prospec: Skill for Claude Code

.agents/skills/prospec-tasks/SKILL.md

prospec-tasks is a skill for Claude Code, Codex from benwu95/prospec. It costs 71 tokens per session (3,897 once invoked), scanned A, original, MIT.

A task-planning workflow that turns an implementation plan and change specification into an actionable checklist.

In plain words
What is it for?
Use it to organize tasks by architecture layer and mark non-code work such as manual checks or verification.
Why use it?
It breaks a large coding change into smaller work items that are easier to assign and complete.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents; installed under .agents/ (shared by several agents).

This is benwu95/prospec's own configuration. It tells Claude Code and Codex how to work on prospec itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything prospec configures →

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

prospec-tasks 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Prospec Tasks Skill

Activation

When triggered, briefly describe:

  • That you'll read plan.md and delta-spec.md to understand the implementation scope
  • Tasks will be organized by architecture layer following the project's conventions (see references/tasks-format.md)
  • Non-code tasks carry a [M]/[V] kind marker; complexity estimates and [P] markers are optional

Language Policy

Write each generated document in the language the Constitution's Language Policy rule assigns to its path — change artifacts and their archived summaries in the project's artifact language, the trust zone (Knowledge base, Feature Specs, index) in English. One skill run may write both. Free text you pass the CLI that lands in a change artifact follows the artifact language too, leaving its paths, commands, enum values and the fixed prefixes the CLI matches untranslated. Keep code, identifiers, technical terms, and git commit messages in English.

CLI Prerequisite (required)

The prospec CLI is a required file for this skill — its deterministic steps call prospec commands. Probe BEFORE any other step; there is no manual fallback.

  1. Run prospec --version (Bash).
  2. Command not found / not executable → STOP. Ask the user to install the prospec standalone executable — the one-click installer script from the project README (macOS/Linux install.sh, Windows install.ps1) or a release binary from GitHub Releases; prospec is NOT published to npm. Then re-run this skill.
  3. Version older than 2.10.0 → STOP. Report the installed vs required version and ask the user to upgrade, then re-run this skill.

Hand-executing a CLI-owned mutation is NEVER the fallback — that re-introduces the nondeterministic serialization this contract exists to remove.

Startup Loading

  1. [STABLE] Run prospec constitution show --station tasks (Bash)
  2. [STABLE] MANDATORY — Read references/tasks-format.md for tasks.md format
  3. [DYNAMIC] Read .prospec/changes/[name]/plan.md — parse implementation steps
  4. [DYNAMIC] Read .prospec/changes/[name]/delta-spec.md — parse file changes and specifications
  5. [DYNAMIC] Read related module README.md from prospec/ai-knowledge/modules/ (and any {sub-module}.md it links) — confirm architecture layers and dependency directions for task ordering

What ships with it

3 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.

prospec-tasks is a skill published in the GitHub repository benwu95/prospec (6 stars, last pushed yesterday), licensed MIT. It adds 71 tokens to every session and 3,897 once invoked, about $0.0003 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 2026-08-31.
