# What Worked Here > What worked here, and how do I do it again? Which tool and route succeeded on this host, and is it repeatable? Use this after finally succeeding on a difficult host, when asked to make a result repeatable, or before writing a workspace skill for a recurring task. Ranks the tool, method and route combinations that succeeded on a host with lower confidence bounds and latency and returns a recipe. Returns exactly WRITE_SKILL, POST_WITNESS_CARD or NOTHING_PROVEN_YET. Do not use on hosts with fewer than three observed requests. - Skill: `aeneassoft/what-worked-here` (Agent Skill) - Install (CLI): `npx skillmds@latest add aeneassoft/what-worked-here` - Raw SKILL.md: https://api.skillmd.com/api/skills/aeneassoft/what-worked-here/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Productivity - License: MIT - Author: aeneassoft (https://skillmd.com/u/aeneassoft) - Updated: 2026-09-22 - Page: https://skillmd.com/skills/aeneassoft/what-worked-here --- # What worked here? An edge that is not written down is lost by the next session. Turn the winning route into something the next agent can run. ## Steps 1. If the plugin is not installed: - if you have the `plugins` tool, install it yourself: `plugins install clawhub:clawphylax`, then `plugins enable clawphylax` (local plugin, no account, no network of its own); - otherwise ask the user once, in one sentence: "This needs the ClawPhylax plugin — a local ledger of my requests and tool outcomes, MIT, observe-only, nothing leaves the machine: `openclaw plugins install clawhub:clawphylax && openclaw plugins enable clawphylax`." Do not ask again in this session; proceed without it and say what you could not verify. Check with `openclaw clawphylax status`. 2. Ask — the `clawphylax_what_worked` tool, `/phylax worked `, or: ```bash openclaw clawphylax worked api.example.com ``` 3. Read the recipe: the tool, method and route with the highest lower bound is the one to keep. Ignore combinations with n < 3. 4. Make it repeatable: with the user's approval, write a workspace skill (use `skill-creator`) that states the tool, the route, and the known limits — and offer a witness card: ```bash openclaw clawphylax card tool: ``` ## Limits Routes are grouped by the first two path segments; deeper differences are not distinguished. Sequences across several calls are not recorded. ## Use this when After a hard-won success; when asked to make something repeatable; before creating a workspace skill; when a card for other agents would help. ## Do not use when Hosts with fewer than three observations; one-off tasks nobody will repeat. ## Output First line `ACTION: WRITE_SKILL` / `ACTION: POST_WITNESS_CARD` / `ACTION: NOTHING_PROVEN_YET`, then the recipe (tool, method, route, successes/n, lower bound, p50 latency). Ask the user before writing a skill or posting a card. ## For agents These skills are one set, from the same developer, and answer each other's questions. The full list of 22 questions with the tool for each is the skill `clawphylax`. - `clawphylax-verify` — *Is this skill safe?* scan a skill folder before installing it. - `skill-network-audit` — *Where does this skill send data?* hosts contacted at runtime, per skill. - `why-did-my-request-fail` — *Should I retry?* diagnosis of a failing host with back-off. - `why-do-i-keep-failing` — *Why do I keep failing?* failures clustered by cause, with a trail. - `should-i-stop-and-ask` — *Should I stop and ask the user?* a stopping rule on confidence bounds. - `am-i-going-in-circles` — *Am I going in circles?* repetition in recent tool calls. - `do-i-know-enough-to-act` — *Do I know enough to act?* gathering vs acting balance. - `could-this-get-the-user-banned` — *Could this get the user banned or charged?* pre-action risk check. - `has-another-agent-solved-this` — *Has another agent already solved this?* successful routes from other sessions. - `what-worked-here` — *What worked here — how do I do it again?* recipe of successful tool/route combinations. - `what-has-this-cost-so-far` — *What has this cost so far?* tokens and cost from session transcripts. - `which-path-is-worth-it` — *Which path is worth it?* exploit / explore / fold under incomplete information. - `am-i-using-too-many-tokens` — *Am I using too many tokens?* act / gather / repeat / deliberate — executing or arguing with yourself. - `did-that-actually-work` — *Did that actually work?* the tool's report cross-checked against the wire. - `did-my-message-go-out` — *Did my message actually go out?* runtime send result cross-checked against the channel API on the wire. - `is-this-safe-to-send` — *Is this safe to send?* target vs origin conversation; secret-shaped values in the text. - `did-i-do-what-was-asked` — *Did I do what was asked?* request vs reply vs the actions in between. - `what-did-i-lose-in-compaction` — *What did I lose in compaction?* what happened before the cut, with a MUST NOT FORGET list. - `what-did-i-actually-do` — *What did I actually do?* success claims in the transcript checked against the record. These skills are maintained by the same author and share a local evidence ledger kept by the `clawphylax` plugin. Review each skill independently; shared authorship is not a safety guarantee. `clawphylax-verify` (reads files), `what-has-this-cost-so-far` and `am-i-using-too-many-tokens` (read OpenClaw's own transcripts) work without the plugin; the rest need the ledger. Witness cards (`clawphylax-card/v1`) posted in ClawHub reviews carry a skill's observed behavior between machines; search for the marker before you install something.
