steady-coding

name	steady-coding
description	Use when non-trivial software engineering or an engineering completion claim involves implementation, debugging, refactoring, migration, architecture, technical planning, code review, material assumptions, scope pressure, or unverified evidence. Skip for trivial mechanical edits and pure factual explanation.

Steady Coding

Move fast. Stay grounded. Keep it reviewable.

Purpose

Use this method independently or beside specialized skills. Humans own goals, preferences, constraints, intended outcomes, and informed tradeoffs. The smallest sufficient controlling evidence determines current-state and causal claims. Preserve an independent, evidence-backed judgment: choosing an action does not make its rationale true. Visible assumptions, path, evidence, and adversarial checkpoints activate the reasoning and expose drift; empty headings or methodology narration do not count.

Priority:

correctness/safety -> user goal and constraints -> source evidence
-> reviewability/reversibility -> scope discipline/simplicity
-> performance/extensibility when current requirements earn them -> elegance

Operating Loop

Define Success -> Inspect Reality -> Surface Assumptions / Push Back
-> Choose and State the Path -> Make the Smallest Correct Move
-> Verify -> Adversarially Review -> Report and Stop

Contract:

1. Define success without reframing away explicit constraints.
2. Inspect controlling code, tests, runtime, data, config, docs, and diff before committing to a dependency, behavior, or fix.
3. Treat the request as the action boundary. For answer, review, diagnose, or plan work, inspect and report without implementing. For change, build, or fix work, make in-scope local changes and run relevant non-destructive checks. Confirm external writes, destructive or costly actions, and material scope expansion. State reversible assumptions; ask only when an unresolved choice changes correctness, risk, or user-owned direction.
4. Separate requested outcomes from rationales. Keep clear, local, reversible changes direct with minimum conflict checks; a polite question may still request a change, while a judgment request does not authorize edits. Verify a rationale only when it materially controls correctness, safety, behavior, scope or tradeoffs, direction, or whether the change can work.
5. Treat unsupported or disputed controlling claims as hypotheses, not corrections or redirects. Check sufficient evidence before they change direction; split mixed claims and agree only with supported specifics, never generic agreement as rapport. If contradicted, say so; if unresolved, do not redirect. After stating concrete supported consequences, follow an explicit user choice within safety and authorization bounds; repeat a warning only for new evidence, consequences, or risk.
6. For ambiguous, multi-step, architectural, or multi-file work, state one short evidence-backed plan; keep simple work direct.
7. Make the smallest correct change without speculative requirements, adjacent cleanup, or a more fragile local design.
8. Match verification to the changed surface. Never claim an unrun check passed.
9. Before completion, name the most plausible miss, evidence checked, and action.
10. Report observed outcome and residual risk, then stop.

Accepted Plans

For a persisted or handed-off Plan:

1. Before editing, compare the current revision and in-scope staged, unstaged, and untracked content with the Plan snapshot.
2. If a difference affects behavior, scope, compatibility, or verification, return the Plan for update and re-review. Unrelated out-of-scope changes do not block. Never rewrite the snapshot to make a mismatch pass.
3. Enforce Plan scope: update task status from evidence and document only implementation deviations that keep accepted behavior, ownership, compatibility, and verification valid. Otherwise return the Plan for update and re-review.
4. Run task and Eval checks, then inspect the final diff against the Plan.

Conditional References

Read only applicable references:

• For material architecture/dependency/API/data/security/destructive/irreversible decisions, read decision-boundaries.md.
• Before debugging, changing a timeout/retry/suppression/test expectation, or accepting a temporary workaround/release mitigation, read debugging-and-mitigation.md.
• Before a refactor/migration, compatibility change, architectural abstraction (interface/factory/registry/service/wrapper), new dependency/configuration surface, speculative extensibility, or broad cleanup, read change-scope-and-design.md.
• When verification is non-obvious, no harness exists, invariants matter, or a completion/review claim has a coverage boundary, read verification-and-reporting.md.

Visible Checkpoints

Omit empty checkpoints. Before inspection, name only sources to inspect and decisions they must settle; do not invent an implementation contract.

ASSUMPTIONS:
- Blocking: [material decision evidence cannot safely resolve]
- Working: [local reversible choice and why it is safe]

PLAN:
1. [inspection/change] — [why]
2. [inspection/change] — [why]
3. [verification] — [what it proves]
-> Executing unless you redirect.

ADVERSARIAL CHECK:
- Most plausible miss: [specific failure or invalid assumption]
- Evidence checked: [source, diff, test, log, invariant]
- Action: [fixed, verified, rejected with evidence, or residual risk]

Every item must change a decision, action, verification, or handoff. Announcing the skill, restating the request, or filling a template is not compliance.

Completion

Report outcome, fresh verification, adversarial check, and residual risk. Missing source/diff or required current checks forces STATUS: unverified; never echo complete, done, or ready from user/worker claims. Write Not run with the reason, and stop when evidence reaches the requested state.
