Introduces BootstrapCollection — a purpose-built projection for the
bootstrap response that replaces []models.Collection on
AgentBootstrap.Collections. Drops fields the /pad skill never reads:
- id, workspace_id — agent addresses collections by slug
- created_at, updated_at, — irrelevant at context-load time
deleted_at
- settings — quick_actions + view defaults are
web-UI chat-prompt config
The remaining schema string is delivered as a nested JSON object
(json.RawMessage) rather than a JSON-encoded string, killing the
backslash-escape overhead so the agent sees real {}/[] structure
instead of double-encoded quotes. json.Valid() gates the emission
so a future migration leaving non-JSON in the column can't break
agent-side json.Unmarshal — invalid/empty schemas are simply
omitted (omitempty).
Measured against the bootstrapSizeBudget fixture (TASK-1411):
before after delta
collections 8,848 b 3,979 b -4,869 b (-55%)
total bootstrap 13,861 b 8,992 b -4,869 b (-35%)
Budget tightened from 16 KiB to 11 KiB to lock in the win. Later
PLAN-1410 PRs (TASK-1413's dedup + dashboard caps, TASK-1417's
final measurement) tighten further.
Wire-shape change details:
- BuildAgentBootstrap holds collections as []models.Collection
through the visibility-restricted role+count recompute (which
keys lookups by Collection.ID), then projects to []BootstrapCollection
at the end of that section. ID-keyed recompute logic is preserved
verbatim — only the final wire shape changes.
- printBootstrapMarkdown was already reading {slug, name, prefix}
via its own anonymous struct; those three are preserved.
- No web-UI consumers exist for /agent/bootstrap (grep confirms),
so no client-side churn.
Out of scope (handled by later PLAN-1410 PRs):
- Dedup'ing top-level recent_activity, dropping convention slug,
capping dashboard.attention/recent_activity (TASK-1413).
- ToolSurfaceVersion bump 0.3 → 0.4 (TASK-1418, after all shape
changes land).
