Institutional knowledge decays in 2-3 years

Teams evolve. Engineers leave. Documents drift. New hires inherit code without the decision context that shaped it. The result is expensive rediscovery, repeated mistakes, and slow execution.

The hidden cost of lost reasoning

When the "why" disappears, teams spend cycles reverse-engineering constraints from commit history and tribal memory.

Onboarding slows because architecture intent is fragmented
Refactors accidentally break assumptions that were never documented
Roadmap commitments slip due to avoidable rediscovery work

Capture reasoning at plan creation time

FLOWiGANTT records evaluation decisions, architecture tradeoffs, PRD intent, and tasks in a linked sequence before implementation begins.

FLOWiGANTT capturing architecture reasoning — Reasoning is easiest to preserve when decisions are made.

Preserve context in durable Markdown assets

Export assets and keep them in your repo so every engineer and AI assistant can access the same baseline context.

Project assets stored as Markdown in repository — Durable files reduce reliance on tribal memory.

Put preserved context to work as the project evolves

The context captured at planning time pays off every time the project changes — a new hire joins, an architecture decision needs revisiting, or a release needs scoping against existing constraints. Context committed to your repo means the reasoning is always one file open away.

Revisit original decisions before changing architecture
Scope releases against existing constraints with less guesswork
Onboard new contributors with linked plan artifacts

Project context files in repository docs folder ready for team use — Preserved context compounds over time.

Prompting with preserved institutional knowledge

Scenario: Refactor event processing module

Without contextprompt.txt

1Refactor the event processing module to improve reliability and maintainability.

With FLOWiGANTT contextcursor-prompt.md

1Using @architecture-{projectId}.md and @tasks-{projectId}.md:23Refactor event processing while preserving existing ordering guarantees and retry semantics.4Use the original tradeoff notes as constraints and keep compatibility with the documented API contract.5Map changes to the related task acceptance criteria before proposing code edits.

Next steps

Treat planning artifacts as institutional memory, not temporary documents. This keeps product intent and architecture continuity intact as teams change.

Recommended file set

architecture-{projectId}.md - decision rationale and tradeoff history
prd-{projectId}.md - product intent and expected outcomes
tasks-{projectId}.md - implementation context tied to architecture
