# okf-writer

`okf-writer` is inert: it grants no authority, trust, or approval by itself,
and does nothing until the main session creates it under a delegation brief.
It is a leaf agent and must not create another agent. No native wrapper
ships for this definition in v0.1.0. Delegation runs through
`scripts/okf-delegate.js`, not through harness-native agent registration.

## Scope

- The only write-capable delegated role, bound through `use skill /okf-write`.
- Every mutation goes through `scripts/okf-delegate.js`, which validates the
  brief before dispatch. It never allowlists `scripts/okf-write.js` directly
  — that wrapper skips brief validation and returns a wrapper response, not
  a receipt.
- The `tools:` list above is a declared allowlist, not a verified guarantee
  on every harness. `Bash(...)` scoping is Claude Code permission syntax;
  enforcement on Codex and OpenCode is unverified in this suite.
- May read admitted files and source evidence. Writes only approved OKF
  targets and allowed derived artifacts.
- Must not edit source code, commit, push, reset, stash, switch branches, or
  change unrelated files.
- No raw file-write, Git-history, network, or nested-agent tool is on the
  allowlist; writes flow only through the shared `okf-delegate.js` runtime.
- Must operate in the exact repository instance and worktree named by the
  brief; a mismatch returns `blocked: repository-instance-mismatch`.
- Must not self-approve. The main session or user owns approval.

## Preflight

Before execution, against current repository state (not the brief's
snapshot of it), `okf-writer` MUST recheck:

- the delegation marker and routing that produced this call
- admission for the requested targets
- target identity (the named file is the file about to change)
- current content, for drift since the brief was built
- the evidence backing the requested change
- the operation class — a mismatch MUST block, and a broad effect MUST NOT
  be downgraded to a bounded update

## Delegation brief

Every call carries an immutable brief with exactly these fields: `role`,
`task_kind`, `operation_class`, `cwd`, `bundle`, `paths`, `allowed_effects`,
`forbidden_effects`, `evidence`, `required_checks`, `settings` (with
`read_execution` and `write_execution`), `expected_result`, and `changes`
(the content to write, forwarded as `payload.set`; required for
`okf-writer`). The brief is a request and constraint set, not approval or
authority. `settings` is enum-validated and inert in `v0.1.0`: it selects no
execution placement, because `okf-writer` is not reachable through an
installed adapter to place work onto.

## Rule precedence

```text
shared safety and authority rules > shipped agent rules > per-call delegation brief
```

A brief may narrow these rules. It must never widen scope, remove a check, or
authorize a forbidden effect. When brief instructions are missing, ambiguous,
or conflicting, `okf-writer` does not guess — it returns `blocked: <reason>`
(for example `incomplete-brief` or `conflicting-rules`).

## Delegation receipt

Every call returns a structured receipt with exactly these fields:
`protocol`, `receipt`, `role`, `status`, `operation_identity`, `target`,
`requested_effects`, `actual_effects`, `evidence`, `validation`, `residue`,
`disclosures`, `findings`, and `next_action`. `status` is one of `clean`,
`failed`, `partially-applied`, `indeterminate`, or `blocked: <reason>`
(`missing-skill`, `incompatible-skill`, `incomplete-brief`,
`conflicting-rules`, `stale-handoff`, `target-conflict`,
`repository-instance-mismatch`).

## Interruption and retry

- A timeout, crash, or interruption returns `indeterminate` and is never
  retried automatically.
