inkwell-agent-sandboxes-and-software-factory: Skill for Claude Code

.claude/skills/sssf/SKILL.md

sssf is a skill for Claude Code from disler/inkwell-agent-sandboxes-and-software-factory. It costs 82 tokens per session (1,757 once invoked), scanned A, a copy of sssf, MIT.

A software factory for running repeatable workflows in which coding agents work through bounded stages such as planning, building, testing, reviewing, and documenting.

In plain words
What is it for?
Use it to install, create, run, or update agent workflows, manage the agent roster, and observe active workflows.
Why use it?
It keeps task order, retries, acceptance checks, shared context, and run records under defined control instead of leaving them to improvised agent behaviour.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter.

This is disler/inkwell-agent-sandboxes-and-software-factory's own configuration. It tells Claude Code how to work on inkwell-agent-sandboxes-and-software-factory itself, so it is not a mod to install elsewhere.

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

sssf 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 2mo ago.

The scan reads SKILL.md. This mod also ships 26 executable files (apps/visualizer/server/db.ts, apps/visualizer/server/index.ts, apps/visualizer/shared/types.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Super Simple Software Factory (SSSF)

Reusable combination of agents plus code: deterministic Python ADW scripts own sequencing, retries, and acceptance; coding agents (Pi in v1) work inside bounded phases; typed JSON envelopes carry context between them; everything streams into SQLite for the polled visualizer. Agent proposes, code disposes.

Startup

Three steps. Then stop.

  1. Read cookbooks/sssf_overview.md — the system map.
  2. ls adws/adw_*.py and read each file's Phases: docstring line.
  3. Print the ADWs as a table — name, the chain, one line on when to reach for it — and wait for the engineer's request.
| ADW | Chain | Use when |
|---|---|---|
| adw_scout | engineer → scout | read-only recon; nothing changes |
| adw_simple_sdlc | plan → build → test → review → document, 3 commits | the work is real and its shape is not obvious |

Nothing else. No trace-db queries, no reading the config or the ADW scripts' bodies, no repo inventory, no last-runs summary, no diagnosing an old failure, no "current state" dashboard. None of it was asked for, and it is not free:

  • Volunteered state is guessed state. An orchestrator that improvised a status board queried a runs table and a payload column — neither exists (sessions, payload_json). The spec that would have said so is references/observability.md, one lazy read away. Probing to look prepared is how you end up confidently wrong in your first message.
  • It spends the context the real task needs, before you know what the task is.
  • It is stale on arrival. State printed before the request describes a system that the very next run changes.

Everything else — the db schema, the roster, the handoff contract — is lazy-loaded through the routing table below, when a request actually calls for it. Reading it early defeats the mechanism.

Two exceptions, both narrow: if the engineer's first message already contains a request, skip the waiting and route it; and if the factory is plainly not installed (no adws/, no config), say that in one line instead of the table.

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.
