Implements US1, US2, and US3 of spec 016 by layering a marketplace service
on top of existing primitives rather than reinventing them:
- Capability manifests (US2) reuse the wiki subsystem. Each agent publishes
a per-agent article at slug "agent-<name>" and gets versioning, revision
history, and FTS search for free.
- Auction channels (US1) reuse the existing auction channel type, swarm
service, and task/bid store. post_auction / bid / award wrap post_task /
bid_task / accept_bid and attach marketplace metadata (max_budget_tokens,
domains, estimated_tokens, confidence, approach) in the task.requirements
and bid.capabilities JSON blobs. Award converts the auction into a claim
by DM'ing the winner at priority 8 with task_id metadata, so the existing
claim/process/done lifecycle takes over with zero new machinery.
- Reputation ledger (US3) adds migration 018_agent_marketplace.sql with a
new agent_reputation table keyed by (agent_name, domain). mark_task_done
completes the task via the swarm service and writes one ledger row per
declared domain using the reported actual_tokens and success_score.
query_reputation returns a rolled-up summary plus recent entries for a
given (agent, domain) pair — reputation is always a vector, never a
global score (FR-013).
Also:
- Adds the "awarded" reaction type (FR-008) alongside existing approve/
reject/in_progress/done/published. Migration 018 widens the reactions
CHECK constraint via a table rebuild.
- 6 new actions added to the action registry (post_auction, bid, award,
mark_task_done, read_skill_card, query_reputation) so the search tool
can discover them and the execute tool can dispatch them.
- New internal/marketplace package (store.go + service.go).
- New internal/mcp/marketplace.go bridge handlers.
- New internal/mcp/marketplace_test.go covers the full auction lifecycle,
capability manifest publish/read/update, self-bid rejection, non-auction
channel rejection, and reputation summary aggregation.
Out of scope for MVP (deferred per spec prompt): US4 reflection loop,
tombstoning FR-020a/b, multi-owner quorums, auto-escalation on zero bids,
bootstrap exploration credit, epsilon-greedy selection, and the hard-stop
budget enforcement daemon (only soft recording of estimated vs actual is
included).
All existing tests pass; new marketplace tests pass.
