Summary

Creates structured handoff briefings between agents. Use when delegating complex work to subagents that would otherwise lose context. Packages task context, constraints, and progress into a compact packet that subagents can consume without re-reading the full conversation. Preven

1	# context-pack
2
3	## Purpose
4
5	When a parent agent delegates work to a subagent, critical context gets lost — the subagent starts fresh without knowing what was tried, what failed, what constraints apply, or what the parent already decided. Context-pack solves this by creating structured handoff briefings (context packets) that compress the essential information into a compact, parseable format. The packet is small enough to fit in a subagent's system prompt but complete enough to prevent redundant work and constraint violations.
6
7	## Triggers
8
9	- Called by `cook`, `team`, `rescue` before spawning subagents
10	- Called by any L1/L2 skill that delegates work to another skill
11	- Manual: when user says "hand off", "delegate", "split this task"
12
13	## Calls (outbound)
14
15	- `session-bridge` (L3): read persisted state for inclusion in packet
16	- `context-engine` (L3): check current context budget before deciding packet size
17
18	## Called By (inbound)
19
20	- `cook` (L1): before Phase 2-5 subagent spawning
21	- `team` (L1): before dispatching parallel workstreams
22	- `rescue` (L1): before delegating module-level refactoring
23	- `scaffold` (L1): before delegating component generation
24	- Any L2 skill that spawns subagents
25
26	## Data Flow
27
28	### Feeds Into →
29
30	- All subagent invocations: context packet → subagent system prompt
31	- `completion-gate` (L3): packet's success criteria → claim validation baseline
32
33	### Fed By ←
34
35	- Parent agent conversation: decisions, constraints, failed attempts
36	- `session-bridge` (L3): persisted state from prior sessions
37	- `plan` (L2): phase files with task breakdowns
38
39	## Workflow
40
41	1. COLLECT — Gather context from the current conversation:
42	- Task description and user intent (verb-led behavioral phrasing)
43	- Decisions already made (and WHY)
44	- Constraints and hard-stops
45	- Failed attempts (what NOT to do)
46	- Files already read or modified
47	- Current progress state
48	- Type Surface — types / function signatures / contracts that callers cross. These are the durable spine of the brief.
49
50	2. COMPRESS — Reduce to essential information:
51	- Strip conversational noise
52	- Deduplicate repeated context
53	- Prioritize by relevance to the delegated task
54	- Target: <500 tokens for simple tasks, <1500 tokens for complex
55
56	3. STRUCTURE — Format as a context packet (v2 — see Output Format and [references/brief-template.md](references/brief-template.md))
57
58	4. VALIDATE — Check packet completeness:
59	- Does it include the task goal?
60	- Does it include constraints that could cause failure?
61	- Does it include what was already tried?
62	- Does it include `### Out of scope`? (mandatory)
63	- Does it include `### Type Surface` (mandatory if task >= 300 tokens)?
64	- Is it small enough for the target agent's context budget?
65
66	5. PHASE 4.5 — SMELL TESTS — Run mechanical regex gates before emit. See [references/durability-rules.md](references/durability-rules.md).
67
68	\| Regex \| Tier \| Reason \|
69	\|-------\|------\|--------\|
70	\| `\b\S+\.[a-z]{1,4}:\d+\b` \| BLOCK \| file:line reference (e.g., `login.ts:42`) — line numbers go stale \|
71	\| `^- \S*[\\/]\S+\.(ts\\|js\\|py\\|go\\|rs\\|java)\b` outside `### Files Touched` \| BLOCK \| Path-only bullet in narrative \|
72	\| `\b(line \\|on line )\d+\b` \| BLOCK \| "line 42" / "on line 100" \|
73	\| `\b(src\\|lib\\|app)/\S+` in narrative paragraphs \| WARN \| Path mention; verify it belongs in Files Touched section \|
74
75	<HARD-GATE>
76	Any BLOCK-tier match → DO NOT emit. Rewrite the offending lines to use type/function/module names.
77	Missing `### Out of scope` section → DO NOT emit (completion-gate rejects).
78	Missing `### Type Surface` for tasks >= 300 tokens → DO NOT emit.
79	</HARD-GATE>

81	6. EMIT — Send the validated packet to the receiving agent.
