What it does
Subduction Policy is an agent skill from dxos/dxos. Reference for SubductionPolicy (the four hooks authorizeConnect, authorizeFetch, authorizePut, filterAuthorizedFetch passed via Subduction.hydrate(..., policy) or new Repo({ subductionPolicy })). Use when designing client-side access control over Subduction-replicated data, choosing which hook to deny in, or debugging why a doc did or did not replicate.
Its SKILL.md is about 3.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/sync-reliability.md`).
It sits in Backend & APIs, covering Authorization and RBAC. The repository describes itself as: TypeScript implementation of the DXOS protocols, SDK, toolchain and Composer.
When your agent uses it
- Designing client-side access control over Subduction-replicated data
- Choosing which hook to deny in
- Debugging why a doc did
- Did not replicate
Example prompts
- “/subduction-policy”
What it can do on your machine
Read from SKILL.md and the folder at commit 2e6b92a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Subduction Policy loads about 3.4k tokens when it runs, and up to ~8.8k if it reads all its reference files. Until then it costs about 97 tokens; SKILL.md has 1,334 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,334 words (~3,368 tokens).
“SubductionPolicy is the JS-imported policy object the Subduction Wasm bridge consults for every authorization decision. The TypeScript shape (verbatim from subduction_wasm/src/policy.rs's TS_POLICY block):”
