Implementation Reference

• src/tools/decision-tools.ts:362-395 (handler)

  Registration and handler implementation of the "twining_link_commit" tool within the `registerDecisionTools` function. It calls the engine's `linkCommit` method.

  // twining_link_commit — Link a git commit hash to an existing decision
  server.registerTool(
    "twining_link_commit",
    {
      description:
        "Link a git commit hash to an existing decision. Enables bidirectional traceability between decisions and commits.",
      inputSchema: {
        decision_id: z.string().describe("ID of the decision to link"),
        commit_hash: z.string().describe("Git commit hash to link"),
        agent_id: z
          .string()
          .optional()
          .describe("ID of the agent performing the link"),
      },
    },
    async (args) => {
      try {
        const result = await engine.linkCommit(
          args.decision_id,
          args.commit_hash,
          args.agent_id,
        );
        return toolResult(result);
      } catch (e) {
        if (e instanceof TwiningError) {
          return toolError(e.message, e.code);
