A coding workflow for taking issues from a project tracker and implementing them in parallel. Each issue is handled in its own Git worktree, which is a separate working copy of the repository.

Use it to pick up tracker issues, turn a planned specification into code, or start several implementation tasks at once.

It keeps changes for different issues separate, reducing conflicts between agents and making parallel work easier to review.

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.

agentmods

npx agentmods add skills/joestump/claude-plugin-sdd/work

Any agent

npx skills add joestump/claude-plugin-sdd --skill work

Clone the repo

git clone --depth 1 https://github.com/joestump/claude-plugin-sdd

Made for: Claude Code, Codex.

Or install sdd, the plugin that ships this one along with the rest of its 20 skills.

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	$0.00044	$0.17935
Opus 5	$0.00022	$0.08968
Sonnet 5	$0.00009	$0.03587
Haiku 4.5	$0.00004	$0.01793

Security

Grade C, and why

work scanned grade C with 1 finding 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 today.

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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

How it starts

The opening of the file, as written. The whole thing — 824 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Work on Issues

Harness portability. This skill runs on any agent harness that loads Agent Skills — Claude Code, Codex CLI, OpenCode, Crush. Tool names used below (AskUserQuestion, Task, TeamCreate, SendMessage, TaskCreate, ToolSearch, mcp__*, ${CLAUDE_PLUGIN_ROOT}) denote capabilities, not hard requirements: map each to your harness's equivalent or use the documented fallback per ${CLAUDE_PLUGIN_ROOT}/references/harness-compat.md. References to CLAUDE.md mean the project memory file (CLAUDE.md, AGENTS.md, or CRUSH.md) per harness-compat § "Project Memory File". A citation of the form shared-patterns.md § "Section" names one ## heading in that file — load only that section (see its "How to Read This File" note), never the whole file.

You are picking up tracker issues and implementing them in parallel using git worktrees. Each issue gets its own worktree and worker agent.

Loop Mode (V1, opt-in). When invoked under /loop with the --loop flag, this skill enters autonomous-mode and uses the lockfile + budget primitives documented in ${CLAUDE_PLUGIN_ROOT}/references/loop-primitives.md (acquired on entry, released on exit) and the telemetry + resume contract documented in ${CLAUDE_PLUGIN_ROOT}/references/loop-telemetry.md (every iteration appends a history.jsonl line and emits a stdout status block; --resume reconciles tracked_prs[] and active_worktrees[] from the last line). The full CLI surface, all 12 stop conditions, and all 6 AskUserQuestion gates are wired in story #144 (SPEC-0020). Without --loop, behavior is unchanged from the rest of this document and no .sdd/loop/ artifacts are created.

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.

work is a skill published in the GitHub repository joestump/claude-plugin-sdd (32 stars, last pushed today), licensed MIT. It adds 44 tokens to every session and 17,935 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
