A repository-based workflow for AI-assisted software development that moves from a written specification to implementation and verification.

Use it to initialize a project workspace, plan and execute milestones, verify changes, audit progress, and complete or start new milestones.

It gives development work a repeatable structure and keeps plans, phases, research, and checks in the project itself.

Workspine — Skill for Claude Code and Codex by PatrickSys

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add PatrickSys/workspine --skill distilled

Clone the repo

git clone --depth 1 https://github.com/PatrickSys/workspine

Made for: Claude Code, Codex.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.

Model	Per session	Once invoked
Fable 5.1	$0.00024	$0.00869
Opus 5.5	$0.00010	$0.00348
Sonnet 5.5	$0.00005	$0.00174
Haiku 4.5	$0.00002	$0.00087

Security

Grade A, and why

Workspine 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 1mo 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.

Behavior:

Always: generates open-standard skills at .agents/skills/work-*/SKILL.md by embedding distilled/workflows/*.md, plus repo-local deterministic helpers at .work/bin/gsdd.mjs (or .planning/bin/gsdd.mjs in legacy workspaces).
Optional: generates tool adapters (root AGENTS.md, Claude .claude/skills + .claude/commands alias + .claude/agents, OpenCode .opencode/commands + .opencode/agents, Codex CLI .codex/agents/work-plan-checker.toml).
Codex CLI: uses the portable skill entry surface and the generated .codex/agents/ checker/approach-explorer agents; it does not use .codex/AGENTS.md as the primary integration path.
Root AGENTS.md is only written when explicitly requested (so we do not pollute existing user governance).

Core:

.work/templates/spec.md -> .work/SPEC.md
.work/templates/roadmap.md -> .work/ROADMAP.md

Research:

.work/templates/research/*.md -> .work/research/*.md

Brownfield codebase mapping:

.work/templates/codebase/*.md -> .work/codebase/*.md

Files

What ships with it

48 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

Workspine is a skill published in the GitHub repository PatrickSys/workspine (59 stars, last pushed 8d ago), licensed MIT. It adds 24 tokens to every session and 869 once invoked, about $0.0001 per session on Opus 5.5. 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.

Use when a task is too large for turn-by-turn orchestration and should run through the big-task workflow lane: system-wide changes, large migrations, repo-wide audits, high-confidence verification, or tasks explicitly asking to run a workflow.
