Evolve an Existing Team

Fix, restructure, or make specialized variant of team first made with create-team. This proc covers upkeep side of team life: check gaps vs template and coord patterns, apply tight fixes to composition and flow, bump versions, keep registry and cross-refs in sync.

When Use

• Team member roster stale after agents added, removed, or evolved
• User feedback shows flow bottlenecks, unclear handoffs, or missing views
• Coord pattern no longer fits team real flow (e.g., hub-and-spoke should be parallel)
• Specialized variant needed next to original (e.g., r-package-review and r-package-review-security-focused)
• Team member roles overlap and need sharper edges
• CONFIG block out of sync with prose desc or members list
• Team needs split into two smaller teams or two teams need merge

Inputs

• Required: Path to existing team file to evolve (e.g., teams/r-package-review.md)
• Required: Evolve trigger (feedback, new agents, coord mismatch, scope overlap, perf issues, agent evolve)
• Optional: Target version bump size (patch, minor, major)
• Optional: Make specialized variant vs refine in-place (default: refine in-place)

Steps

Step 1: Assess the Current Team

Read existing team file and check each section vs team template (teams/_template.md):

Section	What to Check	Common Issues
Frontmatter	All required fields (name, description, lead, version, author, coordination, members[])	Missing tags, stale version, wrong coordination
Purpose	Clear multi-agent justification (at least two distinct specialties)	Could be handled by a single agent
Team Composition	Table matches frontmatter members, no overlapping responsibilities	Stale table, duplicated focus areas
Coordination Pattern	Matches actual workflow, ASCII diagram present	Wrong pattern for the workflow
Task Decomposition	Phased breakdown with concrete tasks per member	Vague tasks, missing phases
CONFIG Block	Valid YAML between markers, matches frontmatter and prose	Out of sync, missing blocked_by, invalid YAML
Usage Scenarios	2-3 realistic activation prompts	Placeholder text
Limitations	3-5 honest constraints	Missing or too generic
See Also	Valid links to member agents, related teams, guides	Stale links

# Read the team file
cat teams/<team-name>.md

# Verify all member agents still exist
grep "id:" teams/<team-name>.md | while read line; do
  agent=$(echo "$line" | grep -oP '(?<=id: )[\w-]+')
  grep "id: $agent" agents/_registry.yml || echo "MISSING: $agent"
done

# Check if the team is referenced by any guide
grep -r "<team-name>" guides/*.md

Got: List of specific gaps, weak spots, or fix chances sorted by section.

If fail: Team file not exist or no frontmatter? This skill not apply — use create-team instead to make from scratch.

Step 2: Gather Evolution Requirements

Spot and sort what fired evolve:

Trigger	Example	Typical Scope
User feedback	"Reviews take too long, agents duplicate effort"	Sharpen responsibilities or change pattern
New agent available	api-security-analyst agent was created	Add member
Agent evolved	code-reviewer gained new skills	Update member responsibilities
Agent removed	deprecated-agent was retired	Remove member, reassign tasks
Coordination mismatch	Sequential team has independent subtasks	Change to parallel
Scope expansion	Team needs to cover deployment, not just review	Add member or create variant
Team too large	6+ members causing coordination overhead	Split into two teams
Team too small	Single member does most of the work	Merge with another team or add members

Log specific changes needed before edit:

- Frontmatter: add new member `api-security-analyst` with role "API Security Reviewer"
- Team Composition: add row to composition table
- Task Decomposition: add API security review tasks to execution phase
- CONFIG block: add member and tasks entries
- See Also: add link to new agent file

Got: Concrete list of changes, each mapped to specific section of team file.

If fail: Changes unclear? Ask user for clarity before go on. Vague evolve goals give vague fixes.

Step 3: Choose Evolution Scope

Use this pick matrix to decide refine in-place or make variant:

Criteria	Refinement (in-place)	Specialized Variant (new team)
Team ID	Unchanged	New ID: <team>-<specialty>
File path	Same .md file	New file in teams/
Version bump	Patch or minor	Starts at 1.0.0
Coordination	May change	May differ from original
Registry	Update existing entry	New entry added
Original team	Modified directly	Left intact, gains See Also cross-reference

Refinement: Pick when tune members, sharpen roles, fix CONFIG block, or change coord pattern. Team keeps its identity.

Variant: Pick when evolved version would serve different use case, need different coord pattern, or target different audience. Original stays as-is for its existing use case.

Extra scope picks:

Situation	Action
Team has 6+ members and is slow	Split into two focused teams
Two teams of 2 cover adjacent domains	Merge into one team of 3-4
Team's coordination pattern is wrong	Refinement — change pattern in-place
Team needs entirely different lead	Refinement if lead exists; create agent first if not

Got: Clear pick — refine, variant, split, or merge — with reason.

If fail: Unsure? Default to refine. Split or merge teams has bigger blast radius and should be confirmed with user.

Step 4: Apply Changes to the Team File

For Refinements

Edit existing team file direct. Keep consistency across all sections that ref team composition:

1. Frontmatter members[]: Add, remove, or update member entries (each with id, role, responsibilities)
2. Team Composition table: Must match frontmatter members exact
3. Coordination Pattern: Update prose and ASCII diagram if pattern shifts
4. Task Decomposition: Revise phases and per-member tasks to show new composition
5. CONFIG block: Update members and tasks lists to match (see Step 5)
6. Usage Scenarios: Revise if team activation triggers shifted
7. Limitations: Update to show new limits or remove resolved ones
8. See Also: Update agent links and add refs to new related teams or guides

Follow these edit rules:

• Keep all existing sections — add content, do not remove sections
• When add member, add them to ALL of: frontmatter, composition table, task decomposition, and CONFIG block
• When remove member, remove from ALL of those spots and reassign their tasks
• Check each member agent exists: grep "id: agent-name" agents/_registry.yml
• Keep lead in members list — lead is always a member

For Variants

# Copy the original as a starting point
cp teams/<team-name>.md teams/<team-name>-<specialty>.md

# Edit the variant:
# - Change `name` to `<team-name>-<specialty>`
# - Update `description` to reflect the specialized scope
# - Adjust `coordination` pattern if needed
# - Reset `version` to "1.0.0"
# - Modify members, tasks, and CONFIG block for the specialized use case
# - Reference the original in See Also as a general-purpose alternative

Got: Team file (refined or new variant) passes check list from Step 1, with all sections internally in sync.

If fail: Edit breaks internal sync (e.g., CONFIG block lists member not in frontmatter)? Compare frontmatter members[] vs Team Composition table, Task Decomposition, and CONFIG block to find mismatch.

Step 4.5: Sync Translated Variants

Required when translations exist. This step applies to both human authors and AI agents following this procedure. Do not skip — stale source_commit values cause npm run validate:translations to report false staleness warnings across all locales.

Check whether translations exist for evolved team and update to match new source state:

# Check for existing translations
ls i18n/*/teams/<team-name>.md 2>/dev/null

If translations exist

1. Get current source commit hash:

npm run validate:translations

2. Update source_commit in each translated file frontmatter:

npm run check:fence-propagation -- --id <team-name>
node tools/provenance-field.mjs --field fence_basis_commit --set $(git rev-parse --short HEAD) <mirror paths>

3. Flag files for re-translation by adding affected locales in commit msg:

evolve(<team-name>): <description of changes>

Translations flagged for re-sync: de, zh-CN, ja, es
Changed sections: <list sections that changed>

4. Regen translation status files:

npm run translation:status

If no translations exist

No action needed. Go to Step 5.

For variants

Wait translation of new variants until variant stabilizes (1-2 versions). Add translations after variant refined at least once.

Got: All translated files have source_commit updated to current commit. npm run translation:status exits 0.

If fail: sed fails to match frontmatter field? Open translated file by hand and check it has source_commit in its YAML frontmatter. Field missing? Re-scaffold with npm run translate:scaffold -- teams <team-name> <locale>.

Step 5: Update the CONFIG Block

CONFIG block between <!-- CONFIG:START --> and <!-- CONFIG:END --> must stay in sync with prose sections. After any member or task change:

1. Check every agent in CONFIG members matches member in frontmatter
2. Check every assignee in CONFIG tasks matches member agent id
3. Update blocked_by deps if task ordering shifted
4. Make sure synthesis/final task refs all prereq tasks

team:
  name: <team-name>
  lead: <lead-agent>
  coordination: <pattern>
  members:
    - agent: <agent-id>
      role: <role-title>
      subagent_type: <agent-id>
  tasks:
    - name: <task-name>
      assignee: <agent-id>
      description: <one-line>
    - name: synthesize-results
      assignee: <lead-agent>
      description: Collect and synthesize all member outputs
      blocked_by: [<prior-task-names>]

Got: CONFIG YAML is valid, all agents and tasks are in sync with rest of file, and blocked_by forms valid DAG.

If fail: Parse CONFIG block YAML apart to find syntax errors. Cross-check every assignee vs members list.

Step 6: Update Version and Metadata

Bump version field in frontmatter by semantic versioning:

Change Type	Version Bump	Example
Wording fix, See Also update	Patch: 1.0.0 → 1.0.1	Fixed stale agent link
New member added, tasks revised	Minor: 1.0.0 → 1.1.0	Added security-analyst member
Coordination pattern changed, team restructured	Major: 1.0.0 → 2.0.0	Changed from hub-and-spoke to parallel

Also update:

• updated date to current date
• tags if team domain coverage shifted
• description if team purpose materially different
• coordination if pattern shifted

Got: Frontmatter version and updated show size and date of changes. New variants start at "1.0.0".

If fail: Forget to bump version? Next evolve will have no way to tell current state from old. Always bump before commit.

Step 7: Update Registry and Cross-References

For Refinements

Update existing entry in teams/_registry.yml to match revised frontmatter:

# Find the team's registry entry
grep -A 10 "id: <team-name>" teams/_registry.yml

Update description, lead, members, and coordination fields to match team file. No count change needed.

For Variants

Add new team to teams/_registry.yml:

- id: <team-name>-<specialty>
  path: <team-name>-<specialty>.md
  lead: <lead-agent>
  members: [agent-1, agent-2, agent-3]
  coordination: <pattern>
  description: One-line description of the specialized variant

Then:

1. Bump total_teams at top of registry
2. Add See Also cross-ref in original team pointing to variant
3. Add See Also cross-ref in variant pointing to original

Run README automation:

npm run update-readmes

Got: Registry entry matches team file frontmatter. npm run update-readmes exits 0. For variants, total_teams equals real count of team entries.

If fail: Registry count wrong? Count entries with grep -c "^ - id:" teams/_registry.yml and fix count. README automation fails? Check package.json exists and js-yaml installed.

Step 8: Validate the Evolved Team

Run full check list:

• Team file exists at expected path
• YAML frontmatter parses with no errors
• version was bumped (refinement) or set to "1.0.0" (variant)
• updated date shows today
• All required sections present: Purpose, Team Composition, Coordination Pattern, Task Decomposition, Configuration, Usage Scenarios, Limitations, See Also
• Frontmatter members[] matches Team Composition table
• CONFIG block members match frontmatter members
• CONFIG block tasks have valid assignees and blocked_by refs
• All member agent IDs exist in agents/_registry.yml
• Lead agent shows in members list
• No two members share same primary role
• Registry entry exists and matches frontmatter
• For variants: total_teams count matches real count on disk
• Cross-refs two-way (original ↔ variant)
• git diff shows no slip deletes from original content

# Verify frontmatter
head -25 teams/<team-name>.md

# Verify all member agents exist
for agent in agent-a agent-b agent-c; do
  grep "id: $agent" agents/_registry.yml
done

# Count teams on disk vs registry
ls teams/*.md | grep -v template | wc -l
grep total_teams teams/_registry.yml

# Review all changes
git diff

Got: All check items pass. Evolved team ready to commit.

If fail: Fix each failing item one by one. Most common post-evolve issues are CONFIG block drift (members or tasks not matching prose) and forgot updated date.

Validation

• Team file exists and has valid YAML frontmatter
• version field shows changes made
• updated date is current
• All sections present and in sync
• Frontmatter members[], Team Composition table, and CONFIG block are in sync
• All member agent IDs exist in agents/_registry.yml
• Lead agent is in members list
• CONFIG block YAML is valid and parseable
• Registry entry matches team file
• For variants: new entry in teams/_registry.yml with right path
• For variants: total_teams count updated
• Cross-refs valid (no broken links in See Also)
• For refinements with translations: source_commit updated in all locale files
• git diff confirms no slip content removal

Pitfalls

• CONFIG block drift: CONFIG block, frontmatter, and prose sections must all agree on members and tasks. Updating one without others is most common team evolve error. After every change, cross-check all three.
• Forget to bump version: No version bump, no way to track what changed or when. Always update version and updated in frontmatter before commit.
• Stale translations after evolve: Every team evolve fires staleness in up to 4 locale files. Always check for existing translations with ls i18n/*/teams/<team-name>.md and update source_commit in each, or flag them for re-translation in commit msg.
• Orphan member refs: When remove member, their tasks in Task Decomposition and CONFIG block must be reassigned or removed. Leaving orphan assignees cause activation fails.
• Wrong coord pattern after evolve: Adding parallel-capable members to sequential team, or making hub-and-spoke team where agents need each other output. Re-check pattern pick from create-team Step 4 after any structural change.
• Team too big after add members: Teams with more than 5 members become hard to coord. Evolve push team past 5? Think split into two focused teams instead.
• Stale See Also after variant make: When make variant, both original and variant need ref each other. One-way refs leave graph broken.
