bootstrap

A skill that researches official documentation and writes starter rules for a programming stack not already covered by Clawness. Clawness is a system that applies project-specific rules to coding-agent sessions.

In plain words
What is it for?
Use it to bootstrap rules for stacks such as Ruby, PHP, Elixir, Haskell, C#, Swift, Dart, Scala, or Clojure. It requires approval before writing files because the rules affect later work in the repository.
Why use it?
It gives an uncovered language or framework an initial set of conventions instead of leaving the agent with only generic rules. The rules are written to the project, checked for valid formatting, and used in future sessions.

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

bootstrap 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 2d 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.

Bootstrap rules for an uncovered stack

Clawness ships corpus for ~29 domains. Open a session in a stack it has no rules for and, beyond the always-on mandatory block, it adds little. A SessionStart note says so once and deliberately does nothing else.

This skill is the remedy. The note is only the diagnosis: it fires before you have said what you came for, so it cannot propose a session's worth of work. You invoking this skill is the consent it couldn't ask for.

This is a rule-authoring path, so the same discipline as /clawness:refresh applies. Nothing automatic may invoke it — not the note, not a hook, not your own initiative mid-task. An earlier version of a related feature let the automatic path write rules and it produced heaps of them, consuming a session opened for something else.

Say this before starting. It takes a while, it writes files into the project, and the rules it writes will govern every future prompt in this repo. Get an explicit go-ahead, and tell them nothing is written until they approve the list.

Argument

/clawness:bootstrap [stack] — the ecosystem to write rules for (ruby, elixir, haskell, …). With no argument, use the uncovered stack the note named; if the repo mixes several uncovered stacks, ask which one. One stack per run — a broad pass over several is how a careful review becomes a batch of slop.

Steps

1. Establish what the project actually is

Read enough of the codebase to know the stack, its version, and its shape — the web framework or libraries in use, the build tool, the conventions the existing code already follows. Rules must fit THIS project, not the language in the abstract. A rule the codebase already obeys is noise; a rule that contradicts the house style is worse.

2. Look up current conventions — from documentation, not memory

For each candidate rule, ground it in a current official source: the language or framework's own docs, style guide, or security guidance. Record the URL you used — it becomes the rule's sources and is what makes the rule auditable rather than asserted.

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.

bootstrap is a skill published in the GitHub repository fullymiddleaged/Clawness (3 stars, last pushed 4d ago), licensed MIT. It adds 110 tokens to every session and 1,617 once invoked, about $0.0006 per session on Opus 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.
