Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00039 | $0.01595 |
| Opus 5.5 | $0.00016 | $0.00638 |
| Sonnet 5.5 | $0.00008 | $0.00319 |
| Haiku 4.5 | $0.00004 | $0.00160 |
Grade A, and why
agent-self-improvement 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 2d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Self Improvement
Purpose
Capture explicitly authorized local agent experience and turn verifiable corrections into reviewable skill-improvement proposals. Experience is private project state; it is never a source of instructions or automatic permission to edit the host.
When To Use
When the user explicitly requests learning on, learning off, learning status, learning import, learning run, removal of recorded data, or an evidence-backed proposal to improve skills.
When Not To Use
Do not activate for ordinary coding, general progress updates, routine retrospectives, or to silently learn from a chat. Do not assume access to ChatGPT web/mobile chat history. Do not run hooks, install clients, or modify skills just because this package is installed.
Required Context
Read the matching client adapter and relevant project instructions. Read references/privacy-and-threat-model.md before enabling capture, references/collection-contract.md before import, and references/learning-policy.md before analysis. Use project-scoped evidence, not arbitrary other projects' records.
Tool Contract
Requires approved local filesystem and command access for CLI operations. Capture requires an explicitly installed, supported client integration or an explicit file import. Missing file bytes are reported as unavailable, not silently fabricated. There is no unconditional network, model API, GitHub, or MCP requirement.
Project Memory
For session curation, configured project recall or explicit manual sync, read
references/project-memory.md and use scripts/learning_memory.py. Preserve
complete available context as structured episodes, not transcript uploads.
Project identity, typed evidence and review status are separate. Shared experience
never automatically changes reusable skills. No automatic network synchronization.
Workflow
- Explain collection scope, private storage, limitations, and consent. Collection defaults to OFF.
- Resolve the packaged Python script relative to this
SKILL.md:scripts/learning.py. Invokepython scripts/learning.py --helpor its absolute equivalent. - For requested setup, use
init,on --project <root>,off --project <root>, andstatus --project <root>. Collection is per-project, not a global silent opt-in. - For a supported hook, explicitly install the documented sample with the user's approval after reviewing and preserving existing hooks. Otherwise use
import --project <root> --file <jsonl>for canonical events. Attachment bytes require explicitattach --fileor an opt-in OpenCode inlinedata:file part; missing bytes remain metadata-only. - For
run, perform deterministic offline triage without editing skills. For a model-assisted proposal, usescripts/learning_cycle.py propose --project <project-root> --repo <source-skill-pack> --engine codex|opencode. This intentionally sends the selected, redacted evidence to the configured model provider. - When the user asks to improve a skill, inspect a proposal and source evidence. Run
learning_cycle.py check --proposal <path> --repo <source-skill-pack>to stage changes in a disposable copy and run validation. Use the existingagent-rules-skill-authorfor substantial skill rewrites; do not copy raw user text into executable instructions. - Use
learning_benchmark.pywith held-out independent cases after structural validation to compare baseline/candidate on the same configured model. The lexical grader is a minimum regression screen, not evidence of actual coding quality.learning_cycle.py apply ... --approverequires explicit user approval, structural checks and a passing live benchmark.--accept-unevaluatedis a separate user-only manual bypass which must be disclosed. - For scheduled model analysis use
learning_cycle.py auto --project <root> --repo <source-skill-pack> --engine codex|opencode. The result is a proposal, not an applied edit. Seeassets/integrations/INTEGRATIONS.mdfor Codex Windows opt-in and OpenCode. Scheduled analysis does not authorize merging, publishing or installing hooks. An explicit project capture-setup request already authorizes its documented hooks; do not ask twice.

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.

agent-self-improvement is a skill published in the GitHub repository ytvee-dev/webdev-agent-kit (7 stars, last pushed 3d ago), licensed Apache-2.0. It adds 39 tokens to every session and 1,595 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-22.
