Compatibility

Surface	Status
Harness	Main version dsh-v0.1.3-alpha.1 (GitHub tag, verified 2026-09-06: full gate chain + profile install smoke). npm dependency line pinned to 0.1.2-rc.1; peers >=0.1.2-rc.1 <0.2.0.
Node	^22.19.0 || >=24.0.0
Form	Pure-host JS plugin (no browser half)
Model	Any model — repair is deterministic, no extra model calls

What you get

Two independent surfaces, one bundle:

• /translate — the vendor parameter translation table: temperature, top_p, max_tokens, stop, system, and 8 more canonical parameters mapped across 11 vendors (OpenAI, ERNIE, Qwen, Anthropic, Google, DeepSeek, Mistral, Cohere, xAI, Groq, Azure). Ask for a pairwise mapping, list vendors/params, or convert a whole standard request (transformRequest in lib/rosetta.mjs).
• The repair layer — a tools/post-execute listener plus the fix_json tool. When a successful tool result carries broken JSON as a string (string-rooted or json-rooted output schema, or a tool opted in by name), the layer repairs it deterministically: markdown-fence extraction, escape repair, trailing-comma removal, truncation closure, and required-field completion with explicit null placeholders. No value is ever invented — a result that still violates the schema fails closed, and failed tool results are never flipped into successes.

tool result (success, JSON text) ──▶ extract fence ──▶ parse
    │ ok? ──▶ schema-validate ──▶ accept { kind: 'accept', value }  (registry re-validates + re-renders)
    │ broken ──▶ escape / trailing-comma / close / fill-null ──▶ validate
    │ unrepairable ──▶ next()  (original value preserved) + translate/fix audit (counts only)

Quick start

# 1. install the bundle into your profile
dsh plugin --profile web add "github:PerryLink/dsh-translate#main"

# or from npm (published releases)
dsh plugin --profile web add dsh-translate

# 2. restart and verify the row
dsh --profile web --dump-config | grep -A2 'id: dsh-translate'

Then ask the agent to check a mapping or repair a payload:

> /translate openai ernie max_tokens
> Use fix_json to repair: {"a": 1,} against {"type":"object","properties":{"a":{"type":"integer"}},"required":["a"]}

Install & uninstall

• git channel (latest main): dsh plugin --profile web add "github:PerryLink/dsh-translate#main" — pure JS, no build step.
• npm channel (published releases): dsh plugin --profile web add dsh-translate.
• tarball channel: pnpm pack in this repo, then dsh plugin --profile web add ./dsh-translate-<version>.tgz.
• uninstall: dsh plugin --profile web remove dsh-translate (or remove the row from the profile patch).

Configuration

All tunables are Schemastery Config fields (changeable from cordis.yml). An id-targeted override replaces the whole row — restate every key you need. cordis.patch.yml documents each key inline.

Key	Default	Meaning
enabled	true	Master switch; false registers nothing
repair.enabled	true	Post-execute repair layer switch
repair.toolNames	[]	Extra tool names whose JSON-text results may be repaired (on top of string-rooted / json-rooted schemas)
repair.strategies.escapeRepair	true	Escape raw control characters inside strings
repair.strategies.trailingComma	true	Remove commas directly before a closing bracket
repair.strategies.truncationClosure	true	Close an unclosed string or container cut off by truncation
repair.strategies.fieldCompletion	true	Complete missing required fields with explicit null placeholders
repair.maxSteps	8	Strategy application budget (repair-loop passes, 1..64)
diffMaxChars	200	Cap on one logged diff fragment, in characters
diffMaxEntries	50	Cap on logged diff entries
registerCommand	true	Register the /translate command
registerTool	true	Register the fix_json tool
rosettaDataPath	(none)	Optional external rosetta data file (same shape as the bundled lib/rosetta-data.json); overrides the built-in mapping table

Example override in your profile patch:

- insert:
    - id: dsh-translate
      name: dsh-translate
      config:
        enabled: true
        repair:
          enabled: true
          toolNames: ['emit-json']
          strategies:
            escapeRepair: true
            trailingComma: true
            truncationClosure: true
            fieldCompletion: true
          maxSteps: 8
        diffMaxChars: 200
        diffMaxEntries: 50
        registerCommand: true
        registerTool: true

Tools & surfaces

Surface	Kind	Notes
/translate	command	vendors, params, or <from> <to> [param] pairwise mapping
fix_json	tool	{ text, schema?, strategies? } → { ok, repaired?, diff?, strategies, truncated, validated, error? }; diff fragments are bounded and sanitized
post-execute repair	listener	Automatic for successful string results from string-rooted / json-rooted schemas (plus repair.toolNames); always calls next() unless it claims the call

Permissions & data

• Permissions: no network, no subprocess, no credentials — the plugin only consumes the official commands and tools services and appends to the session log.
• Data: repair never fabricates values; the only model-visible additions are the repaired canonical value and the fix_json diff. Session audit events (translate/fix) carry tool name, call id, strategy names, edit counts, and truncation flags — never payloads. The audit write is gated by the host’s session-event vocabulary: hosts that know translate/fix get the plain two-argument append, hosts with the ignorable append envelope get the marked append, and envelope-less hosts (0.1.0-rc.6–0.1.1-rc.2, 0.1.2-rc.1) get no audit append — the tool result remains the model-visible log. 0.1.2-rc.1 (adapted 2026-09-04): the session envelope keeps its ignorable field for stored-log read compatibility only - Session.append still cannot stamp it, so audit-gate behavior is unchanged.

Security boundaries

• Deterministic only. Repair is bounded text surgery; the upstream LLM-retry arm of JSON-Schema-Enforcer-Proxy was deliberately not ported — a post-execute listener never calls a model.
• Fail closed. Unrepairable syntax and schema violations leave the original result untouched (or return a structured error from fix_json); null placeholders only land when the schema accepts null.
• Hostile input bounded. Unsupported schema keywords and circular schemas are rejected; oneOf validation is capped by depth (MAX_ONE_OF_DEPTH) and a branch budget (MAX_ONE_OF_BUDGET), so an exponential schema cannot exhaust the process.
• No payload leakage. Logs and audit events never contain repaired payloads; diffs are truncated and capped before display or storage.

Known limitations

• The supported JSON Schema subset mirrors the harness tool registry (type/oneOf/properties/required/additionalProperties/items/enum/const); other keywords are rejected as unsupported, not silently ignored.
• Repair only applies to successful results whose canonical value is a JSON-text string; a value that already failed schema validation arrives as a failed result and is never flipped.
• The translation table covers 11 vendors × 13 canonical parameters; extended rows follow public API references (not the upstream trio) and are marked as such in lib/rosetta.mjs.
• On hosts that neither know translate/fix nor expose the ignorable append envelope — the published 0.1.0-rc.6–0.1.1-rc.2 line and 0.1.2-rc.1, which fails closed on unknown event types at read — the adaptive gate skips the audit append so the session log is never polluted; the in-log audit mirror is lost on those hosts until the event type is registered.
