validating an existing script only. Use devops-skills:bash-script-validator for validation-only requests.

Execution Model

Follow stages in order. Do not skip a stage; use the documented fallback when blocked.

Stage 0: Preflight
  1. Confirm scope and target output path.
  2. Confirm shell target:
  • Default: bash
  • If portability is requested: POSIX sh
  1. Check capabilities and pick fallback path:
CapabilityDefault PathFallback Path
Requirement clarificationAskUserQuestion toolAsk same questions in normal chat; mark unresolved items as assumptions
Script scaffoldbash scripts/generate_script_template.sh ...Copy assets/templates/standard-template.sh manually or hand-craft minimal scaffold
Validationdevops-skills:bash-script-validatorLocal checks: bash -n, shellcheck if available, sh -n for POSIX mode

If a fallback path is used, state it explicitly in the final summary.

Stage 1: Capture Requirements

Collect only what is needed to generate the script correctly:

  • Input source and format
  • Output destination and format
  • Error handling behavior (fail-fast/retry/continue)
  • Security constraints (sensitive data, privilege level)
  • Performance constraints (large files, parallelism)
  • Portability requirement (Bash-only vs POSIX)

Then create a Captured Requirements table with stable IDs.

markdown
## Captured Requirements

| Requirement ID | Description | Source | Implementation Plan |
|---|---|---|---|
| REQ-001 | Parse nginx logs from file input | User | `parse_args()` + `validate_file()` + `awk` parser |
| REQ-002 | Output top 10 errors | User | `analyze_errors()` + `sort | uniq -c | head -10` |
| REQ-003 | Handle large files efficiently | Assumption | Single-pass `awk`; avoid multi-pass loops |

Rules:

  • Every major design decision maps to at least one REQ-*.
  • Keep assumptions explicit and minimal.
Stage 2: Choose Generation Path

Use this deterministic decision tree:

text
Need multi-command architecture, unusual control flow, or strict non-template conventions?
├─ Yes -> Custom generation
└─ No
   Need standard CLI skeleton (usage/logging/arg parsing/cleanup)?
   ├─ Yes -> Template-first generation
   └─ No -> Custom generation

Template-first is the default for single-purpose CLI utilities.

Stage 3: Load Only Relevant References

Use progressive disclosure. Read only docs needed for the current request.

NeedReference
Tool choice (grep vs awk vs sed)docs/text-processing-guide.md
Script structure and argument patternsdocs/script-patterns.md
Strict mode, shell differences, safetydocs/bash-scripting-guide.md
Naming, organization, and quality baselinedocs/generation-best-practices.md

Citation format (required):

  • [Ref: docs/<file>.md -> <section>]
Stage 4: Generate Script
Path A: Template-first (default)
  1. Generate scaffold:
bash
bash scripts/generate_script_template.sh standard output-script.sh
  1. Replace placeholders and add business logic.
  2. Keep logging to stderr and data output to stdout unless requirements say otherwise.
  3. Add comments only where logic is non-obvious.
Path B: Custom generation

Build a script with at least:

  • Shebang and strict mode
  • usage()
  • parse_args()
  • Input validation and dependency checks
  • Main workflow function(s)
  • Predictable exit codes
Show full SKILL.md (284 more words)Show less
Stage 5: Validate and Iterate

Default validation path:

  1. Invoke devops-skills:bash-script-validator
  2. Apply fixes
  3. Re-run validation
  4. Repeat until checks pass or blocker is identified

Fallback validation path (when validator skill is unavailable):

bash
# Deterministic local gate for this skill:
bash scripts/run_ci_checks.sh --skip-shellcheck

# CI gate (shellcheck required):
bash scripts/run_ci_checks.sh --require-shellcheck

If any check is skipped, include Skipped check, Reason, and Risk in the output.

Stage 6: Final Response Contract

Always return:

  1. Generated script path
  2. Requirements traceability (REQ-* -> implementation)
  3. Validation results with rerun status
  4. Citations in standard format
  5. Any assumptions/fallbacks used

Canonical Example Flows

Example A: Full Flow (Template-first)
  1. Clarify missing data format and output expectations.
  2. Capture REQ-* table.
  3. Choose template-first path.
  4. Generate scaffold with scripts/generate_script_template.sh.
  5. Implement logic and map functions to REQ-*.
  6. Validate with devops-skills:bash-script-validator and rerun until clean.
  7. Return final summary with citations.
Example B: Constrained Environment Flow

Use this when AskUserQuestion, validator skill, or shellcheck is unavailable:

  1. Ask clarifying questions in chat.
  2. Mark unresolved items as assumptions in Captured Requirements.
  3. Generate from template script or template file copy fallback.
  4. Run bash -n (and sh -n if relevant).
  5. If shellcheck is missing, report skip with risk and mitigation.

Done Criteria

The task is complete only when all items are true:

  • Trigger matched and scope confirmed
  • Captured Requirements table exists with REQ-* IDs
  • Template-first vs custom decision is documented
  • Script is generated with deterministic structure
  • Validation executed and rerun policy applied
  • Any skipped checks include explicit reason and risk
  • Final response includes traceability, citations, and assumptions

  • Deterministic CI gate: scripts/run_ci_checks.sh
