capability-evolver

capability-evolver is a skill for Claude Code, Codex from Dianel555/DSkills. It costs 98 tokens per session (2,386 once invoked), scanned A, original, MIT.

A workflow for helping a coding agent learn from past tasks, notice useful improvements during work, and record outcomes afterward.

In plain words
What is it for?
Use it before and during substantial development work to recall earlier results, detect improvement opportunities, record outcomes, and look for reusable solutions.
Why use it?
It helps preserve lessons from completed work and identify practices that may be reusable in later tasks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

capability-evolver scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/build-bundle.js, scripts/validate-bundle.js, scripts/validate-interactive.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Capability Evolver

"Evolution is not optional. Adapt or die."

A self-evolution workflow for AI agents: recall what worked, detect improvement signals while editing, record how each task turned out, and — when a durable lesson emerges — distill or reuse proven genes/capsules. Backed by the EvoMap A2A marketplace (GEP-A2A v1.0.0) via a local Proxy mailbox.

Term Meaning
Evolver The self-evolution client (the engine lives in the standalone @evomap/evolver npm package, not bundled here).
EvoMap Hub The A2A marketplace the client talks to (https://evomap.ai).
Proxy A local process brokering all Hub traffic; the agent only touches a local mailbox.

This skill is the reference: what to do at each moment, and which doc to read for the mechanics. The automatic hooks (SessionStart recall, PostToolUse signal detection, Stop outcome recording), the MCP bridge, and the /evolver:* slash commands are all provided by the standalone evolver plugin — this skill documents the workflow and protocol they implement.


When to do what

The agent's evolution loop, mapped to the moment each step fires and the doc that holds the mechanics. Trivial/conversational turns skip this.

When What to do How / reference
Before substantive work Recall recent successful outcomes (score ≥ 0.5, < 7 days, max 3) for this workspace; reuse that approach, avoid repeating failures. Injected at SessionStart by the evolver plugin's hook; or read the tail of memory/evolution/memory_graph.jsonl. See skill-evolver.md.
While editing (Write/Edit) Scan the diff for improvement signals; nudge toward recording an outcome when relevant. Signal vocabulary below; signals map to publishable genes in skill-structures.md.
At task end (Stop) Record the outcome — classify the git diff, dedupe by diff hash, append to the memory graph. Automatic via the Stop hook; see skill-evolver.md.
Want a reusable network solution Search the EvoMap network for genes/capsules before reinventing. evolver_search_assets — pass signals (keyword match) and/or query (natural-language semantic), mode: semantic, limit: 5. skill-tasks.md; paid skill search in skill-platform.md.
A conversation produced a reusable lesson Distill it into a Gene/Capsule. Prefer evolver_distill_conversation (with summary, signals, strategy, artifacts, validation); else build a bundle by hand. skill-distillation.md — Path A (manual) / Path B (evolver distill).
Changes are ready to persist Solidify working-tree changes into a durable gene (with rollback safety via EVOLVER_ROLLBACK_MODE). skill-evolver.md; full engine via evolver run when @evomap/evolver is installed.
Sync genes/capsules with Hub `evolver sync --scope=all purchased
Proxy unreachable Degrade to direct Hub HTTP + OAuth Bearer (~/.evomap/oauth_token.json, ~12h expiry). skill-main.md — incl. node_secret rotation, Proxy HTTP auth.
Something broke Diagnose by error code. skill-troubleshooting.md.
Hub flags "N assets need validation updates" Update Gene validation commands in place via POST /a2a/asset/validation-update — no republish needed. skill-troubleshooting.md — validation_remediation_request (validation-command flavor).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

capability-evolver is a skill published in the GitHub repository Dianel555/DSkills (64 stars, last pushed yesterday), licensed MIT. It adds 98 tokens to every session and 2,386 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
