Each rung down relies more on\nan agent reading and obeying text.\n\n1. **Structure** - make the wrong action impossible or unnatural: a file layout, a name,\n a single entry point, a default that is already right.\n2. **Type** - a schema, a type, or a config field that rejects the wrong value.\n3. **Check or lint** - a script, a CI step, a hook, or a lint rule that fails loudly.\n4. **Test** - a test that turns red when the behavior regresses.\n5. **Prose** - a line in an instruction file.\n\nRules for climbing:\n\n- A mechanical rule (a forbidden character, a required flag, a file that must exist) is\n proposed as a check or a hook, with the prose line at most pointing at it.\n- A learning that comes back although a prose rule already covers it moves one rung up.\n Rewording the same line is not a fix: the line was there and did not hold.\n- Recording only names the higher-rung change in the note. A check, a hook, or a test is\n a code change: triage drafts it, it goes through the approval step like any edit, and\n the user may choose to keep only the prose line.\n- When the candidate stays on `prose`, its record names why the rungs above do not fit.\n\n## Rule forms\n\nPick the form by the kind of failure, not by habit:\n\n| Failure | Form | Shape |\n| --- | --- | --- |\n| An action did damage or wasted a run | prohibition | \"Do not X when Y: Z happens.\" |\n| The right command or sequence was found by trial | recipe | \"To X, run Y (not Z: reason).\" |\n| A required piece of an artifact was missing | template slot | a new field or heading in the template the project already uses |\n| Behavior differs by situation | condition | \"When X, do Y; otherwise Z.\" |\n\nA recipe copies the flags of the command that worked verbatim: shorten the explanation,\nnever the command. \"Connect with `psql -h \u003chost> -p \u003cport> -U postgres -d postgres`\" works\non a fresh cluster; trimmed to `psql -h \u003chost> -p \u003cport>` it fails on the missing role.\nStep 7 runs the written form before the note is recorded, and triage runs it again on the\ntext that goes into the target.\n\nWrite the rule, not the story. \"On 2026-10-21 the push failed because...\" is a story;\n\"Push with X when Y: otherwise Z\" is a rule. Dates, branch names, and who did what stay in\nthe session.\n\n## Placement surfaces\n\nBeyond the instruction files (root, nested, global, other repositories), a learning can\nbelong in:\n\n- **A file read during review** - a contributing guide, a review checklist, or a pull\n request template, when the rule is about what reviewers should catch.\n- **A glossary** - when the learning is a name: which term the project uses for a thing,\n and which old or ambiguous terms it replaces.\n- **A decision record** - only for a decision that is hard to reverse, not obvious from\n the code, and the result of a real trade-off. Record the options and why the chosen one\n won. Routine conventions do not get one.\n- **A \"why\" comment beside the code** - when the rule is about one place in the code and\n a reader there is the one who needs it.\n\nPrefer the surface the next agent will read at the moment it needs the rule. A rule in\nthe root instruction file is paid for on every session; a comment beside the code is\nread only where it applies.\n","content_type":"text/markdown; charset=utf-8","language":"markdown","size":3349,"content_sha256":"d35a79e25fb6153cbb744dd47d2958743105bf4c462217fc4d44005cc6f2d2a1"}],"content_json":{"type":"doc","content":[{"type":"heading","attrs":{"level":1},"content":[{"text":"Session Learnings","type":"text"}]},{"type":"paragraph","content":[{"text":"A session leaves knowledge the next agent would otherwise pay for again.

Session Learnings A session leaves knowledge the next agent would otherwise pay for again. This skill keeps what changes future behavior, writes it down at once where the next session sees it, and leaves the final placement to a later triage. It is the last link of the chain: it runs after , often once the work is already squashed into the base branch, or on its own at any point the user asks; under , starts it in the same turn after a successful action. It reads the session; it needs no artifact from an earlier skill. Recording asks no questions and edits only gitignored notes plus a one-tim…
