Self-Improving Agent

An always-on observer that captures user corrections and preferences, tracks repetition across projects, and escalates behavioral rules to the appropriate AGENTS.md file.

Two-Tier Activation

Tier 1: Observation (always in context)

The YAML description above is loaded every session. It contains everything needed for the lightweight per-message check:

1. After every user message, silently evaluate: did the user correct me, express a preference, or show frustration about repetition?
2. If yes, run one CLI command to record it.
3. Do NOT load the rest of this SKILL.md for observation alone.

Tier 2: Escalation & Writing (loaded on demand)

The sections below are loaded only when the agent needs to:

• Check escalation thresholds (/improve due)
• Write rules into AGENTS.md files
• Review the domain taxonomy or escalation logic
• Run /improve command

Observation Protocol

What to Capture

Record an observation when the user:

• Corrects the agent: "don't do X", "use Y instead", "that's wrong", "not like that"
• States a preference: "I prefer X", "always do Y", "from now on, Z"
• Expresses frustration about repetition: "again?", "I keep having to tell you", "every time", "I've said this before"
• Gives an explicit instruction: "remember this", "write that down", "note this"

What NOT to Capture

• One-time task instructions ("add a button here", "rename this variable")
• Clarification questions ("what did you mean by X?")
• Normal conversational flow
• Things already captured as identical rules

How to Record

uv run <skill-dir>/scripts/improve.py observe "<rule>" --project <name> [--domain <domain>] [--context "<what happened>"] [--explicit-scope global|local]

Rule phrasing: Write rules as imperatives. Bad: "user doesn't like pip". Good: "Use uv tool for Python CLI tools, never pip3 install".

Domain: Pick from the taxonomy below. If unsure, omit it (defaults to "unknown").

Explicit scope: Use --explicit-scope global when the user says "always", "everywhere", "in all projects". Use --explicit-scope local when the user says "in this project", "just here".

Project detection: If --project is omitted, the CLI auto-detects from git remote get-url origin.

Session Startup Protocol

At the start of each session, run:

uv run <skill-dir>/scripts/improve.py status

This loads all active rules into your context. Apply them during the session. Rules with written_to entries are confirmed — treat them as hard rules. Rules without are tentative — apply them but don't enforce rigidly.

Domain Taxonomy

Domains determine whether a rule should escalate to global or stay project-local.

General Domains (escalate to global when cross-project)

Project-Specific Domains (stay local even when cross-project)

If a rule's domain is unknown, treat it as project-specific until the domain is identified.

Escalation Decision Tree

After recording an observation, the CLI prints the recommended action. The full logic:

IF explicit_scope == "global":
    → Write to global AGENTS.md immediately (any count)

ELSIF explicit_scope == "local":
    → Never escalate beyond project AGENTS.md (any count)
    → Write to project AGENTS.md at count >= 2

ELSIF total_count == 1:
    → Apply in-session only, no file write

ELSIF total_count >= 2 AND cross_project == false:
    → Write to project AGENTS.md

ELSIF total_count >= 2 AND cross_project == true AND domain is general:
    → Write to global AGENTS.md

ELSIF total_count >= 2 AND cross_project == true AND domain is project-specific:
    → Write to each affected project's local AGENTS.md

ELSIF domain == "unknown":
    → Treat as project-specific, do not escalate until domain is identified

Checking for Due Escalations

At session end (or when the user runs /improve):

uv run <skill-dir>/scripts/improve.py due

This shows all rules that have reached their escalation threshold but haven't been written yet.

Escalating

uv run <skill-dir>/scripts/improve.py escalate --dry-run

This prints exactly what should be written to which file. To auto-write the rules to the correct AGENTS.md files:

uv run <skill-dir>/scripts/improve.py escalate --apply

This patches each AGENTS.md file (finding or creating the right ## Section based on domain), skips duplicates, records written_to, and marks escalation — all in one step.

Writing Protocol

When a rule is ready for escalation, write it into the appropriate AGENTS.md file.

Where to Write

How to Write

1. Read the existing AGENTS.md file
2. Find the appropriate section (or create one)
3. Add the rule as a concise bullet point — use the exact rule text from rules.yaml
4. Do NOT duplicate rules that already exist in the file
5. After writing, confirm:

uv run <skill-dir>/scripts/improve.py confirm <rule-id> --scope global|local

Formatting Rules in AGENTS.md

Write rules as concise, actionable instructions:

## Python Tool Management

- Use `uv tool` for installing Python CLI tools (never `pip3 install`).
- Use `uv run -- python -c "..."` for one-off Python commands (never `python3` or `python`).

Not like:

- The user has corrected me 3 times about pip. I should use uv instead.

Anti-Patterns

Over-Recording

Not every message is a correction. A user saying "try the other approach" is exploration, not a rule. Only record when the intent is clearly "do it this way from now on."

Premature Escalation

A rule said once is NOT a rule. Wait for repetition (count >= 2) unless the user explicitly says "always" or "everywhere."

Vague Rules

"I prefer clean code" is not actionable. Translate to specific behaviors: "Write functions under 20 lines. Extract helpers when logic exceeds 3 levels of nesting."

Conflicting Rules

If a new rule contradicts an existing one:

1. Record the new observation normally
2. Check which rule has more evidence (higher count, more recent)
3. If both are strong, ask the user which one to keep
4. Retire the loser by adding "retired": true to its entry in rules.yaml

Writing Without Confirming

Always run confirm after writing to AGENTS.md. Otherwise the system thinks the rule is still pending and will try to escalate it again.

CLI Reference

All commands use the improve.py script:

uv run <skill-dir>/scripts/improve.py <command>

Path Resolution

The CLI is located at <skill-dir>/scripts/improve.py. The skill directory is:

• Local install: .claude/skills/self-improving-agent/scripts/improve.py
• Global install: ~/.claude/skills/self-improving-agent/scripts/improve.py
• OpenCode: ~/.config/opencode/skill/self-improving-agent/scripts/improve.py

If unsure, search for improve.py within the skill directory.

Data Location

All data is stored at ~/.agent-improvement/rules.yaml. Override with AGENTIMPROVEMENTHOME environment variable.

Complete Workflow Example

Session Start

$ uv run improve.py status
  use-uv-not-pip
    rule: Use uv tool for Python CLI tools, never pip3 install
    count: 3 (cross-project, domain=python-tooling [general])
    escalation: global, written_to: 1 files

  check-pyproject-first
    rule: Check pyproject.toml before assuming library availability
    count: 1 (single-project, domain=tool-usage [general])
    escalation: none, written_to: 0 files

During Session (Observation)

User says: "Stop using grep for finding files, use glob instead."

$ uv run improve.py observe "Use glob for file pattern matching, not grep" \
    --project my-app --domain search-patterns \
    --context "user corrected grep usage for file search"
RECORDED (count=1) → apply in-session only

Same correction in another project, next week:

$ uv run improve.py observe "Use glob for file pattern matching, not grep" \
    --project other-project --domain search-patterns \
    --context "user repeated same correction about grep vs glob"
RECORDED (count=2, cross-project, general domain) → candidate for GLOBAL AGENTS.md

Session End (Escalation)

$ uv run improve.py due
  use-glob-for-file-pattern-matching-not-grep
    rule: Use glob for file pattern matching, not grep
    count: 2, projects: my-app, other-project
    → ESCALATE TO: global AGENTS.md

Agent reads global AGENTS.md, adds the rule, then confirms:

$ uv run improve.py confirm use-glob-for-file-pattern-matching-not-grep --scope global
Confirmed: use-glob-for-file-pattern-matching-not-grep written to ~/.config/opencode/AGENTS.md
