+# Dual-Graph Context Policy
+
+This project uses a local dual-graph MCP server for efficient context retrieval.
+
+## MANDATORY: Adaptive graph_continue rule
+
+**Call `graph_continue` ONLY when you do NOT already know the relevant files.**
+
+### Call `graph_continue` when:
+- This is the first message of a new task / conversation
+- The task shifts to a completely different area of the codebase
+- You need files you haven't read yet in this session
+
+### SKIP `graph_continue` when:
+- You already identified the relevant files earlier in this conversation
+- You are doing follow-up work on files already read (verify, refactor, test, docs, cleanup, commit)
+- The task is pure text (writing a commit message, summarising, explaining)
+
+**If skipping, go directly to `graph_read` on the already-known `file::symbol`.**
+
+## When you DO call graph_continue
+
+1. **If `graph_continue` returns `needs_project=true`**: call `graph_scan` with `pwd`. Do NOT ask the user.
+
+2. **If `graph_continue` returns `skip=true`**: fewer than 5 files  -  read only specifically named files.
+
+3. **Read `recommended_files`** using `graph_read`.
+   - Always use `file::symbol` notation (e.g. `src/auth.ts::handleLogin`)  -  never read whole files.
+   - `recommended_files` entries that already contain `::` must be passed verbatim.
+
+4. **Obey confidence caps:**
+   - `confidence=high` -> Stop. Do NOT grep or explore further.
+   - `confidence=medium` -> `fallback_rg` at most `max_supplementary_greps` times, then `graph_read` at most `max_supplementary_files` more symbols. Stop.
+   - `confidence=low` -> same as medium. Stop.
+
+## Session State (compact, update after every turn)
+
+Maintain a short JSON block in your working memory. Update it after each turn:
+
+```json
+{
+  "files_identified": ["path/to/file.py"],
+  "symbols_changed": ["module::function"],
+  "fix_applied": true,
+  "features_added": ["description"],
+  "open_issues": ["one-line note"]
+}
+```
+
+Use this state  -  not prose summaries  -  to remember what's been done across turns.
+
+## Token Usage
+
+A `token-counter` MCP is available for tracking live token usage.
+
+- Before reading a large file: `count_tokens({text: "<content>"})` to check cost first.
+- To show running session cost: `get_session_stats()`
+- To log completed task: `log_usage({input_tokens: N, output_tokens: N, description: "task"})`
+
+## Rules
+
+- Do NOT use `rg`, `grep`, or bash file exploration before calling `graph_continue` (when required).
+- Do NOT do broad/recursive exploration at any confidence level.
+- `max_supplementary_greps` and `max_supplementary_files` are hard caps  -  never exceed them.
+- Do NOT call `graph_continue` more than once per turn.
+- Always use `file::symbol` notation with `graph_read`  -  never bare filenames.
+- After edits, call `graph_register_edit` with changed files using `file::symbol` notation.
+
+## Context Store
+
+Whenever you make a decision, identify a task, note a next step, fact, or blocker during a conversation, append it to `.dual-graph/context-store.json`.
+
+**Entry format:**
+```json
+{"type": "decision|task|next|fact|blocker", "content": "one sentence max 15 words", "tags": ["topic"], "files": ["relevant/file.ts"], "date": "YYYY-MM-DD"}
+```
+
+**To append:** Read the file -> add the new entry to the array -> Write it back -> call `graph_register_edit` on `.dual-graph/context-store.json`.
+
+**Rules:**
+- Only log things worth remembering across sessions (not every minor detail)
+- `content` must be under 15 words
+- `files` lists the files this decision/task relates to (can be empty)
+- Log immediately when the item arises  -  not at session end
+
+## Session End
+
+When the user signals they are done (e.g. "bye", "done", "wrap up", "end session"), proactively update `CONTEXT.md` in the project root with:
+- **Current Task**: one sentence on what was being worked on
+- **Key Decisions**: bullet list, max 3 items
+- **Next Steps**: bullet list, max 3 items
+
+Keep `CONTEXT.md` under 20 lines total. Do NOT summarize the full conversation  -  only what's needed to resume next session.
