When a tool creates files as part of its job (e.g. `npm install`, `pytest --junitxml`), that is Bash's job — the prohibition is on using shell/Python as a *manual file-content transport*. + +**Never use shell/Python as a manual file-content transport:** +- `cat > /tmp/script.py << "PYSCRIPT" && python3 /tmp/script.py` — write a file instead +- `tee file.md << "EOF"` — write a file instead +- any heredoc that writes textual project-file content + +**Escape clause:** If a dedicated tool genuinely cannot handle the operation (e.g. binary file, byte-precise output, network call), Bash is permitted. This clause applies only to *tool capability* gaps — not to tools being blocked or failing. Add a one-line comment explaining why the dedicated tool is insufficient. + +**When a dedicated tool is blocked or fails:** stop immediately, investigate why (hook? permission? path issue?), then ask the user. Never chain Bash workarounds as a substitute for a blocked tool.

Announce route in one line before starting. Before any non-trivial implementation: call `mcp__orchestrator__route_task(description)` and follow its decision. +**Skill invocation:** When a skill matches the current task (`/check`, `/run`, `/orchestrate`, etc.), invoke it.

Never let commits accumulate locally. +- At the start of a session: run `git status` and `git log origin/main..HEAD`. When unpushed commits exist: notify the user immediately. +- When pushing: use `git push origin main` (or the current branch name). Never force-push without explicit user approval. + +## Post-Commit/Push Discipline (MANDATORY — ENFORCED BY HOOK — NEVER BYPASS) + +After every `git commit` or `git push`: immediately inspect the command output for errors. + +**If the commit or push failed for ANY reason:** +1. STOP all other work immediately. +2. Read the full error output. Diagnose the root cause. +3. Fix the underlying issue (never patch around it). +4. Re-run the commit or push. +5. Verify the re-run exits cleanly with no errors. + +**Zero tolerance for unresolved failures:** +- A failed commit is not "tried" — it did not happen. Treat it as if the code is unsaved. +- A failed push means the remote does not have the code. Fix and push before continuing. +- Never proceed to the next task while a commit or push is in an error state. +- Never use `--no-verify` or any bypass mechanism. Fix the code, not the gate. +- An interrupted commit/push (cancelled mid-execution) counts as a failure — resolve it. + +**Enforced automatically by `post-commit-push-gate.sh` (PostToolUse hook on Bash).

If any file fails validation, `update.ps1` automatically runs `git reset --hard ` on that machine and marks the update as failed. The developer will see `PREFLIGHT FAIL: : `. This is expected behavior — fix the upstream commit and the next pull will succeed. + +**Rollback procedure:** +1. `git revert ` (never force-push) +2. `git push origin main` — `update.ps1` auto-rollback on each machine clears the bad state on next pull +3. Notify team of the revert via the usual channel + +## Database Protection (CRITICAL -- NEVER VIOLATE) + +Enforced automatically by `protect-db.sh` hook -- blocks destructive commands on DB paths. + +- When encountering any database file or directory (`*.db`, `*.sqlite`, `*.sqlite3`, `*chroma*`, `chroma_db/`, `pgdata`, `*redis*data`, `*mongo*data`, `*elastic*data`, `*mysql*data`, `*_db/`): NEVER delete it. Zero exceptions. +- Before any destructive operation on a DB path: create a backup first: + 1. `cp -r _archive/_backup_$(date +%Y-%m-%d)/` + 2. Verify: `ls -la _archive/_backup_*/` + 3. Only then proceed. +- Allowed operations: backup, copy, archive, read. Forbidden: `rm -rf`, `rmdir`, `shutil.rmtree()`, `DROP TABLE/DATABASE`, `docker volume rm`. +- When adding a new database to a project: add its path pattern to `hooks/protect-db.sh` `DB_PATTERN` and run `/sync`. + +## Session Start Protocol + +At the start of each session, execute these steps in order: +0. **Detect session scope** (silently — NO visible bash calls): + a. Check conversation context for `[SESSION]` tag injected by sync-check.py SessionStart hook. This tag is always present when the hook runs. Parse it: + - `[SESSION] label=X source=env|branch|file|single-plan ...` → SESSION_LABEL=`X` (explicit or auto-detected). + - `[SESSION] default escape=true` → force no-session mode, skip to step f. + - `[SESSION] default branch=...` → no session, skip to step f. + b. **Bash fallback** (ONLY if no `[SESSION]` tag in context — e.g. hook didn't run): Run `Bash: S="${CLAUDE_SESSION:-}"; B="$(git branch --show-current 2>/dev/null)"; echo "S=$S B=$B"`. Parse `S` and `B` as before. + c. If `S` non-empty and `_`: force no-session mode — skip to step f. + d. If `S` non-empty and not `_`: validate `^[A-Za-z0-9][A-Za-z0-9_-]{0,63}$`. If invalid: ABORT. SESSION_LABEL=`{S}`. Skip to step e. + e. If SESSION_LABEL set: PLAN_FILE=`docs/PLAN-{SESSION_LABEL}.md`, TASKS_FILE=`docs/TASKS-{SESSION_LABEL}.md`, REVIEW_FILE=`docs/REVIEW-{SESSION_LABEL}.md`. Report to user: "Session: **{SESSION_LABEL}** → {PLAN_FILE}". + f. If SESSION_LABEL not set: PLAN_FILE=`docs/PLAN.md`, TASKS_FILE=`docs/TASKS.md`, REVIEW_FILE=`docs/REVIEW.md`. Do NOT print "no session" — just proceed silently to step 1. + + **Detection priority** (hook resolves in this order): env var > branch > `.claude/.session` file > single PLAN-*.md auto-detect > default. Skills add args-based detection (between branch and `.session`) as a skill-only priority. The hook validates `.session` label against `docs/PLAN-{label}.md` existence and cleans up stale files automatically. +1. Read PLAN_FILE -- check for in-progress plans. +2. Read `docs/ROADMAP.md` -- check current phase status. +3. Call `list_active_pipelines(project=)` -- ALWAYS pass project. Prefix matching on the server returns all sessions for this project and excludes foreign pipelines. +4. Check the `[SYNC CHECK]` line from the SessionStart hook output: + - Out of sync: report the stale files to the user and ask if they want to run `/sync`. + - In sync: confirm to the user ("rules are up to date"). + - No `[SYNC CHECK]` line (unmanaged project): skip silently. +5. When active pipelines exist: report them to the user with resume instructions before accepting new tasks. +5b. Call `index_ops(action="orphan_scan", project=, root_path=)` to scan for stale pipelines. For each result: if `auto_cancel_safe=True` (risk_level="low"), auto-cancel via `pipeline_ops(action="cancel", pipeline_id=id, reason="orphan auto-cancel: stale >72h, HEAD contains commit, no unpushed")`. Report remaining `high` risk pipelines to the user for manual review. Do not leave orphans. +6. When other pending work exists: report it before accepting new tasks. + +## Project & Pipeline Isolation (CRITICAL — NEVER VIOLATE) + +**Scope rule:** Every session operates within ONE project (the current working directory). All actions — file reads, edits, pipeline operations, git commands — MUST stay within the current project scope unless the user **explicitly names** another project and requests a cross-project action. + +**Forbidden without explicit user instruction:** +- Reading, modifying, or deleting files in other projects' directories +- Resuming, completing steps in, or cancelling pipelines that belong to other projects +- Running git commands in other projects' repositories +- Making assumptions about other projects' state based on shared pipeline lists + +**Pipeline isolation:** Always pass `project=` to `list_active_pipelines` — server-side prefix matching excludes foreign pipelines. Never call without project filter in production use. + +## Per-Phase Gate (MANDATORY) + +Before starting any new implementation phase from PLAN_FILE (see Session Start Protocol step 0): +1. Run automated tests (`npm test`, `pytest`, etc.) — must pass with zero failures. For new code paths introduced in this phase: verify by reviewing the diff and new test files that corresponding tests exist — not just that existing tests pass. +2. Call `mcp__pal__codereview` on all files changed in the previous phase. Any CRITICAL, HIGH, or MEDIUM → HALT, fix, re-review. +3. Call `mcp__pal__thinkdeep` on the previous phase's changes. Any CRITICAL, HIGH, or MEDIUM → HALT. +4. If PAL MCP is unavailable: perform steps 2-3 using internal cross-model review (Agent tool, different model tier). Document which fallback model was used. +5. Only after all three pass: mark the previous phase complete in PLAN_FILE (`[x]`) and proceed to the next. +6. When the gate passes but no further incomplete phases remain in PLAN_FILE (i.e., every phase's GATE checkpoint is marked `[x]`): invoke the `/finish` skill automatically. Never leave a completed plan without running `/finish`. + +Never skip this gate. Never proceed to the next phase while the previous phase has unresolved CRITICAL, HIGH, or MEDIUM findings. Zero MEDIUM+ required at every phase gate — code must be clean at each phase boundary, not only at the end-of-plan audit. + +**TDD advisory:** For features and bugfixes: write the failing test first, verify it fails, then implement. For refactoring: ensure existing tests pass before and after. Exception: spike/exploratory work where the interface is not yet defined. +If a PAL finding is believed to be a false positive: use `mcp__pal__challenge` to contest it, or escalate to the user. Never silently skip or downgrade findings. + +## Parallel Sessions + +For parallel work setup, session detection order, label naming rules, and scoping details: see `/new-session` skill. + +## Context & Token Optimization (MANDATORY) + +- Before moving to a different feature, phase, or task domain: commit all current work and update `docs/`.
