/project-context [subcommand] [arguments]

Manages the project's rolling context file — team-shared knowledge about the codebase that doesn't fit in ADRs or KB entries. Things like "the legacy auth module is fragile", "CI takes 20 min on the full suite", "prod DB has a 5K connection limit we've hit before."

The file lives at PROJECT-CONTEXT.md in the project root (committed, shared with the team).

Subcommands

Pre-flight

If PROJECT-CONTEXT.md does not exist and the subcommand is not add:

No PROJECT-CONTEXT.md found. Add your first entry with:
  /project-context add "<what you've learned about this codebase>"

Stop.

File format — PROJECT-CONTEXT.md

# Project Context

Team-shared knowledge about this codebase. Read by vallorcine agents during
scoping and domain analysis. Entries expire after 90 days by default.

Managed by: `/project-context` — do not edit manually.

---

## Active

### <YYYY-MM-DD> — <one-line summary>
**Expires:** <YYYY-MM-DD>
**Scope:** <"global" | module/area name>
<1-3 sentences of detail.>

---

### <YYYY-MM-DD> — CI takes 20 min on full test suite
**Expires:** 2026-06-16
**Scope:** global
Run focused tests during implementation. Only run full suite in refactor step 2f.

---

## Expired
<!-- Entries moved here by /project-context cleanup. Not read by agents. -->

Size management

• Active section cap: 50 entries or ~200 lines (whichever is hit first)
• When exceeded, /project-context add warns and suggests running cleanup:

  ⚠ Active context has <n> entries (~<n> lines). Consider running:
    /project-context cleanup

• Expired entries in the ## Expired section are not counted toward the cap and are not read by pipeline agents

Scope field

• global — always read by agents when they load project context
• <module/area> — only read when the feature being worked on touches that area (matched against constructs in work-plan.md or the feature description)

project-context add "<entry>" — add a new entry

Display:

───────────────────────────────────────────────
📝 PROJECT CONTEXT · add
───────────────────────────────────────────────

Step 1 — Parse and confirm

Parse the entry text. Ask:

── New context entry ──────────────────────────
  "<entry>"

  Scope: global  (or type a module/area name to scope it)
  Expires: <date 90 days from now>  (or type a date, or: never)

Use AskUserQuestion with options:
  - "Save"
  - "Adjust"

If "Adjust": ask what to change, re-display, confirm again.

### Step 2 — Write

If `PROJECT-CONTEXT.md` doesn't exist, create it with the file header.

Append the new entry to the `## Active` section:
```markdown
### <YYYY-MM-DD> — <one-line summary derived from entry>
**Expires:** <YYYY-MM-DD>
**Scope:** <scope>
<entry text>

Display:

  ✓ Added to PROJECT-CONTEXT.md
    Expires: <date>
    Scope: <scope>

project-context cleanup — review expired and stale entries

Display:

───────────────────────────────────────────────
📝 PROJECT CONTEXT · cleanup
───────────────────────────────────────────────

Step 1 — Scan entries

Read PROJECT-CONTEXT.md. Parse all entries in the ## Active section. For each entry, check:

• Is it past its expiry date? → expired
• Is it within 7 days of expiry? → expiring-soon
• Otherwise → active

Step 2 — Display summary

── Context entries ────────────────────────────
  Active: <n>
  Expiring soon: <n>
  Expired: <n>

If no expired or expiring-soon entries:

  All entries are current. Nothing to clean up.

Stop.

Step 3 — Process expired entries

For each expired entry:

── Expired: <summary> ─────────────────────────
  Added: <date>  |  Expired: <date>  |  Scope: <scope>
  <entry text>

  Type: keep (extend 90d) · archive · delete

• keep → update Expires: to 90 days from today
• archive → move entry from ## Active to ## Expired section
• delete → remove entry entirely

Step 4 — Process expiring-soon entries

For each expiring-soon entry:

── Expiring soon: <summary> ───────────────────
  Added: <date>  |  Expires: <date> (<n> days)  |  Scope: <scope>
  <entry text>

  Type: keep (extend 90d) · archive · skip

Same actions as expired, plus skip to leave it alone.

Step 5 — Summary

───────────────────────────────────────────────
📝 PROJECT CONTEXT · cleanup complete
  Extended: <n>   Archived: <n>   Deleted: <n>   Skipped: <n>
  Active entries remaining: <n>
───────────────────────────────────────────────

project-context (no args) — display all active entries

Display:

───────────────────────────────────────────────

Agent integration

Pipeline agents read PROJECT-CONTEXT.md at these points:

/feature (scoping) — Step 1 (read project config). Read the Active section of PROJECT-CONTEXT.md if it exists. Use global entries and any scoped entries matching the feature description to inform the scoping interview. Do not ask questions that active context entries already answer.

/feature-domains — Step 2 (survey). Check active context entries for known constraints that affect domain classification. An entry like "prod DB has a 5K connection limit" is relevant when the feature involves database work.

/feature-plan — Step 1 (load context). Read active context entries scoped to the modules being planned. Constraints from context entries should be reflected in the work plan contracts.

Pre-flight staleness check: At pipeline start, if PROJECT-CONTEXT.md exists and has expired entries, display:

  ℹ <n> expired project context entries. Run /project-context cleanup to review.

Informational only — never blocks.
