Improve used Skills from session evidence with ak-dogfood

Use ak-dogfood at the end of a session to turn what went wrong or slowly into better Skills. The Skill names every Skill the session used, shows where each one cost time, tokens, a retry, or a user correction, and proposes the smallest Skill change that would have prevented it, with the evidence, expected effect, and risk. By default it is a dry run and changes no Skill file.

Choose ak-dogfood for session lessons

Use ak-dogfood when

• A session just finished and you want to learn from its mistakes and slow paths.
• You own the Skills it used, as an AgentKit maintainer, contributor, or user.
• You want proposals tied to the responsible Skill text, not general advice.
• You want recurring problems across every local session, with --all.

Choose another workflow when

• You need to audit or optimize one named Skill across many past sessions. Use ak-skill-creator audit or optimize.
• You need to write a new Skill from scratch. Use ak-skill-creator create.
• You need a Git-history sprint review. That is a retrospective, not this Skill; ak-retro ships in Engineer Kit.

Prepare the session

• Complete Onboarding, and confirm Marketing Kit is installed for the runtime and scope you are using.
• Run the Skill in the session you want reviewed. It reads its own context first and the current transcript only when a compaction dropped facts.
• Keep ak-skill-creator installed: the inventory step runs its scripts/session_usage.py. When the script or transcript is missing, the Skill builds the same list from its own context.
• For the contributor lane, have an AgentKit checkout and an authenticated gh with push access. Without both, changes go to the personal-fork lane.

Pick a mode

--apply and --ask are exclusive; when both appear, the Skill uses --ask.

/ak-dogfood --ask --skill ak-plan

/ak-dogfood --ask --skill ak-plan

$ak-dogfood --ask --skill ak-plan

Understand what happens during a run

1. Inventory the session. The Skill runs session_usage.py --session latest from ak-skill-creator. It lists each Skill with its triggers and files and counts tool calls, errors, and duplicate calls by tool. A Skill with invoked: false was only named in paths, so it is not a used Skill. Each Skill gets its install path and owner. With --all, it runs session_usage.py --all instead and ranks every Skill used on the machine.
2. Review the whole session. It looks for failed and retried commands, repeated reads, sequential independent calls, unused or missing references, user corrections, skipped checks, re-derived procedures, and output rework.
3. Classify every finding. Each finding is a Skill defect, a preventable agent mistake, an environment or tooling fault, or a one-off. Only the first two become proposals; the others are reported in one line each.
4. Propose. One proposal per root cause, tied to the responsible file:line or the missing instruction, with a minimal hunk, effect, risk, and lane. Every content change bumps metadata.version.
5. Apply by lane when --ask or --apply allows it, then report with the Skills used, findings, proposals, items that are not Skill changes, what was applied, and unresolved questions.

Review every session with --all

With --all, the Skill ranks Skills by trouble, not popularity: interrupted sessions first, then the error and duplicate rate per session. It reviews at most five Skills and three lead sessions each unless you ask for more or narrow the scope, and it says how many it skipped. It reads only the stretches around counted errors, duplicates, and interruptions. A proposal needs the same cause in at least two sessions, or one user correction that the Skill text plainly caused; a pattern seen once is a watch item. Before proposing, it checks that the responsible text still exists in the current Skill.

Know where a change lands

The owner is resolved from the installed path and the install receipt, not from the name alone.

Contributor status is a live check: the checkout must verify against the canonical remote, and gh api repos/bestagentkits/agentkit --jq .permissions.push must return true. When either check fails or gh is unavailable, the Skill uses the personal-fork lane and says why. The bundled scripts/find_agentkit_repo.py locates the checkout on macOS, Linux, or Windows and is read-only.

Keep session data and approvals bounded

• A finding needs evidence from the reviewed session.
• A proposal must keep accepted behavior and quality; a token or time saving that drops a required check or artifact is a regression.
• A dry run writes no Skill file. The report may go to the project's reports directory when the project defines one; otherwise it stays in the reply.
• A store migration such as ak update --ssot runs only with your explicit approval. When ak is missing or too old for skills improve, the Skill stops at the proposals.

Verify the result

A complete run should give you:

• Every used Skill with its owner and lane.
• Findings with their class and evidence, described rather than quoted.
• Each proposal with its hunk, expected effect, and risk.
• In --ask or --apply, each accepted proposal applied in its lane with the lane checks passed, and the changed paths, candidate IDs, branch, and pull request link.
• Anything skipped, refused, blocked, or unverified named with its reason; none of it counts as applied.
